I learned very early on in my life with DL to NEVER accept row 25 on a 757. The first time was the last time. It is absolutely the worst row on the aircraft.
Don, I absolutely agree about the last 2 rows on the MD-80. I happened to be sitting in a "window" seat in the last row a couple of years ago when the nearside engine gave out with a loud bang about 10 feet from my ear. Talk about making a bad experience worse!
