Each domestic US airline has recently announced that it will no longer charge change fees. It's amazing. It can be difficult to remember all the details. What fare classes are available? If the new flight is less expensive, can we keep the difference in the fare? Are there any standby fees? What happens to award change fees? Each airline will have a different answer. These are just a few of the quick reference tables that can be used to help answer these questions.UPDATE 8/6/2021 - Delta made some positive changes. Added a COVID related waiver. Customers who booked Basic Economy can make changes on their flights to travel between 7/28/21 and 12/31/21.Basic (non-elite members) can now be on standby for same day earlier flights free of charge, but only if a confirmed change is not possible. Confirmed same day changes still incur fees. For those who fly within the United States, Puerto Rico, or the U.S Virgin Islands, same-day standby is available.
