Donaldson International Airways (a trading name of Donaldson Line (Air Services) Limited) was formed in 1968 to provide inclusive tour and charter flights for Mercury Air Holidays of Glasgow.

These aircraft were also operated on charter flights from other major UK Airports including Manchester.

Donaldson Airways started charter flights across the North Atlantic with the delivery of two Boeing 707 aircraft in 1971.

Three of the 707s were fitted with a cargo door to enable the airline to operate both passenger and freight charters.
