Picking a seat on United Airlines, also known as United Airlines Seat Selection, is simple. When booking your flight, you can choose where you want to sit. If you're not sure or want to decide later, you can do that on their website or mobile app. If you have specific preferences, like wanting more space or sitting with your group, it's best to choose your seat early. United Airlines gives clear instructions to help you easily pick the seat that suits you. For more details on United Airlines Seat Selection, read a blog on the Airlines Pet Policy website.
