21 Travel Hacks Only Frequent Flyers Know (and You Should Too)

19. Leverage Last-Minute Bid Upgrades

Airlines often auction off unused premium seats close to departure, allowing passengers to bid on upgrades. These last-minute opportunities can provide a luxurious travel experience—think business or first class—at a fraction of the usual cost. To participate, check your airline’s website or app for upgrade options after booking your economy ticket. Some carriers send email invitations a few days before your flight, enabling you to submit a bid within a specified range. The trick is to research typical upgrade costs and bid strategically—low enough to save money but high enough to outcompete others. Tools like SeatGuru or airline forums can provide insights into how much to bid. For frequent flyers, this hack offers a chance to travel in style without breaking the bank, turning long-haul flights into a more comfortable and enjoyable experience while keeping costs reasonable.
