Clever Ways to Score a Free Seat Upgrade on Your Next Flight
2. Work the 24-Hour Upgrade Window

Airlines often reshuffle seat assignments within 24 hours of departure, making this a crucial window for securing an upgrade. As soon as check-in opens, logging in and requesting an upgrade can increase your chances. Many airlines process elite status upgrades first, so checking the seat map after this process can reveal available first-class seats. Once at the airport, inquiring politely at the gate about unclaimed premium seats may result in an upgrade, especially if the flight is not full. Pro Tip: If you see an empty seat in business class, politely ask the gate agent about upgrades after check-in opens.
