You should see GR's loads from Gatwick... pretty darn good I'd say.
I have done at first hand, however they continue to subsidise losses, underwritten by the States of Guernsey Government. It's not a wholly commercial operation, unlike flybe and BA. Great airline though and I am not arguing that subsidies in this case are wrong, just saying good loads at GR does not equate to profits for BA if they launch Guernsey.
