5 Common Reasons You're Not Receiving Miles for Your Flights and How to Fix Them - Forgetting to add your frequent flyer number during booking





One frequent cause for not earning miles on flights is simply forgetting to enter your frequent flyer number when you initially book the flight. It's a common error, but easily avoidable. While most airlines permit you to add your number after booking through their "Manage My Booking" section, it's an extra step that can easily be forgotten. Keep in mind that most airlines have a timeframe for requesting missing miles, often within six months, so prompt action is necessary if you realize you've missed it. Proactively saving your frequent flyer information within travel booking websites or platforms can also prevent future issues. It's also a good practice to confirm you have correctly inputted your number before completing the booking process to avoid any complications.

A frequent oversight leading to missed mileage accrual is the simple act of forgetting to input your frequent flyer number during the initial booking. Thankfully, most airlines understand this slip-up and provide a post-booking avenue for rectifying the omission. Many airline websites include a "Manage Booking" section, often accessed with your reservation confirmation or PNR, allowing for the addition of your frequent flyer information after ticket purchase.

However, there’s a time constraint involved. Airlines generally have a cut-off for retroactive mileage claims, often around six months following your flight. This timeframe varies depending on the carrier, so it’s crucial to act swiftly if you discover the oversight after completing your travels.

It's important to note that, generally, award tickets – those purchased with points or miles themselves – don't generate further mileage accumulation. There can be limited exceptions, though, often related to elite status or promotional campaigns. Consulting the particular airline’s program terms will clarify any possible exceptions.

Should you find yourself without a readily accessible ticket number for submission, some programs, like American Airlines' AAdvantage, provide specific customer service routes for missing mileage requests. This can often help if you're facing difficulty accessing past bookings online.

While many airlines provide user-friendly interfaces for post-booking mileage adjustments, the processes can differ. If the general 'Manage Booking' options don't present the opportunity, search for a dedicated section related to Frequent Flyer or member details.

When booking, particularly via third-party sites or travel agencies, examine if they allow for the storage of your frequent flyer details for automatic inclusion in future bookings. This can be a convenient way to prevent this type of error from occurring again.

And, as always, meticulously double-check that you've entered the correct frequent flyer number when initially making the reservation to avoid discrepancies or potential issues during crediting. If, despite diligence, you discover missing miles post-flight, it’s usually best practice to initiate a mileage credit request through your frequent flyer program's online platform. The vast majority of loyalty programs provide a clear pathway for addressing these situations. The more informed you are about the procedures and timelines involved, the better your odds of getting those miles back into your account and maximizing your reward earning potential.

5 Common Reasons You're Not Receiving Miles for Your Flights and How to Fix Them - Flying on a fare class that doesn't earn miles





5 Common Reasons You’re Not Receiving Miles for Your Flights and How to Fix Them

One of the most frustrating reasons for not accumulating miles on your flights is booking a fare class that simply doesn't earn them. Many budget-focused fare classes, such as L or T, are known for not contributing to your mileage balance or offering a heavily reduced rate. This can be a shock for travelers who rely on miles for future travel plans or upgrades, as they might not realize their flight won't earn miles until it's too late.

It's also important to understand the impact of fare classes on your mileage accrual, especially if you're focused on travel rewards. Airlines sometimes make mistakes in their systems and accidentally assign the wrong fare class to a flight, which can mess with your ability to accumulate miles. Always take a careful look at the details of your fare before booking to avoid any surprises with respect to mileage accumulation. Further, ensure the frequent flyer number linked to your account is associated with your flight. Neglecting this step often results in missed opportunities to credit your travel to your loyalty program.




One of the more perplexing aspects of frequent flyer programs is the way airlines handle mileage accrual based on the fare class of a ticket. Many budget-focused fares, like W or O, are designed to be competitively priced, but they often come with restrictions that impact your ability to accumulate miles. Some airlines have adopted the practice of offering specific fare classes that earn no miles at all, which can be especially frustrating for those aiming to accumulate rewards for their travel.

Furthermore, airlines have different approaches to managing this. Some low-cost carriers are upfront about this, plainly stating which fare classes aren't eligible for mileage accumulation. Others may allow partial mileage credit, emphasizing the importance of thoroughly reviewing airline policies related to specific fare classes.

The structure of many frequent flyer programs themselves is shifting away from the traditional approach of rewarding pure flight distance, and some now focus more on spending. This shift can be particularly impactful for travelers who primarily rely on budget fares, potentially limiting their ability to gain miles.

