Showed up 3 hours before departure and still missed our flight. The agents were extremely slow and rude. If you have a giant line of people who have missed their flight your system obviously isn’t working. Avoid Heathrow’s British Airways by all means if possible.

Friendly flight attendants and nice to kids

Being held inside the plane for a total of 5:30 hours before taking off. Even if there were several concurring factors, it it necessary to find a better procedure in order to avoid keeping passangers inside a plane with the prospect of taking off in the next half hour repeated every half hour! For the ones of us traveling with children it is even worse, and becomes a real nightmare.

The flights were good. The cancellation was handled poorly.

AA’s flight was canceled from Seattle to JFK. The flight was then rescheduled to Newark and then Orly. The main problem is that the change didn’t include the infant on lap ticket and ended up with 2 hours in Newark trying to rectify the situation.

My first flight with Air Canada (TCA) was 64 years ago in 1953 and the airline still feels safe and solid.

Food seemed OK but we both suffered severe stomach upset after the flight. From gate to gate in Montreal was many thousand steps. Crazy.

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!

The ground crew was very curt and non helpful. Apparently there was a rule that laptops had to be in the checked baggage. The ground crew could have been more courteous with passengers for whom this was a great inconvenience. In my specific case, the person checking me in labelled my bad "Long Stay" instead of "Priority" because they misread the instructions on the computer. The person would not listen to me and would not re-check his potential error....I fly British Airways all the time and that did not seem to make a difference in his demeanor

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.
