Well I can relate very much to this topic. Right now I am 17 years old turning 18 years old in April. It is my last year in High School and I do have plans to become a airline pilot. Now I am living in the United States and in order to get your major airline job you need a 4 year degree ( This is mandatory unlike UK or some other European nations). Well a few months ago I had to think to myself what I would do to get to the cockpit. I decided to go to Flight School (FLIGHT SAFETY IN FLORIDA) first get my CIME and CFII with a future plan to enroll into a UNI right after the Flight School and instruct at the same time to build my hours. This will most likely get me a job faster and at a younger age. The only problem with this is that you will need a lot of money. Flight Safety is a very expensive school but the training is outstanding and of course its in Florida where the weather is good
. You are still 15 years old and you have a lot of time to think. Getting a College degree is necessary in the US but not in Europe. But think about it, the more you have the more you can compete.
