In flight crew was cordial, warm, professional

Everything else was a sh*tshow: bad information, confused and angry employees, flight was 7-hours late

Mediocre 3.0

Service was awful. Delayed for more than 8hrs without an explanation of what type of maintenance issues were happening. Never given a straight answer as to what was happening. Food vouchers were only offered after the airport restaurants had closed. Once the plane was finished the crew had timed out and we could not leave till the following afternoon. Ended up being put up in a hotel for the night and lost an entire day of our weekend get away. Poor contingency planning on frontiers part. There was no reason

Okay 4.0

The crew was really nice.

So many delays. My flight was eventually cancelled on Friday and was rescheduled for Saturday. The Saturday flight was delayed. All in all, i wasted a vacation day on Friday, I paid for a hotel in Denver for Friday night that I was not able to get refunded, I missed out on a day in Denver. It was a huge bummer.

Easy flight with good price.

No one takes cash anymore! Have to pay for all snacks! Not alot of room for broad shoulders.

if you have a hard engagement that you have to make, i hate to say it, but use a bigger airline. These guys are not dependable nyc -> miami. Have had 2 flights cancelled and delayed over 6 hours in the last 6 months. Only one scheduled flight everyday. If you can risk it, fine, but otherwise not worth it.

Everything was good

One Stu artist who was a older women she was very grumpy, there was little to no turbulence the whole flight and if you got up to go to the washroom and we’re waiting and seatbelt light came on she would make u sit down immediately even if it wasn’t that rough, she made a girl wait for the washroom for 45. Minutes was kinda pathetic, when she was on her shift break not one person had a issue with any of the other flight attendants only her

The extra $50 seats were roomy.

Flight was delayed and no one knew why!... Plane had been sitting ready at the airport for hours. Novice flight attendants, they each picked on different things others missed just before them. No consistency, seats left reclined during takeoff and landing for example. One way there was drink service once even though it was a smooth flight and the return had drink service twice even though it was bumpier! Entertainment does NOT work on androids, it is NOT the AirCanada app they tell you to download prior to the flight, it's an AirCanadaRouge.pk file that needs to be downloaded in flight! Which means we're stuck paying for the iPad and of course only with cc because there's no wifi for debit cards.... AC needs to stop this insanely mediocre and yet expensive monopoly.

I think the air quality on the flight from Toronto to Seoul was bad. I felt really neaseous for most of that flight and thought I would be sick on the landing. the illness went away completely once I landed and I didn’t experience it on the Asiana flight from Seoul to Phuket

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.
