Well, I was on the 757-200 from LAX
and I found the 757 to be very comfortable. But, I hear that is not as nice as it was when I flew on the 757 last. I felt the seats on the old 757 the green and pink boxes on them were going to be uncomfortable because they did not have the head reasts like I was use to but they were VERY comfortable for my 4 and a half hour flight. I had the best inflight experiance with leg room on the return flight when I boarded the 737-800 with the new blue seats that are on the 767's, MD80's and the 777's. I had soo much leg room and much comfort ( this was a 5 hr and 15 min flight). Well, I hope this helps and have a great flight with American Airlines. They are a great airline to me and I can not wait till I fly them again. I would like to fly their A300-605r's before they dissappear.
