Does anyone know if Lufthansa or any other airlines have opted for the upper deck galley stowage option? This was supposed to free up 12 seats resulting in 479 passengers in a Boeing configuration. Granted, no one is using that particular seating configuration, but the extra floor space should be worth at least 8 seats in a Lufthansa config.

Seems like a rather simple way to improve CASM.

I don't believe they have, based on looking at the galley positions on their seat maps.

I have a "related" question... Wouldn't it be more efficient if Boeing installed the stairs to the upper deck the other way around (walking up the stairs from the back to the front of the aircraft)? This way the slope of the rear of the upper deck would not be wasted and would free up more space for seats.

From a space efficiency standpoint you're probably correct, however that puts the bottom of the stairs away from any exits. As it is now the bottom of the stairs are aligned with Exit 2 I making for more efficient boarding.

Not to mention that they need to be by doors in a ditching situation as the UD doors are not sliderafts.
