Crossing International Boundaries & License Regognition
I was reading into hour building overseas for PPL licence holders and understand that they have to apply to the country in question in which they wish to train in, in order to have their license verified, converted etc. It got me wondering; where commercial pilots, especially long haul ones fly in and out of many countries and potentially fly over many others, what happens with them? I assume they don't have to apply to have their licenses recognized by dozens of different countries? Do airlines simply agree with each country that they can fly in/out/over them and said county trusts that their pilots are adequately licensed, or does it work differently?
