However, the problem with measuring minimum seat size by "pitch" is not right. The thickness of the seat is a huge factor that pitch does not account for. The ultra slimline seats on frontier actually give plenty of legroom with less pitch. I've sat on both united and AA economy recently and it's unquestionably less legroom than frontier. Comfy seats, but terrible legroom.
The FAA simply can't go with pitch, it's a bad metric to use
I agree, I regularly commute on Delta and when getting a regular coach seat on an MD88 my knees always hit the bar of the seatback magazine storage thing and it becomes uncomfortable very quickly. On Spirit my knees don't touch the seat in front of me even though the pitch is several inches less. Granted the Delta seats are probably more comfortable to sit on for someone who isn't 6 feet or taller. But the whole "lack of legroom" doesn't hold any weight in my opinion...
