People travel by train, by plane, by ship or boat and by car. All means of travel have their advantages and disadvantages. And people choose one according to their plans and preferences.   The best way of traveling is by plane, as it is the fastest and one of the most comfortable means of travelling. Passengers are requested to arrive at the airport 2 hours before departure time on international flights and an hour on domestic flights, as there must be enough time to complete the necessary airport formalities. Before passengers get on board the plane, they have to register their luggage. Each passenger is given a boarding pass to be shown at the departure gate and again to the stewardess when boarding the plane. Landing formalities and custom regulations are more or less the same in all countries: while still on board the plane the passengers are given arrival cards to fill in. After the passengers have disembarked, officials will check his passport and visa. Then the passengers go to the custom for an examination of their luggage. As a rule personal belongings may be brought in duty-free. In some cases the custom inspector may ask you to open your bag for inspection. #JonSnowAlive
