10 Dme Arc
Going at some of the fares for the route I think what you heard is wrong.
Looking at the airlines other routes it looks like a flyGlobespan thing to stop enroute. You only have to look at Stansted to Toronto this summer with every flight having a stop, the Glasgow to Boston is the same as the LPL/JFK in having a stop in Knock on some days. Even some of its European routes are having stops.
