I hope this is the correct place for seating questions:

I'm flying a Delta 757 from DTW to ATL and I'm looking at EC seats. I'm wondering what the story is with Row 19, seats D and E. There doesn't appear to be a window seat in this row. Is that correct? Would my wife be able to put her carry-on between her seat and the window after takeoff, or is the emergency exit there? We're looking for plenty of legroom (I'm 6'4") and wondering if Row 20 A and B would be better.

Next flight is a Delta 747-400 from ATL to HNL. Does Row 22 have decent leg room? Looks like there's a bathroom in front (which concerns me a bit).

Last flight is a Delta 737-900ER from SEA to DTW. I'm looking at Row 10 seats A and B. Extra leg room?

I apologize if these are dumb questions...
