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.

We were unfortunately stuck on the tarmac for 45 minutes. I ran to my connecting gate but they had already closed it. There wasn’t a service rep at the gate. I walked to another gate and there was a very helpful rep who rebooked me to a nearby city. It overall was disappointing and caused me to get home about 3 1/2 hours later.

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,
