Bid for First or Business Class Seats Cheaply

Airlines offer bidding systems where passengers submit offers for unsold premium seats, often securing first or business class upgrades at a fraction of retail prices. Travelers check airline apps or emails post-booking for bid invitations, typically with minimums starting low and deadlines 24-72 hours before departure. Successful bids depend on demand, but tips include researching recent sales and bidding strategically above the minimum yet below full fare.
