I visited Guernsey and then Alderney in September, travelling with Flybe NCL-SOU-GCI, and back ACI-SOU with Aurigny and NCL-SOU with Flybe, travelling between the islands on the BumbleBee that only operates two days a week, during summer. Alderney's a beautiful island, and I would love to go back, but with the fares charged between ACI and GCI by Aurigny I would have to think twice, to be honest.
I'm only one punter out of many, of course, but I can't help thinking that cutting ACI-SOU service would be a massive blow to the island's visitor industry.
