Call me crazy - (waits for the thread) - but if I can get bulkhead on an Airbii/767/777, I am quite happy with UA's Economy product. Plenty of legroom, the 18" seats are comfortably wide enough for my bum, and the FAs still care on my flights.
I fly a good deal less in upgraded First now thanks to the extra 5K miles need each way (only on transcons, and then only on three-class or 757s), but I'm doing just fine for the most part.
