At airports, there are many different types of conveyance available to travelers. These include trams, limousines, taxis, cabs, sleds, cars, and rafts. Trams are large vehicles that run on tracks and are used to transport large numbers of people. Limousines are luxury cars that are often used for special occasions. Taxis are cars that can be hired to take passengers from one place to another. Cabs are similar to taxis but are usually cheaper. Sleds are vehicles that are pulled by horses or dogs and are used mainly in cold climates. Cars are the most common form of transportation and can be rented or owned. Rafts are boats that are used to cross rivers or other bodies of water. All of these forms of transportation can be found at airports and can be used to get to and from the airport.
