Have an upcoming transatlantic flight on a 757. SWU looks tight so suspect I will be sitting in coach. Are there any differences in configurations between the domestic and international 757s? Yes, I've checked seatguru. I'm safely ensconced in 18C but could have 9B unblocked if folks think it would be better. Actually kind of curious - despite all my trips overseas, have never done a transatlantic trip on 757.
