The flight attendant knows it is important for the passengers to fill out the customs declaration and immigration cards correctly. So they watch to see if any passengers are having trouble and then offer to help them. Many countries require arriving travelers to fill out “immigration cards” regardless of whether the travelers intend to stay or live in the country or are just tourists on a visit. These cards are also called “arrival” or “disembarkation” cards. Immigration cards ask for information about the passengers and are important for a country’ s tourism department, which uses this information in planning facilities for tourists. The tourism industry does not consist of one big business. It is many businesses that provide many things for tourists. A hotel is an accommodations facility, a place where a traveler can eat or sleep. A restaurant is also an accommodations facility. Airports are travel facilities.
