@Okavango: For some people it will be a great bonus to skip doing their job that they do really not like, of course if they have already enough money for the course (life expenses will be a lot less in Poland than UK). Also afterwards when working for the airlines if you choose to live in eastern Europe only then you will "feel the reward" not only in job satisfaction but also financially, because of the price level where you live.
@pilot freak: Most schools in Poland today offer different opportunities for students who are good enough. At my school its the possibility to be a fully paid FI and fly actually as much as you only wish and can manage properly. All the instructors who instructed me in my PPL(A) in 2018 and applied to the airlines got there. One to Sprint Air (turboprop), one to Wizz Air and one to LOT (on a jet). And BTW the one who got Wizz Air waited the longest patiently (no one had to wait more than 1 year).
PS. 2 of the instructors were in their 30s and one exactly 40 years old when they got their airline jobs so age in the market today is not such an enormous problem like it seems in some topics. I am 30 and will probably be 31 when I am done so I hope too its "young enough" for the airline job
