In Maldives, there are three main ways to travel between islands: by domestic flight, by seaplane, or by boat. For several years there were two seaplane companies operating: TMA (Trans Maldivian Airways) and Maldivian Air Taxi, but these merged in 2013 under the name TMA. The seaplane fleet is entirely made up of DHC-6 Twin Otters. There is also another airline, Flyme, which operates using ATR planes to domestic airports, principally Maamigili, Dharavandhoo and some others. Manta Air begins its first scheduled seaplane service. Its seaplane fleet is made up of DHC-6 Twin Otter aircraft. In addition to the seaplane service, Manta Air utilizes ATR 72–600 aircraft to operate domestic flights to Dhaalu Airport, Dharavandhoo Airport and Kooddoo Airport from the main Velana International Airport. Depending on the distance of the destination island from the airport, resorts organise speedboat transfers or seaplane flights directly to the resort island jetty for their guests. Several daily flights operate from Velana International Airport to the 12 domestic and international airports in the country. Scheduled ferries also operate from Malé to many of the atolls. The traditional Maldivian boat is called a dhoni. Speedboats and seaplanes tend to be more expensive, while travel by dhoni, although slower, is relatively cheaper and convenient.
