Now on many international air carrier flights there is a more civilized way to compete with fellow passengers: a seat upgrade auction. How it works is fairly simple: a week or so before a flight, passengers receive an email letting them know about potentially available seat upgrades. But no other major U.S. carriers offer upgrade auction programs. "Most major U.S. airlines offer a few ways to upgrade your flight experience, whether you're looking for extra-legroom, premium economy or business-class seats. From the airline's perspective, there will be a highest bidder, and those who don't win the auction are no worse off than before.
