I was traveling by British airways flight BA271 on 13 December 2017. The plane is old but comfortable. I was looking for USB pots I can't find it. Helpful crew and flight comfortable and landing was perfect. British always need to improve. Thanks

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.

From downloading the KLM app to the final touchdown of my final flight, everything was an ease, checking in, the option to change my seat, the service received was great.

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.

Nice seats! Flight tracker. Our flight in the way home was cancelled due to bad weather and although we had to queue for some time all the information we needed about what to do about food, hotels, travel, etc was given to us along with a new flight the next day with seats together. First time I've had a flight cancelled and was impressed with the service I received (now got to try and claim our expenses back so fingers crossed that goes ok).

The curtain that cuts off premium economy getting swooshed across in front of us.

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.

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.

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

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,
