The 'cross-country' was known as the Link City, which I think was even painted on one of the HS748's. Bournemouth (i.e. Hurn in proper language) had 2 based 748's that stayed overnight. I thought one was for the Jersey/Guernsey routes and the other for the Link City route.
When the Comet at Hurn in 1979/1980, Bath Travel sold tickets for the positioning flight back to Gatwick for £8 each. The aircraft was G-BDIU and the pilots did an amazing take-off roll starting from turning onto the runway, with what appeared to be a near vertical climb-out! At Gatwick they finished with an overshoot before landing. What an amazing £8 worth.
I also flew on B727's G-BAFZ and and G-BAJW when I did 2 ski trips to Clermont-Ferrand. I did a cockpit visit on one trip and there were 5 flight deck crew.
Certainly an oddball airline and always something interesting to see. Like the Fiji Airways 748 on the Channel Islands route one day! (DQ-FAL, later G-BIUV).
