The trip was generally as expected. This was the first trip our family of four had taken since before the baggage fees had become common. I chose this airline for its price. For a short flight, this was very nice. It is best to know your luggage needs before you purchase. It was helpful to see the total round trip pricing as well.

Seats are more uncomfortable than other airlines. No fee coffee or water or anything. Tiny little seat back trays are borderline useless

That they were upfront with the fact that they charge for everything

NEVER AGAIN! My fight was canceled 6 hours before my departure, due to “air craft congestion” (whatever that means). They were unable to get me on a new flight until two and a half days later. I ended up booking with another (more reliable) airline because it was cheaper than taking 2 days off of work, staying in a hotel, eating out, rearranging child care, paying for extra parking at the airport... SO DISSAPOINTING. It put a huge black spot on my otherwise awesome weekend, among me have to scramble to get everything worked out while trying to get home.

No one told us they wanted everyone with a roller carry-on to.check their bags. An attendant told my sister that her bag needed to be checked. We did not receive this notification until we were at the gate, boarding.

55.00 for a carry on bag?? Are you kidding me? If I had known that when I bought the tickets of course I wouldn't have bought the tickets. For another hundred dollars I could have bought a ticket From Alaska flown in comfort and had free water !!! Instead I had to use that 100.00 for carry on bags! I hate you guys! You're the biggest rip off. I fly an average 3 times a year. I will never fly Spirit and I will tell everyone on all social media not to fly with spirit unless they enjoy getting raped!!!

Connection flight from LAX to Seattle was dropped off of booking completely. When Delta was able to fix the changes in Sydney Australia they put my husbands ticket as a standby instead of putting him in an assigned seat and reported that they couldn't fix it that we would have to wait and get to LAX before the changes could be made again. There was a one and a half hour flight delay from LAX to Seattle. From Sydney Australia to LAX entertainment system didn't work the whole entire flight, they were screaming children the entire flight, and Delta had double booked seats on several different people. There were no apologies and no compensation for any of the incidences.

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.
