Generally, the greater your frequent flyer status, the more likely you are to get upgraded to First Class. But even if you don't have top-tier status, there are ways to increase your chances, such as arriving early for check-in, dressing professionally, and politely asking the gate agent if any upgrades are available.

Upgrading to first class after you have already checked in is still possible, but your options become more time-sensitive and limited to the remaining available inventory. The most common method in 2026 is using the airline's mobile app; even after checking in, many apps will display a "last-minute upgrade" banner or a "view seats" option where a cash or miles buy-up offer may appear at a significantly reduced rate. If the app doesn't show an offer, you should visit the airport check-in counter or the gate agent specifically. Agents have the most up-to-date view of the "load" and may offer "gate upgrades" to fill empty premium seats for a fixed fee, which is often cheaper than the original fare difference. For elite status members, this is also the window where "complimentary upgrades" are processed based on the standby list. Another strategic move is to keep an eye on your email, as some carriers send "last chance" upgrade bids or offers up to an hour before departure. Always ensure you ask politely at the gate, as "revenue" upgrades (paying cash) are generally prioritized over non-revenue requests.
