1. Plane engine set fire while taking off... leaking fuel. 2. My bag fee was waived, but the next day after being grounded and put in a cheap hotel for the night, I was RECHARGED $100. 3. 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.

Late BA flight made sure I had to wait 7 hours to catch and EVA air flight. I want my money back. I paid 1000 to flight British Airways not to be crammed on a flight as a show away. Super uncomfortable seat on EVA and a terrible experience. I fell on the plane.

I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

Took two hours to start dinner service without a reason. Turbulences and a passenger with long legs were impeading my sleep but not Lufthansa's fault.

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.

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.

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.
