Yes, most airlines offer the option for passengers to select their seats in advance, but this often comes with additional fees. The seat selection fees can vary depending on factors such as the airline, the type of seat (standard, preferred, extra legroom), the route, and the timing of the selection (during booking, at check-in, or at the airport).
If you've purchased a ticket and want to choose your seat, you can typically do so during the booking process. Airlines usually provide a seat map where you can see available seats and choose the one that best suits your preferences, such as aisle, window, or specific location within the cabin.
If you didn't select a seat during booking or want to change your seat later, you can usually do so by managing your booking online through the airline's website or mobile app. Keep in mind that if you choose to select or change your seat at the airport or during check-in, there may be limited availability, and you might not get your preferred seat.
