Friendly crew.

Terrible food and entertainment on the flight to and from Santiago. Felt squizzed like a sardine in the can in the middle row. I will never choose Boening 777 for overnight flights. Transfer in Toronto was confusing. Delayed arrival caused problems in retrieving luggage and made a stressful experience getting to Chicago flight on time - not mentioning sluggish US border check in Toronto. For my next trip, I would rather pick another airline and transfer airport.

Loved crews.

Our plane was delayed for 5 hrs. On top of it, they brought in a smaller plane with 100+ less seating than original one which caused us losing our reserved seating. They refused to give us our seating arrangements up until the boarding time. All the other passengers had boarding tickets but us. So our family couldn’t sit together. I had a super pleasant experience with Air Canada prior to this trip so it made me so sad. On the other hand, crew were fantastic. We missed our connecting flight but they took care of us so I was happy in that sense.

United staff worked with me to book a round-about itinerary on a different airline that got me to my destination within 8 hours of the original flight. Progress announcements were made at regular, predictable intervals.

My flight was cancelled an hour after scheduled takeoff due to mechanical issues. The plane was actually repaired, but the time it took to do so exceeded the flight crew's hours. I understand the practical implications, but in the moment it did feel maddeningly bureaucratic.

none of the flight attendants seemed to be friendly- literally all of them were neutral or slightly rude at best. Not impressed.

We were delayed for several hours. I could’ve and should’ve driven to Toronto because I would’ve made it there a lot quicker. The crew members were rude and clearly unhappy to be working. None of them were accommodating. It was a very unpleasant way to start my trip.

Flight was delayed twice. Luggage was delayed coming off the plane. I assume it was weather related. One piece of our luggage was damaged. Not able to connect to entertainment app.

Typical Air Canada flight. Not great but not horrible (surprisingly)

The entertainment systems were broken on our seats but they did give us a small discount voucher.

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,
