If I open a totally clean browser, it (
www.aircanada.com) lands on the classic page after asking language/country... so perhaps it's some redirect thing going on... As soon as I hit beta.aircanada.com once, I get stuck in beta with no "user-friendly" method of returning to classic.
Still, I'm glad I'm looking at the new "features" or "limitations" of the new site. For instance, no clear way to change the ff number attached to PNR.
Edit: Actually, at the bottom of most pages, I now get this... which appears to undo the redirect to beta.aircanada.com
