Plenty of things had change when Poland became member of EU. Borders opened a lot, plenty of Polish citizens start to working in different countries. Also, because of that, cheap airline carriers showed up in our country, with a lot of new flights to exotic places.
Flying by a plane is not a piece of cake. You must to know a lot of thinks before you get inside of it, and even much more earlier. What to put inside carry on baggage, and what difference is with checked luggage? Can I bring any kind of food on board? And what about cosmetics? And flying with pets? What documents do I require when I am a disabled person? Might I have a snowboard equipment with me? And plenty more. And what with some specific destination? What you need to know when you are wishing to travel to/from Canada or USA?
