Airline Change Fees Explained: Which Airlines Charge Them (and Which Don't)
"Change fee" policies vary widely by airline and, just as importantly, by the specific fare you purchased. Two passengers on the same flight can have very different change rights depending on whether they bought a basic economy fare or a standard/flexible fare.
Why change fees differ by airline
Several major U.S. carriers moved away from charging standalone change fees on most published fares in recent years, meaning a date or time change is often limited to any fare difference rather than a separate penalty. Other airlines, especially ultra-low-cost carriers, generally still charge a change fee on their base fares unless you purchase an add-on bundle designed to include free changes.
Why fare class matters more than the airline name
Within a single airline, a "Basic" or "Light" fare is typically the most restrictive tier, while "Flex," "Plus," or premium-cabin fares generally allow more flexibility. Before assuming an airline "charges" or "doesn't charge" change fees, it's worth checking which fare family your ticket falls under.
- Basic/Light/Bare fares: usually the most restricted, limited or no free changes outside the 24-hour window
- Standard/Main fares: often changeable for a fare difference only
- Flex/Plus/premium fares: generally the most flexible, sometimes fully changeable or refundable
