I work a lot with Polish crew, quite a few from LOT themselves and they all tell the same stories about how you don't want to be a foreigner there and even toxic cultures among Polish crew regarding hierarchy and rank. And if you can make more money in Poland working for Ryanair Poland or Wizz... I think you are doing something wrong as national carrier. I am at the moment making more money on a regional jet left seat than I would in the right seat or even a lot of cases in the left seat of a LOT 787. And I am living in a country that is not really much more expensive in terms of living costs...
