When I fly, I always prefer to sit in an aisle seat. There are a few reasons why the aisle is my choice.
First of all, I don’t want to bother anybody if I need to get up to go to the restroom or get something out of my bag in the overhead bin. I also like that I can stretch my leg into the aisle, even for a few seconds if the space feels a bit tight. The last reason I like the aisle is so that I can quickly get my bag out of the overhead bin upon landing.
