BAs F seats were designed by Contour, UAs new F seats are made by B/E Aerospace so they are different seats however there are only so many way to package what in essence is the same general design for a seat. As for who's better I would say that BA
has a better soft product but UAs suite does beat out BAs hard product in a number of areas.
I know the voices in my head aren't real but sometimes their ideas are just awesome!!!
