Also there are no baggage bins next to window seats (that exist upper deck on B747-400's or LH B747-800's). But upper deck is upper deck - once B747's and A380's are gone there will be no upper deck any longer... Even knowing the limitations, I somehow cannot resist from reserving an upper deck seat.
Then there will be 737s and A320s doing long hauls. Same cabin width at the 747 upper deck (and arguably the same experience, minus the flexible cabin foor)
