We’re on a round trip DFW-HNL in June and we’re fortunate enough to find ourselves on a 789 out and a 773 on the return. We’re traveling in business class with a family member who may need help in the restroom due to a disability. We’d like to be seated near the larger handicap bathroom. Any advice on the closest seats to the larger restrooms on these planes? We think we remember from a flight to SYD years ago for the 789, but have no clue on the 773/77W.
