The airline started operations during March 1964 with one Lockheed Constellation and three more were acquired in August 1965. The airline was awarded an "E" Licence in January 1964 to carry out non-scheduled all-freight operations from the UKs Air Transport Licensing Board. An application in February 1965 for permission to operate scheduled all-cargo services on a London-Middle East-Far East-Australia route was rejected by the ATLB in May 1965. ACE carried out worldwide ad-hoc charters from London Gatwick Airport. During 1965 some sub-charter freight flights were flown within Europe for British European Airways. A large number of regular charters were operated on British Ministry of Defence of contracts to the Middle and Far East. Routes flown were particularly RAF Lyneham to Malta, Cyprus, RAF El Adem and onwards to Singapore. After leasing a Douglas DC-4, this was bought and another DC-4 acquired. During the 1966 UK docks strike many freight charters were flown from Southend and Gatwick to Amsterdam, Paris and Rotterdam. In May 1966, for example, G-ALAL flew up to five return flights a day from Southend to Rotterdam. Freight charters were operated into Heathrow for Aer Lingus, Swissair and United Arab Airlines. On 23 September 1966, the airline was placed in liquidation after having run up large debts for fuel, and the aircraft fleet was stored until sold.
ACE Scotland
In December 1965 a subsidiary companyACE Scotland was formed. Revenue earning operations commenced on 16 July 1966 with an inclusive tour holiday flight from the ACE Scotland base at Abbotsinch Glasgow to Barcelona and Palma. The airline was equipped with one ex-South African Airways L-749A Constellation. Thereafter regular flights were made from Glasgow to other European destinations including Rome and other flights were made from Gatwick. Ad hoc charter flights took the Constellation to Athens, Jeddah and Tours. The airline was forced to cease operations on 23 September 1966 on the liquidation of the parent company. The last commercial passenger service was flown on 10 September 1966 from Palma to Abbotsinch, followed by the last freight charter from Gatwick to Düsseldorf and Heathrow on 11 September 1966.
