... the following promise by Ryanair ...
With respect, just do a search using "Ryanair" and work out the answer for yourself. You can then set the temptation against the "Ryanair uncertainty principle" and make a decision. (In other words, the same answer as applies to - among several examples - the following question: "I am a 200 hour CPL/IR and the only people prepared to offer me a job are Ryanair, but I have to pay up-front for a type rating, but they have offered me a full-time post with great money .... should I accept?).
Answer: do your research (not least on this site) and make your mind up. You are only inviting a repetition of a well rehearshed debate that has taken place many times.
