Can I Upgrade My Seat After Booking?

Quick answer

Usually, yes — most airlines let you upgrade after booking, through paid upgrades, bid systems, or miles redemptions, subject to your fare class and open seats. Some options close before departure; complimentary grants, where they exist, are decided by the airline near travel day.

Your post-booking options

• Buy the upgrade outright when the airline offers it on your fare
• Bid through the airline's system, if it uses one
• Redeem miles, where award space exists in the higher cabin
• Wait for day-of-travel offers, which some airlines release at check-in
