Hi there!
I used to work for Ryanair based out of STN and had a fab time with all the crew, you do work long hours and paying for your uniform and training is a bit of a dag but like you say it is a first step into Cabin Crew. Once you have started flying the money will come rolling in!
The Crew are so friendly and you will make some really good friends. Good luck with what you decide and I wish you all the best!
