I usually prefer bulkheads but not sure of proximity of rest rooms on this 767-200
The beat seat is the one where you sit and wait for the flight to end. Which is pretty much all seats on your plane, regardless of class or seat position. I see you prefer a close proximity to the bathroom, so in order to give you the beat advice I must know; do you or will you be packing a urinal tract infection, gastro, will you have eaten a copious amount of chillies the night before your flight, or are you simply a mile high addict? about 8 years agoAnswered by Mind Bullets via Travellr.com
Seatguru shows the rest rooms are only at the front, but the front bulkhead style seats apparently have "some drawbacks". I'm pretty sure that'd be due to high traffic/being too close the the rest rooms, but really, how much traffic are you going to get with each restroom serving about 12 people? I'd personally just go one of the front few rows.
Either side is going to have some spectacular scenery on the flight down. I'd bring up google maps and choose which countries/side of the plane would interest you more.
