Flight attendants were inconsiderate and rude about using the lavatory. Boarding process felt disorganized and chaotic and the planed ended up needing maintenance. Additionally the smell of gasoline as the flight was taking off seems like it's actually a serious health risk no one is addressing.

Spirit Airlines must make all their money on carry-on charges. Although I measured the dimension of my bag, it was slightly outside of fitting in their metal box at check-in, which cost over $50 when it still for in overhead no issues.

Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants.

Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do..

The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful.

We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner.

We have been on 6 flights over the last 8 days, all with Delta and we have already started telling people how wonderful the service was. Sherry on this last flight was amazing, working so hard all by herself as our flight attendant. We were very impressed. And the pilots all came out to say goodbye and thank you. All very nice...esp for me who needed some wheelchair assistance. We will certainly fly with you again in the future.

The corner cutting is starting to cross a line.

I didn't pay to request a certain seat, so I was in the middle seat of the last isle for each flight. The "free" entertainment was ads to purchase entertainment.

This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane. When my flight was canceled initially no one informed me that my return ticket would be canceled which I specifically asked about. I hope never to fly united again. The day to day staff at ohare and on flight were good and courteous.

Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights.

Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours.

Okay 5.6

The boarding process is horrible. You have to stand in lines that disrupt the other people trying to navigate through the airport.

Mediocre 2.0

Flight attendants were inconsiderate and rude about using the lavatory. Boarding process felt disorganized and chaotic and the planed ended up needing maintenance. Additionally the smell of gasoline as the flight was taking off seems like it's actually a serious health risk no one is addressing.

I will try to avoid Ohare in the future. Long wait to take off. Had to RUN to make the connection. Again.

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.
