Three hours delay. I paid for a upgrade to first class. But because of the flight change i didn't get to keep my upgrade and I had to beg for a refund. I have had two trips in the past 5 days and all flights have been anywhere from 1 to 3 hours late. Worst experience with AA I have had in a long time.

I don't have a problem with a flight being delayed for any reason. That is simply one of the hazards of flying. However, the PIT->ORD flight was delayed multiple times for unknown reasons. If the airline would have given a realistic timetable, customers could have managed their time much easier. Instead, United Airlines kept delaying takeoff for 15-20 minutes, multiple times. When they finally get the customers into the boarding process, they act like they're doing you a favor. Poorly managed, customers manipulated.

My father is 89 and our whole family went to see him off. My husband, 3 children and myself. When I went to the ticket gate to check him in, the ladies did not issue a family pass to us. They said only 1 member of our family can go with him to wheel him to the gate. So my husband went since my father had 2 carry on luggage plus he wheeled my father. So the ladies were not very understanding. At that age I do hope he makes it back in 6 months for us all to see him again! We've been issued passes before and their only excuse was it was busy which it was not at all, no lines anywhere.

The crew was friendly and informative. They were very helpful. The

The seats were uncomfortable. They were hard and so narrow I had to sit crooked in the seat to keep from getting banged into by the service carts and every person going by to the bathrooms. I'm not tiny, but I'm not huge either, it was just overcrowded. It was also very hot in the airplane the entire way from Phoenix to Spokane. My husband, who is always cold, was even hot.

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,
