Traveling by a plane isn't a piece of cake. You have to know many 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? May I take any sort of meals on board? And what about medicament? And flying with pets? What documents do I require when I am a disabled passenger? Can I have a diving equipment with me? And many more. And what with any specific destination? What you have to know when you are wishing to travel to/from Canada or United States?
