Getting a job as Cabin Crew is all about YOU not qualifications and degrees.
If you like people are good at handling them and have a lot of patcience then this is going to stand you in much better stead than a degree in history.
Get into an industry involving customer service first and see if it's for you - e.g. bar work - you'll find most cabin crew at some stage have done it (and sampled the products as well!!!). Also on a CV a string of jobs involving customer contact shows what type of person you are. See if you can handle the pressure of a saturday evening witha bar of people 3 deep all pissed and swearing at you because you didn't serve them first. If you can keep you head and still be polite after a few months of that then cabin crew may well be the job for you!!!
Good Luck!!
