You can typically change seats through the airline's website, mobile app, or by calling customer service. Some seats become available closer to departure as the airline releases blocked inventory.

When is the best time to select seats?

The best time varies by strategy. Book immediately after purchasing your ticket for the widest selection, or wait until 24 hours before departure when airlines often release blocked premium seats. For popular routes, early selection is recommended. Our seat alerts can notify you when preferred seats become available.

Are the seat maps updated in real-time?

Our flight seat maps are updated regularly throughout the day to reflect current availability. However, seat availability can change rapidly, especially close to departure. We recommend checking the airline's official website for the most up-to-date information when making your final selection.

What if my preferred seat isn't available?

You can also check back periodically as seats often open up closer to departure when other passengers make changes or when the airline releases additional inventory.
