I am extremely disappointed in how the repeated delays were communicated with waiting customers. It seemed dishonest. We were delayed by over four hours, but in a way that kept us all sitting near the gate, not knowing what would happen. People were visibly upset, hungry, uncomfortable.

I flew business class for this trip and loved the leg room!! Having frequently flown coach class on these overseas flights, I have a hard time folding my long legs into the cramped seats and arriving rested and in good humor. I can say unequivocally that the flight attendants give you much more personalized attention in business class. I didn't have to, but I preordered my meals and that info was registered, and that way I got what I wanted. I also made use of the Admirals Clubs during layovers.

Booked flight through British air for a reason. Didn’t anticipate American Airlines being used for our flights. The Flight was also delayed but it was never explained why despite dozens of questions from passengers. This caused a missed connection flight and forced us to stay overnight in Chicago with nothing but a $12 food voucher. When we tried t ask what other options were, American Airlines personal offered no sympathy and said the best we would get is the food vouchers and we should be grateful. No other travel reimbursement or vouchers were offered other than a replacement flight. Overall it was a huge inconvenience and caused numerous other expenditures for us.

From the original price of tickets, to the rude and incompetent phone service used when purchasing seats and bags (because the website didn’t recognize my reservation) to the excessive cost for bag checking and carryon charges, I’m going to have to say: this airline is terrible. The flight attendants are rude, and the plane has limited leg room (which by the way you can purchase extra for additional fees). Ridiculous. Save the hassle and fly Southwest.

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.

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.