It's also important to consider airline alliances. While beneficial for travelers who frequent multiple carriers, flights within the same alliance may not always offer consistent mileage accumulation across all fare classes. Certain fare categories might be treated differently under the specific rules of individual airlines within an alliance.

Many credit cards offer bonus points or miles on airfare, yet this incentive often does not apply to fare classes that don't earn miles within frequent flyer programs. This disconnect can easily lead to missing out on valuable opportunities if you aren't paying attention to the intricacies of your rewards system.

Furthermore, various promotions by airlines offering bonus miles can also be affected by your chosen fare class. Booking a ticket in a fare class that is ineligible for a promotion can mean missing out on potential rewards.

Another point to consider is how fare class limitations can negatively impact your ability to qualify for elite status. Achieving these tiers offers a host of advantages like upgrades, extra baggage, and priority services – highly attractive for frequent flyers. However, without earning enough miles through your flights due to fare class restrictions, the journey towards elite status becomes a significant challenge.

Additionally, the impact of fare classes on mileage accumulation can extend beyond individual airlines to airline partnerships. If you're a member of one airline's program but flying on a partner airline in a restricted fare class, your mileage accumulation may be zero. This emphasizes the need for a clear understanding of how airline alliances manage these different restrictions.

Occasionally, you may encounter special promotional periods when airlines make even their lowest fare classes eligible for mile accumulation. But, these periods are typically short, and it's necessary to stay informed to capitalize on such earning opportunities.

Interestingly, in some cases, booking a flight directly through an airline's website might provide better opportunities to accrue miles than using third-party booking sites. Third-party websites might not accurately input your frequent flyer details or highlight the limitations of specific fare classes impacting your rewards. This adds another layer to the complexity of optimizing mile accrual.

The evolving nature of frequent flyer programs and how fare classes influence mile accrual can be perplexing. Careful scrutiny of specific fare rules and program terms is a constant necessity for maximizing rewards, especially in this era of evolving loyalty programs.



5 Common Reasons You're Not Receiving Miles for Your Flights and How to Fix Them - Booking through third-party websites instead of directly with airlines





Using third-party websites to book flights instead of going directly through the airline can create unexpected hurdles for travelers aiming to collect frequent flyer miles. These sites often act as a go-between, essentially placing your booking with them rather than the airline itself. This can create confusion when it comes to earning miles, especially if the fare class used doesn't comply with the airline's rules for earning points. In addition, booking directly with airlines often unlocks perks you might miss out on when using third-party websites. Airlines frequently have exclusive deals, special customer service benefits for direct bookings, and sometimes even better upgrade options. While the lure of lower prices from these platforms can be tempting, it's crucial to consider that you may be sacrificing opportunities to earn valuable rewards and potentially save money on future trips. It's often worthwhile to check if booking directly offers a better deal, comparing both prices and the rewards structure.

Reserving flights through third-party websites instead of directly with airlines can sometimes create unexpected complications when it comes to accumulating miles and earning travel rewards. It's a practice that seems convenient, but it can have subtle consequences for frequent travelers.


One of the main drawbacks is the uncertainty of earning miles. Third-party booking sites might not seamlessly transfer your frequent flyer number to the airline, causing a disconnect and potentially leading to missed miles or points. This is particularly important for those who strive to achieve elite status or redeem rewards.

There's also the issue of transparency around fare classes. Third-party platforms don't always provide detailed information regarding fare class restrictions, which can be crucial for understanding whether a particular ticket qualifies for mile accrual. Many budget fare classes, designed to be inexpensive, often don't count toward earning miles, catching travelers off-guard.

Booking directly through airlines often opens the door to promotional offers that aren't available through third-party sites. Airlines can tailor promotions specifically for direct customers, creating a loss of opportunity if you haven't booked directly with them.

It's worth remembering that airlines often prioritize customers who book directly when it comes to loyalty program benefits. Some programs and airline perks might only be available if you have booked directly with the airline. This is especially true for elite status benefits or bonus points, which some programs will limit to direct bookings only.

Problems can also emerge during the linking process between the booking platform and your loyalty program. The connection between third-party platforms and airline programs might not be fully integrated, causing a delay or even failure to properly credit miles to your account. This often necessitates a manual claim process, adding an extra layer of complexity to the process of claiming miles and points earned.

