Back in the 'good old days' of BOAC seniority was absolute.
Getting on the bus was Captain first then FO then Flight Engineer then Senior cabin crew member then everyone else.
This was repeated at the hotel and again for collecting allowances.
Captain was entitled to a bigger, better room and then rooms went down the list.
The most junior crew member had to watch the bags and usually had to give up their room for room party.
These days I have seen the Captain guarding the bags and the junior crew texting from the comfort of the air conditioned bus!
Thats progress I guess
