Iberia Subasta Upgrade is a service offered by Iberia Airlines that allows customers to bid on upgrades from their original booking class to a higher class of service. This unique program provides an opportunity for travellers to experience the luxury and comfort of first or business class at significantly discounted prices while also allowing the airline to maximise its seat capacity. The bidding process begins when Iberia invites eligible customers via email to participate in the auction, which usually occurs between one week and 48 hours before departure.
