lots of Irish in Canada now so would expect it to be well used.
I doubt it, it's incredibly seasonal and low yield. There's a reason Air Canada use the "Three Amigos" B767 fleet to DUB, ATH and BCN in summer. You won't see those aircraft at any mainline AC station in Europe, this is a summer holiday route, peak season only. TS would have had a single weekly flight, much like GLA over the winter,that's how small the market gets. If this new loco gets off the ground, I cannot believe they would be anything more than weekly over the winter, it's just never been done in that market, in
GOOD times.
This appears to be more like a replacement for the BMI STAR feed over Heathrow and as for the airline within an airline concept, well their track record is poor.
