In 2026, the answer for major airlines is still strictly no. Due to global security regulations and anti-fraud policies, a flight ticket is a legal contract tied to the specific name on the passport or ID used during booking. You cannot simply "hand over" your boarding pass to a friend. Most "Legacy" carriers (Delta, United, Emirates) have a non-transferable policy; if you cannot fly, you must cancel for a credit (if eligible) and book a new ticket for your friend at the current market price. However, some Low-Cost Carriers (LCCs) allow a "Name Change" for a substantial fee, often ranging from $75 to $150, plus the difference in fare. This is effectively a transfer, but it must be done through the airline's official system at least 2 to 4 hours before departure. If you have "Cancel for Any Reason" (CFAR) insurance, you can get a refund and then purchase a new ticket for your friend, which is often the most cost-effective way to handle the situation in the modern travel landscape.
