Jenny and I thought about taking a trip to London, England, because Air Canada is offering a round-trip special of $418 per person. I knew there would be a few hidden additional fees, but this is ridiculous. Check out the breakdown: $418 ticket price. Advertised ticket price for two: $832. $805 in hidden fees. Actual price: $1611. But at least we only have to pay $1.95 in taxes.
