So no more Edinburgh to Newburgh Stewart on 737s then? Maybe someone else will pick up this vast, now untapped market.
LOL, hasn't Ryanair toyed with the idea of transatlantic service? I honestly could see them serving the U.S. via cheap airports like BWI, ISP, MHT, PVD and/or SWF that could be easily reached from smaller European airports like EDI and SNN. Thanks to its geography, couldn't EDI function as a dirt cheap gateway to Europe? Norwegian's p2p 737 services never made sense, but an established European operator like Ryanair or easyJet might be able to connect folks through places like EDI or draw upon local FFer bases...
The disadvantage of Edinburgh is that it's in the UK and therefor subject to the British APD. This isn't so much a problem on short haul within Europe as the APD for such short flights is negligible, but TATL flights are longer and therefor subject to a higher APD. That makes they can't offer the fares as low as they want them to be.
It makes more sense flying to those destinations from Ireland which doesn't have any aviation tax. Dublin is already one of their largest bases, they could offer those flights out of there. In fact, when Norwegian flew to those destinations only their flights out of Dublin had good load factors. Flights from Edinburgh to the same destinations on the same days were always more expensive than flights from Dublin, the difference is in the APD.
So while I mostly agree with your statement, I think Dublin would be the dirt cheap gateway to Europe instead of Edinburgh. Tax reasons.
Ryanair officially doesn't offer connecting flights, however they do offer "arranged self-transfers". The total fare is just the fare of both flights added up, officially it's two separate bookings and you need to check in for each flight individually. In the case of Dublin, where there's no aviation tax, this is a benefit.
