I'm sorry to say , but - do you REALLY want a career in such an unstable profession? I have been very lucky to have retired with a bucket full of flying hours and qualifications behind me, but it is not the same these days.
Yes, aviation has always been cyclical, but never such as today.
I would personally advise any potential pilot to think very carefully on the upfront costs and likely benefits from the airline industry.
There are other things to do in life!
