Brymon was the first, they did all the hard work including the first landing at Canary Wharf early eighties with the dash 7. Capt Harry Gee in command.
On start up of the first commercial flights the service operated PLH-LCY- CDG then several CDG rotations, the aircraft then operated back to PLH in the evening for routine maintenance. The PLH-LCY-PLH sectors didn't last long, low pax numbers, therefore engineering came up with a maintenance plan that did not require the aircraft to return to PLH every night.
