From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule.

On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

Fortunately as a passenger the economy flight area was very spacious due to low numbers of passengers. Which provided a comfortable seating space.

The entertainment could and been a little more variable in the film range provided. But generally overall I had a excellent flight. Food was good. Crew were very good and I would definitely consider flying United on my next visit out and recommend that my family did. Thank you United.

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.

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,
