The origins of Bahrain's international airport dates to 1927 when a chartered flight to Bahrain landed. The first scheduled commercial airliner to arrive in Bahrain, in 1932, was a flight from London to Delhi operated on a Handley Page H.P.42 aircraft named Hannibal. The H.P.42 carried only 24 passengers, and the flight from London had taken several days of flying at speeds of 100 miles per hour. Through this regularly scheduled service, Bahrain became established as one of the Persian Gulf's first international airports as well as one of the busiest airports in the Middle East. During World War II, the airport was used by the United States Army Air Forces Air Transport Command Central African Wing, being designated as Station # 13. It functioned as a stopover en route to Abadan Airport, Iran or Sharjah Airport, in present-day UAE on the Karachi-Cairo route. From 1943 until Bahrain's independence in December 1971, the Royal Air Force maintained a military installation at the airfield known initially as RAF Bahrain and from 1963 as RAF Muharraq. The majority of these facilities were later acquired by the Bahraini flag carrier airline, Gulf Air, while a small portion continues to be utilized by the U.S. Navy as Aviation Support Unit (ASU) Bahrain. In 1936, the operation of H.P.42 aircraft from London to India via Bahrain had been stepped up to a twice-weekly frequency. In 1937, Bahrain saw the regular service of the Empire sea planes. The landing strip of these giants on the water was from where the marina club is located in Mina Salman today. From the 1950s, BOAC operated several services a week through Bahrain. These included weekly services to Karachi, Singapore, Hong Kong and three times a week to Sydney. 1950 was a significant year not only for Muharraq as an international airport, but also for Bahrain's commercial aviation history. In this year, a new local airline, Gulf Aviation Company, was formed – the forerunner of Gulf Air. The company started with only one aircraft, a second-hand Anson Mark II, which was used initially on services to Dhahran. However, within two years, the fleet had expanded to four de Havilland aircraft and DC-3s for use on a steadily growing network in the Persian Gulf. This established Bahrain on an international stage. It was easily the most modern and advanced airport in the Persian Gulf with a good runway, control tower, lighting, communication facilities and even restaurants. It began to attract other carriers such as Middle East Airlines, Air India, Air Ceylon and Iran Air – mostly operating Dakotas. In December 1961, a new passenger terminal opened at the airport. During 1970–1971, RAF Muharraq was scaled back and eventually closed. In December 1971, the airport opened new passenger facilities, which included a wide area that could accommodate four 747 aircraft. In 1976, the airport marked another significant first with the inauguration of supersonic flights, which saw the start-up of regular BA Concorde service between London and Bahrain. Pan Am introduced direct flights to New York in December 1976. It operated the route with Boeing 747SPs. In the 1980s and 1990s, major facelifts took place and several major airline companies made the airport a destination. In 1994, a US$100 million terminal was inaugurated which boosted the airport's maximum capacity to 10 million passengers a year. In July 1994, Gulf Air started nonstop service to New York on Airbus A340s. Due to the length of the route, westbound flights occasionally had to make a refuelling stop. In 2008, the airport was placed under the management of the newly created Bahrain Airport Company, which falls under the umbrella of the Gulf Air Holding Company, which in turn is owned by Mumtalakat, Bahrain's sovereign wealth fund. On 8 October 2009, it was announced that BHD 1.8 billion expansion of Bahrain International Airport will start in 2010.
