It would be very suprising that TS would not be allowed to fly to Mexico from the US because of safety/maintenance issues. They already do from virtually everywhere in Canada and those flights have been operating on schedule. Everyone in the current economic environment in North America needs a little boost and I don't see why the Mexican gov. would not allow of plane full of consumers that are going to spend big $$$ in their country.
Just my opinion, I would certainly be interested to read the article If the newspaper has a website.
