I was rerouted during my flight Houston-Manchester, my bags are lost that had Christmas presents for my children. British airways have compleatly let me down I have no means to replace all the items BA have lost . May I suggest you take a look at what is going on with your baggage handlers ! The Flight attendants were Miserable it was clear they didn't want to be there, One of the Flight attendants was sat in the kitchen looking like she was about to cry.

Pleasant staff

My husband and I chose seats together when the tickets were purchased and when we received or boarding passes they had been changed, separating us. My 6 foot 200 lb husband ended up against the window in a row with 2 women that were both well over 250 lbs and I was seated with strangers. No free movie as there was on the trip to Texas

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.

Ok, I get that I checked in on the first half of the round-trip too late to get a cheaper rate for checked baggage, why I charged the increased amount for return flight made no sense. Also it would have been nice to know that you needed to check in more than 24 hours in advance to avoid the baggage surcharge. No party to this transaction bothered to tell you.

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.

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.
