Yes, in 2026, you can fly standby on an earlier flight, but the ease and cost depend on your airline status and fare class. Most major U.S. carriers (like Delta, United, and American) offer "Same-Day Standby" for free to all passengers, though you will only get a seat if one remains open after all confirmed passengers and upgraded elites have boarded. If you want a "Same-Day Confirmed" change—guaranteeing you a seat on the earlier flight—airlines usually charge a fee (around $75), which is often waived for high-tier loyalty members. To fly standby, you should check in via the airline's app as early as possible (usually 24 hours prior) and look for the "Change Flight" or "Standby" options. A "pro-tip" for 2026 is to check your position on the standby list in real-time on the app; if you are #20 on the list for a flight with only 2 open seats, you’re better off heading to the airport bar than the gate. Standby is a "space-available" gamble, so always have a backup plan in case the earlier flight is completely full.
