Customs was disorganized and we were sent to the back of the line twice. The people working there didn't know what they were doing. Then our flight was delayed 3 separate times, first 2 hours, then another hour, then another hour. The seats on the plane were made for children. Luckily it was only a 1 1/2 hour flight.

this flight was cancelled after we boarded and no other flights were available until two days later - completely unacceptable for a 1-hour flight for which most people travel for a weekend, particularly when other airlines sent flights safely in the same conditions (Air Canada later that night, Porter early the next morning)

My first trip started on a poor note; I got to airport about an hour before boarding, only to find out that my flight was rescheduled from 9:30am to about 6:15pm ( or so) on that same day without prior notice. I went up to the counter and asked for confirmation for the switch and inquire if there was an issue, which may have affected my original flight. Turned out that the change was due to weather conditions at Toronto (makes sense). I had suggested that it would have been nice to receive some sort of notification, before starting that day way too early and inconvenience of going to pickup my car from the airport parking, only to come back again. The attendant sympathized with my plight and compensated me with a lunch voucher (which was nice of him and WestJet). Matter was resolved; I came back to catch my flight and the trip was wonderful :)

I didn't like the fact that my flight was rescheduled without receiving any notification from Westjet.

Re-booked on Westjet after my WOW airlines was cancelled. Didn't know what to expect - pleasantly surprised, Great service from top to bottom leaving Gatwick Airport. Will make them my top preference in searching future flights out that way.

Nothing - the entire experience (check-in, flight, deplaning) exceeded my expectations.

The Wet jet staff were very accommodating and lovely. The on board staff and on ground staff did their best to be very accommodating during very problematic weather issues related to Toronto.

We were given wheels up time twice due to delays in Toronto for freezing rain. I ended up changing my flight to a direct from Calgary to London. The amount of time spent in the airport was definitely a negative.

Flight was late leaving toronto, missed connection to knoxville. Captain/crew never gave explanation. United just kept saying the captain needed more time before boarding. Got to Washington and had to wait 5minutes before the tram left for gate A. United should have known we had arrived and were on our way. I paid a premium to get home at 2:15. I could have paid a lot less to get home over 4 hours later. !$10 food voucher didn't make up for that. Also, we didn't even receive an apology!

The cabin crew provided the most information out of the entire experience and were extremely friendly. I appreciate Dawn in particular. The lounge is nice when it is not so over-crowded. I appreciate some complimentary minor snacks and drinks; it certainly helped with the delay. What would normally be sufficient seating and power outlets became people tripping over each other with delayed flights.

The lounge staff were hard to find and not communicative about delays. The board only had 1 update to my departure time, which was 30 mins after the originally scheduled time, and did not update again until 25 minutes after that second time had passed. The lounge staff did not make an announcement until after that board update and even then the information was wrong. The one time I found someone to ask a question to, I was given the same information. I had no idea why there was a delay or what to expect and no way of finding out. It made coordinating next steps upon my arrival to my destination extremely difficult. The lounge is not particularly well-equipped for multiple delayed flights.

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.

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.
