OH - and completely OT - I have a warning for everyone who books a flight on a US Airways flight that is using a 757 jet. NEVER BOOK YOURSELF IN ROW 7 on the D-E-F side of the plane. Those were the worst seats ever - the backs didn't recline because they were right up against the bathroom, and they actually sat forward a bit...and then when the people in front of you put their seats back - they were in your lap. It was terrible, and they were the worst seats ever. It also smelled, due to the bathroom being right there. < / end rant >
Well, I don't know. I don't travel ~all~ that much lately.
You can ask if your seats are against the bulkhead on any plane or configuration. While the last row before the bulkhead are awful seats... the first row behind the bulkhead are great seats.
