Is it impolite to decline a request to swap seats on an airplane?

It is not impolite to decline a request to swap seats on an airplane, but it is important to handle the situation politely and respectfully. You are not obligated to give up your seat, and there may be valid reasons why you need to keep it. For example, you may need the extra legroom of an exit row seat or have a medical condition that requires you to sit in a specific location.

When declining a seat swap request, it is best to be honest and explain your reasons for needing to keep your seat. You can say something like, 'I'm sorry, but I need the extra legroom for my bad knee' or 'I have a medical condition that requires me to sit in this location.' It is important to be firm but polite in your response, and to avoid being confrontational or rude.

If you are willing to swap seats, but not with the person who has asked you, you can suggest other available seats that may be more suitable. However, you are not obligated to do so.

Ultimately, it is up to you to decide whether or not to swap seats. It is important to prioritize your own needs and comfort, but also to handle the situation with respect and consideration for others.
