Another friend recently made his maiden flight on Premium Class and what better way to do it on a Transpacific flight.
He was in San Diego for a conference and he managed to try the famed Delta One Business Class Suite (on the Narita to Seattle Segment) which was operated on their new A350-900.
On the way back, he was on a Korean Air Boeing 777-300ER with a very outdated 2-3-2 shell seat (oh, they still have such seats in Business Class nowadays?!)
