I know I'm going to get raked over thr coals for this one, but: UA 744/777/763 IPTE F suite > CO 752 BF. I mean, definitely.

i know, i know, how dare I...but I mean, wouldn't the UA F suite be "the best seat in the domestic skies" technically speaking? I just did the regularly scheduled domestic 3 cabin 763 (i.e. sfo-ord) and had an epiphany:

Seat 1K F-Cabin / IPTE 763 - the best damndest seat on the whole United Airlines, on any plane. Anybody who's flown it knows exactly what I'm talking about.
