Nothing - the flight from Chicago to Philadelphia was delayed by about 2 hours. Luckily, was able to get the flight switched to a Chicago - London direct flight.

The connecting flight from Philadelphia to Manchester would've been missed. So, American Airlines booked the same flight for 24 hours later. Luckily, they offered a different flight. Due to the flight changes, the prepaid ground transportation from Manchester to Leeds wasn't used. Transportation from London to Leeds had to be purchased at a much greater additional expense.

They separated my bags, so I had to wait in Philadelphia for my bag to arrive on next flight 2 1/2 hours latter. Not happy after flying from Sydney.

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

I didn't go. It was $400 just to change my name on my ticket from my maiden name to my married name. I am so disappointed and will never use Kayak again!!!

Decent boarding group, same snacks, same flight attendants (who were very nice)

My only gripe is that paying for an assigned seat is only allowed 48 hours before takeoff and costs at least $30, twice what Spirit charges to allow you to select a seat during booking, so it is worse. No one watched us to ensure that we didn’t use the overhead bins (a stipulation of the fare) but we did comply anyway. We chose to take our chances and were assigned seats at the gate 16 rows apart and both in the middle seat.

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.
