Wait until this pricing tactic is reversed just like it was reversed by Europe.. The charges will be refunded and AC and AE may experience a huge chargeback which IMO is 100% deserved.
I often check multiple airlines just for curiousity on
www.expedia.ca and price out all flights and see if the ones that I frequent is half decent. If so, book, regardless of what the price is.. and often
www.expedia.ca includes price, and all fees, so sort of an apples to apples look, except of course baggage fees.. Make those adjustments and you've got a clear picture.
