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.
