Have you ever wondered how you can get a good seat on plane? Take a look at Seat Guru.
You simply take your seat assignment if you have one—choose the Airline–choose the type of plane you are flying on–and you will see a diagram of that airline’s seat configuration. You can then request the seat you want. I always check out the plane configuration prior to booking so I can get the seat I want. The site also warns of seats that are too close to the bathroom, in an exit row, and that does not recline all the way.
