AP and AC are competing for the most stupid site.

For instance, AC.com will not show the rather obvious YEG-LHR-MUC routing for YEG-MUC. The engine shows four routes via YYZ, one via YUL onto a LH long-haul codeshare, one YEG-YUL-BRU followed by a european codeshare, and the rest use UA longhaul codeshares. There's no failing business model like encouraging your customers to fly on other company's flights.

It's ok. My friends get the hint. They'll book with another airline.
