Good Movie Selection, food was descent, no screaming children,

Layover in Frankfurt too long; Unable to sleep on flight, nearby windows were open creating too much light, seating a bit too close to relax.

We did get to our destination.

Flight was late, as always. I couldn’t sit with my spouse. Rows are so tight, one can barely get in/out and we are smaller than normal size. Baggage fees make overhead compartment loading a real nightmare. I wonder what they will think of next to make flying an even more terrible experience.

Boarding was seamless and straightforward

Crew - Mostly men that looked like they hated their jobs. They were mostly unfriendly, and getting any of them to crack a smile was like pulling teeth.

My husband and I paid a combined $100 to reserve seats on our flight from LAX to London. When we got to check-in at LAX airport we did not get our reserved seats. Everything had been changed around. We did not even have seats next to each other. Upon complaining at arrival in London (there was no time at LAX to deal with this, as usual that airport was one chaotic mess) we were given a British Airways business card with a phone number that did not work/had been disconnected. I would like to get the $100 reservation fee back. Thank you.

no mention of visa entry to US when I booked my trip !! caused me all sorts of problems .... you must make double and triple check that when booking a ticket to a country that requires a visa it is a 'click to accept' thanks

The flight attendants were very nice & accommodating. Everyone made you feel welcomed and valued. The food was fresh and you could tell there was a lot of detail put into the trays, they were well presented.

No complaints, it was really a great experience.

The movie and television options were fairly good.

I usually enjoy the BA flight from London to Austin, but this flight was extremely uncomfortable. The seats were cramped, and when the woman in front of me leaned her seat back, I didn't have enough space on my tray table to even keep a laptop fully open. The food (chicken casserole) was also terrible, and the airline ran out of other lunch options by the time they got to the back row where I was seated.

The drinks were great, however the food specifically the salmon meal (Great Britain breakfast) seemed to be missing something. The stewardess mentioned my partner to have the chicken as there was only a portion of the meal. But, I paid £24 for the meal. Although, the vegan and veggie meals were great!

Next time I will pay more attention to the two row seating and pay for seats in that area of the plane. Other than that, good service.

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.