Each airline can also establish specific rules regarding mileage accrual depending on the source of the booking. Booking directly can often translate to a higher accrual rate compared to tickets purchased via third-party channels. Understanding these specific policies per airline is crucial to avoid discrepancies and potential loss of rewards.

When unforeseen circumstances arise requiring a flight change or cancellation, resolving those issues through a third-party platform can become cumbersome and challenging. Airlines often show preference to passengers who booked directly, sometimes delaying assistance and complicating any claim for lost miles.

Beyond issues with miles, there are concerns around data security and the handling of your personal information. Third-party websites don't always have the same level of security protocols as airline websites, which can expose your information to increased risk.

Also, when it comes to credit card-linked airline benefits, those often only apply when the ticket is purchased directly from the airline. Third-party platforms may not be recognized for earning credit card points or miles, resulting in fewer rewards for frequent flyers using specific credit card promotions.

Airlines often maintain more detailed and consistent records of frequent flyer interactions with those who book directly. This helps them provide personalized services and recognize high-value customers who consistently support their loyalty programs. Booking through third parties might lead to missing out on these customized benefits and experiences.

Understanding the nuances of how airlines and third-party platforms work together can be perplexing, particularly when it comes to accruing miles and gaining the maximum benefit from your travel. It's important to weigh the conveniences of third-party booking sites against potential limitations when it comes to earning miles and maximizing travel rewards. Carefully reviewing airline policies and program terms is crucial for maximizing rewards in this evolving landscape of frequent flyer programs and third-party platforms.



5 Common Reasons You're Not Receiving Miles for Your Flights and How to Fix Them - Not completing the full itinerary as booked





5 Common Reasons You’re Not Receiving Miles for Your Flights and How to Fix Them

Not finishing your entire planned flight route as initially booked can have consequences for earning miles. If you miss a flight within a multi-leg itinerary, the airline might invalidate your entire ticket, meaning all your remaining flights could be canceled. This is particularly true if your whole booking is on one airline. Missing just one segment often leads to losing your whole booking. It's crucial to understand your responsibility when booking flights. Failing to show up for a flight without letting the airline know will nearly always lead to your other flights being canceled. This also applies to tactics like "skiplagging" or "hidden city ticketing," where people book a flight with a layover but don't take the last leg. Deliberately skipping flights to get cheaper fares can cause issues, including a total loss of your ticket and your opportunity to earn miles.

## Not Completing the Full Itinerary as Booked

One frequent reason for not receiving the expected miles for a flight is failing to complete the entire itinerary as initially booked. This can stem from various situations, some deliberate and others unintentional. While it’s a common practice to file for missing miles, the act of not flying a segment can lead to complications.

It's important to remember that fare classes have a significant influence on how miles are awarded, especially if parts of the itinerary are canceled. Some budget-focused fares, aiming to provide attractive prices, might include restrictions that hinder mileage accrual if you don’t complete the entire booked trip. These penalties can range from reduced mileage to the complete forfeiture of any rewards for that specific booking.


Not completing a planned travel route can have consequences for achieving elite status within a frequent flyer program. Failing to reach certain mileage thresholds can derail progress towards coveted benefits like priority boarding, extra baggage, or upgrades. Missing flights translates to fewer earned miles, potentially causing travelers to fall short of their elite status goals.


Travel involving multiple airlines and code-share agreements presents further complexities. When parts of a booking are missed on partner airlines, the rules regarding mileage credit can become a source of confusion. Each airline within a partnership may have its own criteria for how travel on a partner's route contributes to a program. This highlights the need for thorough research about each airline's policies before traveling.


Low-cost airlines generally impose strict rules regarding itinerary completion. These carriers typically have limited flexibility and can severely penalize travelers who skip a segment. If you miss a leg of your trip, they might instantly disqualify your entire booking from receiving any miles, potentially leading to significant dissatisfaction for passengers expecting some flexibility.


Airlines usually have strict cancellation procedures if you fail to show up for a flight without informing them. Subsequent flights linked to the itinerary are very likely to be canceled, leading to complete loss of miles for the whole booking. Travel plans can be completely disrupted, impacting further journeys.


Insurance can provide a level of protection for unforeseen events but might have limitations regarding missed flights in an itinerary. Travelers reliant on travel insurance should meticulously review the terms to understand their coverage. It's essential to check if skipping a connection within an itinerary is covered, as this can be a missed element in insurance policies, resulting in loss of miles or refunds.


