After less than a month the C-47 was sold (to Iberia Airlines),[citation needed] allowing BKS to buy two further ex-RAF Dakotas.

For a couple of years BKS flew charters and freight, until 1953 when it had permission for scheduled services between Newcastle, the Isle of Man and Jersey.

It operated from 1957 and enabled longer scheduled services to Basel, Belfast, Bilbao, Dublin and Santander.

[8] By the mid-1960s, London Heathrow had become BKS's busiest base with scheduled flights to Leeds/Bradford, Teesside and Newcastle, as well as international services to Bilbao, Biarritz, and Bordeaux.

[11] BKS Air Transport is featured in the biography Behind the Cockpit Door by Arthur Whitlock, a first officer and subsequent captain with the airline for just over two decades.
