I am flying from YEG to SFO tomorrow morning (flight UA 6421). I bought my ticket via the Air Canada website and on my itinerary it says the baggage allowance is first and second bags complimentary. The flight is being operated by United Express/Skywest. When I checked in this morning on the United site, I indicated that I would have 1 checked bag and it said it would be $22 for the first checked bag. Which is correct? I am flying business class.
