Nolinor seem to be reasonably well orgainsed for their current market & i wish them well for what could reasonably described as a "courageous" decision at this time & state of the aviation market. Perhaps they see themselves being able to take up some or all of Transat's market assuming the deal with Big Red grinds it's way to a unifying conclusion, as there seems to be some degree of overlap between AC/Rouge & AT's routemaps.
On a personal note, I cannot help but notice that AT's ticket prices seem to have crept upwards towards the costs charged by AC/Rouge, and honestly I've never seen a great deal of difference between the mainline & "low cost" fares for broadly the same travel time from nation to nation, so there should be scope for Nolinor there too.
