As of July 2024, international airlines are increasingly standardizing their carry-on size limits, with most adopting a 21.5 x 13.5 x 9 inches (55 x 35 x 23 cm) policy.

This shift towards uniformity aims to simplify the travel experience, but it's worth noting that some budget carriers maintain stricter regulations.

Savvy travelers should still double-check specific airline policies, as exceptions and variations persist, particularly on routes involving smaller aircraft or remote destinations.

The International Air Transport Association (IATA) attempted to standardize carry-on size limits in 2015 with a proposed "optimal size" of 5 x 5 x 5 inches, but this initiative was abandoned due to backlash from airlines and passengers.

Some airlines, like Ryanair, have peculiar carry-on policies that allow only a small personal item for free, while charging for larger carry-on bags, effectively turning their "low-cost" model into a potential financial pitfall for unprepared travelers.

The strictest carry-on size limit among major international airlines belongs to Air Asia, permitting bags no larger than 22 x 14 x 5 inches, which is significantly thinner than the typical allowance.

Lufthansa's carry-on weight limit of 6 pounds (8 kg) for economy class passengers is one of the lowest among major international carriers, potentially catching frequent flyers off guard.

Several Asian airlines, including All Nippon Airways and Japan Airlines, have specific size restrictions for musical instruments as carry-on items, allowing violins and violas but not larger instruments like cellos.

Despite the prevalence of hard-sided luggage, some airlines like Emirates still recommend soft-sided bags for carry-ons, as they are more pliable and easier to fit into overhead bins or under seats.
