Unfortunately when a 767 is being used as a first/coach configuaration, the ratio of first class seats to coach is very small compared to something like a 757. This hurts upgrade chances.
I'm having a try at getting into "monster seat" class for an upcoming ORD-SFO flight, but I'm currently booked for row 9 of "coach"
When are the 767's getting fully flat seats? Not that you need a bed to travel from ORD to SFO, but I've never tried them and this would be a nice taste.
