Everything went smoothly and efficiently. I think they offered soft drinks or snacks but I was asleep.

The flight was just fine

The main problem was that when I checked in online, I tried to add on more piece of luggage—for a total of 2 checked in. But the computer ended up totaling it as 3 pieces of luggage. There seemed to be no way to change this online. So I asked them to change it when I got to the airport, but they wouldn’t. What was done couldn’t be changed. Another issue I have is with this review questionnaire. They are questions for rating the food and entertainment which the airlines don’t provide anymore. These should be removed from the survey. They should, however, ask how was the process of making the reservation, check-in, and customer service in general. Both from the airline, and any third party service like kayak or kiwi. I’m not satisfied with kiwi as they were closed when I tried to call them. So I had to just fend for myself and spend money needlessly.

swift flight so that we could get off of the plane quicker.

getting in and out of the seat was awful. especially when the seat in front is reclined. the armrest on the aisle seat should be able to move up as the others in the row did. the metal underneath the armrest is pretty sharp and jagged, scraped my palm as i was trying to get the seatbelt to buckle.

No food choices. First airline I’ve been on that only has snacks . Second the $50 baggage fee is outrageous. Third there isn’t any WiFi so we’re stuck in the air with no type of communication with the world. Spirit charges way to much money to not be up to part. Hey it together Spirit .

$55 carry on fee is insane and I was surprised because I believed a carry on would be included. But i discovered many little hidden fees. The leg room was adequate but the seats were hard and uncomfortable.

Airport waiting area was very nice with lots of different seating options. The boarding went very quickly, but that was because the flight was mostly empty. Can't believe how expensive the luggage was. I guess that is why the ticket is less expensive.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
