Complete Guide To Airlines That Allow Bid Upgrades In 2025
July 1, 2025
Understanding Airline Upgrade Bidding Systems
Before diving into specific airlines, it's important to understand how these bidding systems typically work. Airlines use sophisticated algorithms that consider factors like route popularity, seasonal flight demand, and current premium cabin occupancy to determine winning bids. As a premier member or elite status holder, you might even receive priority consideration in some cases.
How Airline Upgrade Bidding Works
- Book a regular fare class ticket
- Receive an email invitation to bid (typically 7-10 days before departure)
- Submit your cash bid for an upgrade within the airline's specified range
- Wait for confirmation (usually 24-48 hours before departure)
- If successful, pay the bid amount and enjoy premium seats
Major Airlines Offering Upgrade Bidding
North American Airlines
Air Canada leads the pack with its AC Bid program, allowing passengers to bid on premium economy and business class seats up to 48 hours before departure. Unlike traditional mileage upgrade awards, these bids require only cash payments.
United Airlines occasionally offers PlusPoints bidding opportunities to premier 1K members, though this differs from their standard systemwide upgrade certificates program.
European Carriers
Lufthansa provides a comprehensive bidding platform for premium or business class upgrades on long-haul routes. The Star Alliance member typically sends upgrade offers 7 days before departure.
Aer Lingus focuses its bidding system on transatlantic flights, with complimentary upgrades sometimes offered to frequent flyers who regularly participate in the program.
Middle Eastern And Asian Airlines
Emirates, while no longer offering Skybid Auction, has shifted to a combination of miles/co-pay options and airport upgrade opportunities.
Singapore Airlines stands out by allowing passengers to use a mix of cash and KrisFlyer miles for bids, providing more flexibility than traditional mileage upgrade awards.
