Even if you’ve cross-checked your sources, called your airline and waited until the precise optimal date to book your flight, a sense of panic can set in after the final ticket purchase is made. You’re locked. You’re loaded. You’re taking this flight, and there’s no turning back. Right?
Not quite, if you’re a fan of the same-day flight change. This little-known process allows you to change your domestic flight on almost any major airline for minimal or no fee, provided you swap for a flight that leaves on the same day as your original. It’s pretty much the best thing an indecisive traveler could imagine.

*Most airlines require you to swap for a flight that leaves on the same calendar day as your original one. A notable exception is United, which allows you to swap for any flight that departs within 24 hours of the time your request is made.
