And fuel cost proportion rises with distance so cost advantage of locos narrows.
And I wonder how well the Skavsta, Beauvais, Hahn strategy would work for the very locos on the other side of the pond. Stansted to New York (Providence)? You probably need to be landing at hubs with a decent range of onward connections.
Then there's the frequent flyer points, the fare and purpose mix and the fares down the back of the big boys' planes.
Quite a few barriers to be overcome. Extremely interesting to see how Norwegian gets on.
