The flight was rescheduled to take off three hours from original takeoff. Because it was too late for arriving time in Chicago we decide to book another flight for the following morning. I want to mention that this is happening second time we the same company . Very disappointed with spirit airlines!!!

Pleasant staff

My husband and I chose seats together when the tickets were purchased and when we received or boarding passes they had been changed, separating us. My 6 foot 200 lb husband ended up against the window in a row with 2 women that were both well over 250 lbs and I was seated with strangers. No free movie as there was on the trip to Texas

Not a single part has a positive remark

Well - this partner of westjet was terrible. The amount of re direction to get to the final terminal was absurd .. that's just my venting My real problem is that then "crew" or team that represent s the American Airlines / compass part was just useless. A hand full of people - myself included didn't get a chance to board the plane as they didn't make any announcements. Beyond disappointing. When you check in they take your cell phone "in case " well no call no txt no nothing. It was a joke the level of service No apologies or anything just a group of any tired patrons getting the worst customer experience. I'll never EVER book a flight that has anything to do with American Airlines or its partners

Ok, I get that I checked in on the first half of the round-trip too late to get a cheaper rate for checked baggage, why I charged the increased amount for return flight made no sense. Also it would have been nice to know that you needed to check in more than 24 hours in advance to avoid the baggage surcharge. No party to this transaction bothered to tell you.

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,
