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.

Good crew! Do you call food to a cookie and a coffee? Zero entertainment unless you are carrying your own. At my age is almost next to impossible to be carrying those devices, too heavy!

Walking to the end to find the gate # marked on the ticket, just to find out when I got there that it was the wrong gate, it had been changed. Its hard to hear the announcements in that airport , its a very noisy one. First time in more than 8 years had to pay for 1 suitcase I had

I love WestJet’s in-flight entertainment and the crew was very helpful. There was a maintenance issue that kept us on the tarmac for 2 hours and the crew kept us up to date the whole time.

I ordered a pizza. It was awful. Also, my seat was completely flat - no cushion or support - and I was so uncomfortable.

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)

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.

Arriving and calling someone to help me with the wheelchair was good. The women were so friendly and helpful. But when you're "stuck" in a chair and I arrived early, it would be nice for someone to check to see if you had to go the washroom. And I had to flag someone down to get me to the aircraft. No one came by and offered. But overall fantastic experience. I would fly porter again.

Wish their was more food on the flight. Even though it was a short one.

On the first leg Flight 720: 1. A Black man sitting behind me was challenged (and humiliated) by a Porter agent who came on the plane before leaving the gate, that he was sitting in the wrong seat. It turns out the agent was looking at his boarding pass for the NEXT next connection flight. That delayed the take off by 10 minutes. 2. Then while taxing away from the gate for takeoff, another Black man on the same flight whose mother tongue is not English nor French, did not understand that he had to remove his earbuds for the takeoff. He said he was confused by the instructions, so the the pilot decided he was "non-compliant" and returned the plane to the gate to have him removed from the flight, bring police on the plane. I am sure he lost a lot of money and will have future difficulty flying in North America. That delayed our flight another 40 minutes, and many of us missed our connecting flights in Toronto. I just have two wonder if a white passenger would have been given the benefit of the doubt.

We were delayed 45 minutes without reason, we asked to have our flights switched as we were nervous of missing our connecting flight and were told we could not switch. While we were waiting on the runway for over an hour I asked our flight attendant to check on the status of our connecting flight and she basically told us to hope for the best and that we would have to deal with it when we arrived in Toronto

The pilot was very informative about when we were leaving and what was causing delays

The flight attendant was pretty rude when I asked for help with finding space to put my carry on bag. The seats were INCREDIBLY uncomfortable, they are too shallow and I felt as though I was going to fall off of the seat

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.

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.
