Generally, no, you cannot sell a standard plane ticket to another person in 2026 due to strict international security and anti-fraud regulations. Tickets are legally tied to the name on the government-issued ID of the original passenger. However, there is a "conditional yes" for certain Low-Cost Carriers (LCCs) like Ryanair or EasyJet, which allow full name changes for a significant fee (often $75 to $150). If your airline allows a name change, you could theoretically "sell" the ticket to someone else, though you must usually pay the fare difference between the original price and the current market rate. For major legacy carriers like Delta or United, the ticket is strictly non-transferable; the best you can do is cancel it for a flight credit in your own name. Platforms like SpareFare exist to help match people who want to sell these changeable tickets with buyers, but the transaction is always subject to the airline's specific, often expensive, name-change policies.
