YYC is a nice airport. I have found I like Canadian's more then Americans when it come to air travel.

LAX is not a convenient airport at all.

seat and seating was nice, boarding was efficient, movies okay

while the dinner was okay, the stromboli which came as a snack of sorts was terrible and caused me to be "on the run" for the next 12 hours. the last five hours of the flight and then at home were awful

The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!

The gentleman at the gate was super helpful and helped us check our bags at the gate.

Zero leg room. Zero arm room. The entertainment system did not function. No food for such a long flight unless you pay more then the food is actually worth.

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

I know this isn’t Kayak’s issue but American Airlines literally forgot to put fuel into the plane. We were delayed for over an hour and luckily I made my connection in Charlotte but only because they held the flight and it was not full. Had it been full I would have lost my seat.

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

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.
