United and WestJet are offering round-trip flights from Houston (IAH) to Calgary, Canada (YYC) for $275-$299, NONSTOP. Flights from November to the start of April’2016. Fare is reversible. Holiday Blackouts apply.
WestJet opened their new route between Calgary and Houston two weeks ago, on August 8th. Prices will probably stay low while United and WestJet fight for market share.
Note: Of all the booking sites, Travelocity and Expedia seem to price this at $268 instead of $299. You can save a bit of extra cash by using them instead of any other site.
