For 99% of major airlines in 2026, you cannot change the name on a ticket to a different person. Due to post-9/11 security regulations and anti-fraud policies, a ticket is considered a non-transferable contract between the airline and the specific individual named. If you can no longer travel, you must typically cancel the ticket for a refund or "eCredit" and have the new person book a separate flight. There are two 2026 exceptions: Low-Cost Carriers (LCCs) like Ryanair or Frontier occasionally allow a full name swap for a high fee (often $150+), and legal name changes (due to marriage or court order) are always processed for free if you provide documentation. Additionally, some "Flex-Pass" corporate tickets in 2026 allow for passenger swaps. For standard economy passengers, however, the name on the ticket must match the government-issued ID exactly, and "giving your seat to a friend" remains a logistical impossibility on legacy carriers.
