This is because many airlines will have a cut-off point for name changes (generally up to 24 hours before the flight). Mistakes of up to three letters are normally undertaken without charge, however, major name changes will normally incur an additional cost.

Changing a name on a plane ticket the day before departure is extremely difficult and often impossible in 2026 due to strict security regulations. Airlines generally do not allow "Name Transfers" (giving your ticket to someone else) to prevent the reselling of cheap tickets. If you have a minor typo (e.g., "Jon" instead of "John"), most airlines like Delta or United will correct it for free or a small fee if you call immediately. However, for a full name change (e.g., due to marriage or legal change), you must provide legal documentation. If you try to change it 24 hours before, you may be forced to cancel the ticket and rebook at the current last-minute price, which is often triple the original cost. Some 2026 "Flex" fares allow for easier changes, but for "Basic Economy" or standard tickets, a name change this close to takeoff is treated as a cancellation, potentially leaving you grounded unless you are willing to pay a massive fare difference.
