ALM Antillean Airlines (Dutch: Antilliaanse Luchtvaart Maatschappij), and later Air ALM, was the main airline of the Netherlands Antilles between its foundation in 1964 and its shut-down in 2001, operating out of Aruba, Bonaire, and Curaçao. It was based at Hato International Airport.^[1][2]

ALM Antillean Airlines was founded on August 1, 1964, by the conversion from KLM West-Indisch Bedrijf (West Indies Division). ALM operated as a part of KLM Royal Dutch Airlines, who wanted to make Curaçao the hub for their American operations and to provide an American link between the Far East and Europe. KLM did this with the flight of the Snip^{[clarification needed]}. ALM started with three Convair 340s and served seven destinations. In addition to the airline business, ALM also provided catering and airline servicing for other companies using the Curaçao and Aruba airports. Its main destinations were Aruba, Bonaire, St Maarten, St Kitts, Maracaibo, Barranquilla and Caracas. Due to the surge in tourism, ALM quickly grew, and the Convairs were replaced by two Douglas DC-9-15s jets (ex KLM) and two brand new turboprop Fokker F27-500 series. New destinations were added, and an ex Viasa DC-9 was also added to the fleet.

The period between 1968 and 1969 was crucial for ALM. By January 1, 1969, the Antillean government took a 96% share from KLM and ALM became a state-owned company. An ex-KLM Douglas DC-8 was chartered to further use the booming tourist industry. Now ALM was able to fly directly to New York and Miami. Later on, Panama and Costa Rica were added as destinations. The New York to St Maarten route (1970 to 1973) was flown with a chartered Boeing 727-100 provided by Braniff International Airlines and also at one point with an Overseas National Airways (ONA) McDonnell Douglas DC-9-30.

The Fokker F-27s were replaced by a third DC-9-15 also from KLM and ALM became an all-jet passenger airline for a short time. During this time in August 1972, a Douglas DC-6B was purchased for the cargo routes. Windward Islands' Winair was acquired, with its fleet of turboprop, STOL capable de Havilland Canada DHC-6 Twin Otter (series 300 aircraft), by the Antillean government. It became apparent that on the short flights to Aruba and Bonaire, the DC-9 jet was not cost-effective. A temporary solution was found in the shape of two Twin Otter 100 series. For a while, ALM Twin Otter flights between Aruba-Bonaire-Curaçao were labeled ABC Commuter. After a bumpy start the Twin Otter became a success with the passengers and two further machines (series 300) were added. In the years 1973 through 1978, ALM made a total profit of ANG14.3M. Their raison d'être was to maintain airways between the islands of the Netherlands Antilles, and to promote tourist trade by providing transport.

In 1975, ALM replaced its older DC-9s with the new McDonnell Douglas DC-9-32 series, significantly increasing seating capacity. Two years later, a Boeing 727 was added for additional routes to Chicago, Cleveland, Detroit, and New York, which were mostly operated as charter flights. During this period ALM grew rapidly and its number of personnel doubled in 1977. A year later, a bilateral agreement between the Antillean government and the US was reached whereby ALM was allowed to take over the routes from KLM to the USA. To cope with the demand two Douglas DC-8-53 jets were leased from Rosenbalm Aviation. Additionally, the Twin Otters were replaced by Short SD-330 commuter turboprop aircraft. In 1978, KLM restarted extensive cooperation with ALM. Two DC-8s were brought into the fleet and served the route Curaçao-New York JFK, where KLM handled the ground services. KLM was still hoping and trying to build a hub with ALM. KLM flights from Curaçao-Amsterdam often had at least an ALM cabin crew on board in those years.

1979 was a turning point for ALM. The low point of the oil prices coupled with slow tourist figures and the devaluation of the Venezuelan currency, brought ALM into trouble. Additionally, ALM had to deal with competing businesses from Eastern Air Lines and American Airlines on competing routes. The DC-8 flights were halted and the newly arrived Short 330s were sold off. During 1980 the Boeing 727 and Beech Queen Air left the company and ALM concentrated on its fleet of four DC-9-32s.

In 1982, ALM decided to replace some of its DC-9s with two McDonnell Douglas MD-80 jetliners, which were leased from Curaçao Aircraft Leasing Company. A third example was later purchased from Continental Airlines. With business slowly improving, ALM was able to purchase additional airplanes which included the purchase of two elderly Fairchild Hiller FH-227 turboprops from Delta Air Transport for the short-haul routes.

ALM previously served the following destinations during its existence:^{[citation needed]}

Over the years, ALM operated the following aircraft types:^[4]

• ALM Flight 980: Operated via a wet lease by Overseas National Airways (ONA), was a scheduled flight from John F. Kennedy International Airport in New York City to Princess Juliana International Airport on St. Maarten. On May 2, 1970, the McDonnell Douglas DC-9-30 (registered N935F) operating the flight ran out of fuel after several unsuccessful landing attempts due to weather conditions, resulting in a water landing and ditching in the Caribbean Sea 48 km (30 mi) off St. Croix and the death of 23 of the 63 people on board.^[5]
