Any recommendations on the best coach seat on the A340 (as flown by Air Canada)? Would it be bulkhead aisle (12C) or towards the back by the rear exit but behind the washrooms (31C)? I think 12C might be the best but don't know if there is kick space (or whatever you call the cutaway at the base of the bulkhead) which would be a must for a 12 hour flight.
