How many airlines will keep those options? The 747 had an upstairs piano bar when it first came out. Is it still there? (I've never been upstairs on the 747) Or was it replaced with seats for paying passengers.
I think Airbust is scrambling to catch up.
Last time I flew a 747, the upstairs was a "lounge" with nothing but seats. But the seats were not for sale, nor did they want passengers to fly the entire trip up there. I talked the stew into letting me do so on an overnight Pacific crossing to escape my closest fellow passengers who were obnoxious drunk loudmouth rock musicians. As I recall, the lounge was only accessible from first class. Very spacious.
