Interesting effect of APD etc.. on Ireland v UK fares. Checked out Dublin and Glasgow flights to St Johns for 4th - 7th May '16:
Result = Dublin return £270, Glasgow return £440 - Guess NCL would, if operated be therefore higher than Glasgow, making connections via other hubs quite a bit cheaper, should Westjet ever decide to start a NCL service. Similarto United this year, high fares would push prospective passengers to use other connnections - Fares to Toronto & beyond are even higher
