Surely you're looking at this the wrong way round? Guernsey should be marketing destination Guernsey, surely? With European holidays becoming more and more expensive there is probably going to be a once in a generation opportunity for destinations like Guernsey to fill their boots as long as they are prepared to invest in the resources/marketing/infrastructure to service an influx of inbound tourism. Part of that will be runways that can take A220/319/320/B737 aircraft. Unfortunately GR have proven themselves not fit for purpose despite some protectionism so let them go and let someone more efficient take over. Lost jobs will quickly be replaced with some imagination from the Guernsey state.
