Premium econ. seats (the true version of AF and several Asian carriers, not the UA Y+) are for me a superb value choice on long flights. I would gladly book a W and not worry about the upgrade. BE is nice, but if I am on my own dime all I need is some room.

Yoo DL-

I have had about 2 dozen TPAC trips that I booked on non-DL metal for this reason, and I live in ATL. HINT!
