The best airport if you like spotting is HNL, fatty. They have outdoor walkways that are wing level to the jumbos. We departed our Continental 764 and walked by 4 JAL 747-400s sitting so close you could jump on the wing. Kona also deplanes by stairs, which is cool because United stops their OGG-ORD 777 there for cleaning on the way back to the main-land. Not many places you deplane a wide body on stairs.
