I feel like the overall product is so devalued at BA these days. It just doesn't feel classy anymore. As opposed to Lufthansa, which is an example of a European carrier that cares about passenger comfort and experience. Also the typical circling of LHR to get a slot is annoying and makes me want to avoid BA.

I bought 2 tikets from Chicago to oscow and back for me and for my son. I live in USA, son lived in Russia but he received immigration visa and I had plan fly to USA with him. From Chicago I used my ticket and say SWISS staff what my son will have trip only from Moscow. I paid for 2 tickets around $1700. Today when we should have trip back to USA, SWISS company said what ticket for my son do not exsist. And I spent for new ticket 220000 rubles about $3600. Nobody in SWISS company do not said me what my tocket for son canceled. I am shoked !!!

Then she realized that her comment might sound racist (so she apologized), then she told me that I could not put my small bag under the chair.

between lunch and supper snack one isle had only one water serving and my isle had none. So for 6 hours we had no water serving. This is why I gave crew rating OK only. Also the supper pizza snack was horrible. By comparison, United gives full drink cans so they last longer. I suggest Lufthansa also should serve full drink cans in long flights.

They knew my flight left at 9pm, still gave me ONLY 1 hotel voucher so I was kicked out of the hotel at 12pm with NOWHERE to go for NINE HOURS with 125lbs of luggage. 4. They provided a good voucher, but the cheap hotel they put me in didn't have a kitchen, USELESS. 5. The flight was LATE getting to London the next day and I missed my BRITISH Airway connecting flight to Thailand. Had to wait another 7 HOURS to get a flight out. 6. Terrible service, over priced and rude agents. The agent told me " I don't know who waived your fee yesterday, but I'm not." Cold, considering the plane I was on the day before was shooting fire about to explode. 7. I was rebooked no choice of seating or consideration.

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.
