Flying JFK-EZE in Feb 09 and trying to decide coach seats (this flight was a gift, otherwise I would have def used miles for BE!). Anyway, I've never been on a DL 763 and I don't know what normal coach seats are like. I'm 6'7 so I assume 21 would be the best option in terms of leg rooms, but is it gross sitting right next to the lav on an 11 hour flight? Should I try for a bulkhead instead? My flight is showing a row 19, so no extra legroom in 18. Any advice would be greatly appreciated.