Changes within airline code-sharing agreements can create unexpected challenges when segments aren't completed. This can quickly become a source of confusion, particularly when multiple carriers operate under different policies. The complexity arises when each airline within the agreement has its own set of rules for awarding miles. It's crucial to ensure that all flights are flown if you are attempting to maximize rewards from a code-share booking.


Airlines typically establish timeframes for claiming missing miles, usually a span of around six months. This policy can further complicate matters when a trip is incomplete, potentially resulting in a missed opportunity to claim any miles at all. If the missed segment occurs at the beginning of a multi-city trip, it may be too late to file a claim within the timeframe, making it crucial to review these airline-specific guidelines prior to traveling.


Dual credit claims in loyalty programs can also become difficult if itineraries are only partially completed. When tickets cover flights across multiple airlines, it can be challenging to determine the allocation of miles for each carrier. This is further complicated if segments aren't flown, causing issues with segment-based earning in certain loyalty programs and fragmented mile accruals.

Understanding how a disrupted itinerary affects your mileage accumulation is key. Thoroughly reviewing terms and conditions, fare rules, and partner airline policies will contribute to a smoother and more rewarding travel experience.



5 Common Reasons You're Not Receiving Miles for Your Flights and How to Fix Them - Failing to keep your frequent flyer account active





Letting your frequent flyer account sit idle can lead to the loss of the miles you've diligently earned. Many airlines have policies that close accounts after a period of inactivity, usually 18 to 24 months without any activity like earning or redeeming miles. This can mean losing all those accumulated rewards. The best way to keep your account active is to engage with it, even if it's just a small action. Flying, redeeming miles for travel, and using partner programs – like those with hotels and rental car companies – are obvious ways to maintain the account. But, even less frequent interactions, such as using an airline's co-branded credit card or participating in dining programs linked to the airline, can help prevent closure. Keeping a close eye on your account's status is especially important if you're relying on those miles for future trips and don't want to lose them.

Airline loyalty programs, while seemingly designed to reward frequent travel, often come with hidden stipulations – specifically, the requirement for maintaining a level of account activity. Many programs, after a period of inactivity, typically 18 to 36 months, will either expire your accumulated miles or, in some cases, even deactivate your account entirely. This can be particularly frustrating for travelers who may have accumulated miles over a longer period but haven't had the opportunity to use them.

American Airlines, for instance, explicitly warns members that inactivity can lead to account closure, though point expiration is more frequent than outright account removal. This is something that casual or infrequent travelers may not always be aware of.


It's not difficult to maintain account activity. You can earn or redeem miles in various ways, like booking flights, hotels, or car rentals through airline partners. Every transaction you make resets the expiration clock on your miles, providing a reprieve from the looming inactivity risk. Several airlines even partner with restaurant reward programs, allowing you to rack up miles simply by dining at specific eateries.

Renting a car and providing your frequent flyer number can also keep your account active, even without being tied to an airline ticket. Similarly, using an airline-branded credit card for everyday purchases helps to prevent the penalties of inactivity. It's worth noting that programs like Lufthansa Miles & More have unique conditions. For them, miles can persist for 36 months, but only if you meet specific conditions like maintaining elite status or holding a specific credit card.


Some programs rely heavily on retaining members and preventing miles from expiring. American Airlines' AAdvantage program, for example, emphasizes using miles in conjunction with other mileage-generating activities to keep the account active. This creates an environment where you need to continually engage with the system to retain any benefits.


The overall impact of these policies can be significant. Not being aware of these hidden rules can quickly lead to disappointment. Further, frequent flyer programs and the associated airlines are constantly evolving. Terms of service and expiration policies change frequently, emphasizing the need for regular review to avoid unexpected loss of rewards.


The shift of some airline reward programs away from a focus on purely flight distance to a broader focus on overall spending with the airline and partners adds another layer of complexity to the issue. Understanding how these policies are evolving is crucial to remain on top of your rewards program, especially for infrequent flyers.




Many of these frequent flyer schemes are evolving towards a more dynamic model. This includes dynamic reward charts for travel redemption which may make redeeming miles harder if you are not consistently engaged with the program. Simply retaining your miles is no guarantee of being able to redeem them for desired travel.



Understanding these nuances can be difficult, and it's important for travelers to take proactive steps to avoid losing their accumulated rewards. Maintaining activity, even on a small scale, can go a long way towards ensuring the longevity of your travel benefits.
