Yes, you can absolutely ask for a window seat at the check-in counter, but your success will depend on your timing and the airline's specific policies. In 2026, many "preferred" seats (including windows) are often reserved or pre-paid by other passengers weeks in advance. However, airlines often "hold" certain seats for families, groups, or "operational reasons" that are only released when the check-in window opens. The best strategy is to arrive at the airport as early as possible or, even better, use the airline's mobile app exactly 24 hours before departure to see the "live" seat map. If you are already at the counter, a polite request to the gate agent—such as, "If there are any window seats left near the front, I would love to be moved"—can occasionally yield results, especially if there have been last-minute cancellations or upgrades. If you have a "Basic Economy" ticket, the agent may be less likely to help for free, as those fares usually include a fee for seat selection. However, if you have a medical reason or are traveling with a young child, agents are often more flexible. It never hurts to ask, as the "seat assignments" are often in flux right up until the boarding process begins.
