Seat Expert is a website that allows you to see a complete seat map of the specific aircraft that you'll be flying on. By inputting your airline, flight number and departure date you're able to view the exact airplane that you'll be taking and see where your seat ranks. It shows green seats for desirable spots all the way down to red seats which are spots you want to avoid if possible. It also compares legroom depending on your row, how large your lay down bed is, and which seats recline the furthest.

Since Seat Expert does not sell tickets, research the specific seats you want and call Payless Flights to secure that spot. Happy seat hunting!
