Well despite how far it's fallen, it's still up on Air Canada. Their business model is running flights as a cover for taking as much government funding as they can get.
When I was still living in Canada and my now wife was here in the UK, we discovered that booking with Air Canada was $100-$300 cheaper in the UK than in Canada.
I have a friend named Fidel Castro. To fly from Canada to Costa Rica, his flight cannot have a connecting in the US. Is costly.
Apparently that name is not that uncommon for South Americans born shortly after the Cuban Revolution. First name that is. He just unlucky to also be a Castro. No relation.
You'd think that once someone has been dead for nearly seven years, they'd be less of a priority. And anyone not actually dead would be highly unlikely to be traveling under their own name.
They absolutely know he is not Fidel Castro but rules be the rules. I think now you can get exceptions but believe you need to do prior to travel and is a pain in the ass.
Off topic, my brother in law and his wife were in Cuba the week he died. All the bars shut down.
