When preparing to fly, passengers are requested to arrive at the airport 2 hours before departure time. They must register their tickets, get a seat assignment, and weigh and check their luggage.
Most airlines have at least 2 classes of travel, first class and economy class. Economy class tickets are much less expensive. Each passenger more than 2 years old gets a free luggage allowance. Generally this weight limit is 20 kg of checked baggage for economy class passengers and 30 kg for first class passengers. If you check excess luggage youll have to pay a fee calculated by the number of extra pieces and the extra weight. Every passenger is also allowed one small carry-on bag, for instance a laptop computer or small suitcase.
The rules for passengers who are traveling abroad are similar in most countries but there are, sometimes, slight differences. Here are some things to remember: if, for instance, you need to go through Customs, try to fill in the customs declaration before you talk to the customs officer. He will ask every passenger the same, routine questions about whether he is carrying anything he wants to declare: like tobacco, alcohol, presents, and sums of money.
