1forall: The best way to find out the requirements is to look for such vacancies on airlines' websites and see what they ask for. What you mean by benefits is not quite clear, but if you like very frequent travel and hotel accomodatiion you might consider cabin attendant work as beneficial.

Someone I know calls the role that of a 'waiter/waitress in the air' but it's actually a bit more than that because in addition to delivering customer service, they undergo safety trainings too. However the sky is the limit in that field, and career progression is not really great. Once you've moved to the senior cabin attendant/purser position, there really are no further options.
