Calgary to Charlottetown, PEI - $401 roundtrip after tax
It's not quite as exciting as Air Canada's highly unusual price drop to Halifax yesterday, but it looks like they've significantly dropped some of their June fares from YYC to YYG today.
Try June 18 to 25 for example on AirCanada.com and this is what you'll see:
Unfortunately there's no longer a 15% off promo code to bring it down any further. But considering that fares to PEI usually hover around $700ish these days, it's already a true 40% discount.
Also similar to yesterday, the reverse route is available for the same price, so if you have friends/family in PEI that want to come out west, let 'em know.
