I like that I made it home alive.

Everything about Departing and arriving was a Poor experience. I might not be using this particular airline again. 4 Airlines now on my list of do not use.

Customer service when my flight was delayed twice and then cancelled.

I hated that there were sudden updates of delays just moments before we were supposed to board, then delayed for a day, then cancelled. I was fortunate to be re-routed to San Francisco (I am on the way) now, through United airlines. All in all, it was a stressful inconvenience.

Nothing good to say about AA

AA screwed up reservations by rescheduling flights by 3 hours earlier (done not once but two times) causing 6 hour layover. This plus an additional 2:38 delay on next flight made the journey horrible. Will never book an AA/BA flight again for intrnational travel.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
