Mrs. Ex and I were unfortunate to have been offered EWR-AMS on CO on a single aisle 757 when booking on UA.com. Currently we are in 7 B/C. I was on a UA 757 last week and the amount of folk waiting for the toilet in front of these seats was mind boggling, more like a convention or party. I assume after a 9 hr flight it starts smelling as well. Now as far as the exits are concerned, the good seats are gone. Two seats in row 20 would be available, but of course limited recline. How bad is the limited recline compared to the toilet stuff in row 7? Does anyone have any experience?
