YYZ was a long standing route for Belfast and can easily be so again,
And for Exeter, Cardiff, Newcastle, Leeds, Birmingham and Edinburgh, all gone and closed. The market has changed beyond recognition since the simpler days of Wardair, Worldways and Air Transat. The house of mouse might work on long haul but not sure Canada will come back to non hub airports like BFS. Air Canada Rouge is not so much a visiting family market but an inbound tourism market which is why they're having a crack at EDI and DUB.
