The caps do remind one of a 1950's American Good Humor icecream vendor and there is another style of that same cap I can't attach a profession to but it is also 50's.
It only will really work if they also get female flight attendants back in short dresses and stockings and have them stow everything for passengers in the overhead holds. That might be 60's but the flashbacks work nicely for me!!
Super Connie on gate 1 would also work.
Best all
EWL - awaits incoming flak
