air Uk operated the GCI-LHR route from April 1980 until around the end of 1997, when they pulled out of the route. Not had a Guernsey Heathrow service since and probably never will.Used heralds until about 1983 then used F27s until 1988 then used the BAE 146 for a few years and then went back to using F27s and finally Fokker 50.
