O'Hare airport is too much of a confusing adventure. You get off the plane and you have to find the certain gate you need then proceed to the lower level which is a long,long,long walk then trying to figure out where your luggage is, but if you have the app of whatever plane you are using it is much easier. Does everyone know about this? I didn't.

There was a 3 1/2 hour delay, in which we had boarded the plane. And just prior to departing we were informed of an issue with plane that had just been noticed and that we'd be delayed for ten minutes, then were told another thirty minutes, then another hour. Finally we were told to disembark from the plane and go take our carry on bags with us. We finally boarded the plane and took off at 8:55 pm after we were scheduled for a 5:25 pm departure.

The flight attendants passed my row and didn’t offer drinks. When I asked 10 minutes later the FA later they said they were done with beverage service. Also I specifically picked a seat in the last row when i bought my ticket. When i got to the gate the agent took my ticket and crossed off the seat I chose online. She wrote in seat 17B because they gave me seat away without asking me.

It would take little effort for the flight attendant to say which terminal the baggage claim is. If she can say the carousel number, she can say the terminal number. Half the flight went to the wrong baggage claim and had to wait in the heat for the shuttle in order to get to the right one.

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,
