Its nice to have a plan but it’s not a very realistic plan.
A lot of large European National carriers hire predominantly from their own flight academies and if not from a selected few schools.
Which means you need to have done your training at a specific school. For instance Lufthansa Flight Academy or the KLM Flight academy for their respective airlines.
You’ll need to be fluent in the language and they will requires citizenship or EU Citizenship.
Which means that’s a 5-7 year delay before you can even apply at the school.
So that’s pretty much impossible.
I would suggest you look at Poland, Greece and Jordan for your flight training.
Then look for jobs in Africa, Middle East and Asia.
There will always be jobs for people willing to sacrifice and move to wherever that job might be.
I have known a handful of people that have flown tourists in Africa before moving on to airline jobs, also know people that have flown in Indonesia and PapuaNG.
