If the upgrade is not successfully applied, it's important to contact a Delta agent before travel to ensure the certificate is properly utilized.

The changes to Delta's upgrade policies, including the inability to apply RUCs online and the requirement to have the ticket reissued, have been a point of frustration for some travelers.

However, Delta is reportedly working on introducing a feature in 2023 that will allow customers to add upgrade certificates themselves, potentially streamlining the process.
