Crew were good, the food was mediocre when they served lunch - but then there was nothing more to eat until nearly the end of a 9 hour flight, by which time it was past 10.30pm back in London. At that point, all that was offered was half a sandwich and a biscuit.

In-flight entertainment didn't work at first, and then when it started, kept on threatening to shut itself down every time I moved. The selection was ok but nothing compared to other airlines. The screen was tiny and low resolution. The seats were old - the same ones as when BA introduced their premium economy back in 2000. The aircraft was desperately in need of a refresh.

United staff worked with me to book a round-about itinerary on a different airline that got me to my destination within 8 hours of the original flight. Progress announcements were made at regular, predictable intervals.

My flight was cancelled an hour after scheduled takeoff due to mechanical issues. The plane was actually repaired, but the time it took to do so exceeded the flight crew's hours. I understand the practical implications, but in the moment it did feel maddeningly bureaucratic.

Excellent experience with the cabin crew.

Seats on the 777 were too narrow. This 777 had a 3-4-3 seating arraignment, it would have been better with a 3-3-3, similar to a 787 configuration. With the current layout, even with an aisle seat, I was sitting in the aisle. And I am not a large person! The flight was full, so use the 787 and two daily non-stops. For a twelve hour flight, the food was only Okay, could have been better and with a better selection. Meal timing was poor.

Boarding was smooth, aided by being one of the last to board as I was relaxing in the lounge! Boarding was started earlier than listed and complete by the boarding time, long before the flight was due to leave. Crew were polite and courteous, even going to some extra effort to get me a semblance of a meal.

Booked this flight every last minute and didn't order a Vegan option at the time. Was flying business over lunch time so a meal was served. However there was no vegetarian option on the menu. I expected there to be a vegetarian option at least, and I would work around my dietary choice, but with no vegetarian option, this was impossible to do. In the end the crew managed to rustle up something from the Crew meal and I was able to then have snippets of meal segments that suited my requirements. How could this be prevented in the future? Make available a vegetarian choice on all meal served flights. A Meat eater can eat vegetarian at a push but not the other way around. I know if might be too much to ask to make that a Vegan option as standard, because then every one can eat it, but just putting that out there.

Stop trying to be a budget airline and invest in your customers rather than shareholders. Need better seats, free meals on 4+ hour flights, and entertainment. Also, the plane was old and definitely needed interior work (call buttons and lights were constantly flashing and ringing for the last 30 minutes of the flight).

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,
