From 1947 British European Airways had operated a Helicopter Experiment Unit and five helicopters were ordered from the United States. The unit operated timetabled mail services in East Anglia during 1948 using their Westland-Sikorsky S51s. A scheduled passenger service was operated during 1950 between Cardiff, Wrexham and Liverpool, also utilising the S-51s. In June 1951, BEA introduced helicopter services between Northolt Aerodrome, Hay Mills Rotor Station in Birmingham, and London Heathrow, operated by a pair of S51s. These services were followed in 1954 by a passenger service between Southampton Eastleigh Airport, Heathrow and Northolt, using leased Bristol 171 helicopters. The 1955 passenger service was flown between Birmingham, Heathrow and Gatwick Airport, again with the Bristol 171s. A separate company was formed in 1964 as BEA Helicopters Limited and operated the first service between Penzance and the Scilly Islands on 1 May 1964 with a Sikorsky S-61. The airline later expanded into offshore oil support flights from July 1965. Operations from Aberdeen started in July 1967 and in 1971 from Sumburgh. With the change of name of the parent on 31 March 1974 the airline was renamed British Airways Helicopters. In 1981, the airline bought six Boeing Vertol BV-234 Chinooks for use on the offshore oil support flights. The company was involved in setting up the Airlink high-frequency helicopter shuttle service between Gatwick and Heathrow airports in 1978. It was responsible for engineering and maintenance of the BAA-owned helicopter and for providing the flight crew. Cabin crew were from British Caledonian as was passenger handling at Gatwick. Heathrow handling was by British Airways. In 1986, the airline was sold by British Airways to Robert Maxwell's Maxwell Aviation and renamed British International Helicopters. The successor company still operated the Penzance to Isles of Scilly route forty years after it was first scheduled, until it was cancelled in 2012.
On 11 March 1983 a Sikorsky S-61N crashed in the North Sea, north east of Aberdeen. All crew and passengers were rescued but the helicopter sank and had to be recovered from the sea bed.
On 16 July 1983 a Sikorsky S-61N crashed on approach to St. Mary's, Isles of Scilly with the loss of 19 passengers and one crew member.
On 2 May 1984 a Boeing 234 crashed in the East Shetland Basin of the North Sea, north west of the Cormorant Alpha Rig. All crew and passengers were rescued by other helicopters and boats. Although not damaged in the accident the helicopter sank after 85 minutes. The aircraft was recovered for post accident investigation and later refurbished to fly again.
