Remember the lounge upstairs on the 747-100?
If I remember correctly the 'upstairs' area was designed as the crew rest area. Before service entry airlines thought a cocktail lounge for the posh would be more appropriate and the flight crew unions acquiesced: I don't remember the details. When the hump extended some bright spark thought to add more business class seats. A/C range increased and FTL's increased in line with performance. Funny thing that, but some unions had enough clout to bring in crew bunks etc., even for cabin crew. The non-union airlines suffered.
Would that the original concept had survived. The downward path of the past 4 decades is littered with such tales, starting with Nav's, FE's etc.
