Flights to the Maldives are served by the national airline Maldivian. The main airlines flying to Malé are British Airways, Qatar Airways, Emirates and Sri Lankan. Due to the distance involved, flights year-round are fairly expensive, but they are especially high during Christmas and the winter months. Internal flights in the Maldives are operated by Maldivian, linking Malé with the provincial centres. There are also two seaplane companies operating seaplane transfers from Malé airport to individual resorts. These are Trans Maldivian Airways and Maldivian Air Taxi. There are only roads in Malé and a couple of other islands where there are small tarmaced strips. Overland transport on resort islands is by golf buggy. Visitors generally remain on their resort island for the duration of their stay, although island-hopping trips by dhoni charters are widely available. High-speed boats usually meet arrivals at the airport, supplied by the resort they are booked with, and boats are available for hire at the ferry counter near the jetty area. The speedboats connect the airport with North and South Malé Atolls.
