There was a 30 min. delay. The waiting area was crowed and the audio system poor. The speaker's speech was so garbled it was hard to decipher what was being said about the delay and boarding. The flight itself was fine with very friendly crew.

Boarding and flight were fairly smooth, the crew were friendly and the seats were comfortable.

Told that due to turbulence, no cart service would be available. There didn't seem to be a whole lot of turbulence that would prevent cart service. We did get a bag of terra chips and a small water.

United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit.

I liked the fact that even though we board our flights 30 minutes later we got to DC on schedule. The pilot took into consideration that there were people that needed to get to their next flight. I'm sure it was appreciated

no food or entertainment but then again the flight was only 50 minutes

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
