When you arrive at an airport, the departures board will show you the flight numbers (e.g. BA735), departure times (e.g. 08.40), and destinations. At check-in / the check-in desk, someone will check your ticket and weigh your luggage. If it is more than, for example, 20 kilograms, you will have to pay excess baggage. You can take your hand luggage with you on the aircraft . You also get your boarding card and then you can go through passport control, where someone checks your passport, and into the departure lounge, where you can buy things in the duty-free shop, e.g. cigarettes and perfume. Shortly before take-off , you go to the place where you get on the plane, e.g. Gate 3 or Gate 5. When you board the plane, you can put your hand luggage in a small cupboard above your seat called an overhead locker. You then have to fasten your seat belt. If there are no delays , the plane moves slowly to the runway, then it takes off.
