Didn't really mean to pick on any particular route but just pointing out that whilst there is good choice of routes and service in the summer there is very little to be had in the winter. Sadly that doesn't cut it for business. I suspect the lack of choice in November placed me in the position of ending up flying stateside in economy when I (or rather the client) was prepared to pay for Business....but it wasn't available. Not good for business if you'll pardon the pun.
Also both TCX and VS tend to reserve a lot of their capacity in the premium cabins for their 'holiday' customers thus restricting the available space for pure airline customers.
Worth remembering that until 2016 we had no service at all to the US West Coast.
There still isn't for most of the year
