Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Liked nothing. As per previous segment it was delay delay delay.

The staff were the friendliest I have encountered in years. Absolutely great!

Our flight was delayed for almost 2 hours resulting in a rush to connect to our next flight

Good. Would be better if the carry on baggage was free.

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

Limited water service in a 6 hour flight offered at the very beginning and end of the flight.

They delayed flight because lack of staff then missed connection. Never flying with kayak or weather

WestJet claims that tickets purchased through a 3rd party (such as you kayak) they cannot make sure they mention the luggage situation. We purchased tickets that wouldn’t allowed any carry on. WHAT!? So ridiculous. We bought them and there was not one single place mentioning that. Then on our departure the WstJet attendant was a super nasty rude person. Very unprofessional, unpleasant. She should be reprimanded and given some sort of training but I believe that won’t change her nasty disposition. On our return was great, the front desk gentleman was really professional, friendly and helpful. He offered us to pay $18 usd each for our carry on backpacks as they were small (instead of $90 each at the departure, she could have mentioned but decided not to do so. Didn’t print my boarding pass with my full name as in the passport and made the flight delay because the crew needed to correct it).

Scrooge airlines spoiled my last chance at Christmas with my 95 and 92 year old folks. and rest of the family in Calgary. Ticket personnel would not let me on without a passport and I always visit Canada with my enhanced driver;s License when I travel from the US

Flight was delayed due to mechanical issues to the point that I missed my connection and had to wait for 6 hrs in Calgary... thankfully I wasn't in a rush or that would have been annoying

it was great only downfall was that the tvs weren't working but the rest was great specially the wifi

The Entertainment system was nearly useless because videos kept stopping then jumping over segments at random but closely spaced intervals. About 75% of the plane gave up trying to watch and then the gaps and jumps became shorter, It was terrible and made it hard to know what was happening since it was not a normal buffering pause where you still get the cont6en t. Instead the video would pause then jump ahead missing short segments and dialog entirely! The economy class seats on all flights have less and less legroom. I’m tall and the upgraded seats are no better for the leg room, not worth it. I flew from Toronto to Calgary….The staff at YYZ was awesome and kind. My flight’s (prior) incoming plane from Liberia had been delayed over 3 hours and the attendant quickly and kindly transferred me to the earlier flight that got me in hours earlier. Such a great staff!! Every staff member on the plane was very-very Canadian/Kind . Great job and attitude you folks! The plane itself was new and in great condition, except the issue with the video streaming.

I did not like ANYTHING about Discover....see my previous comments regarding our trip. I will do everything possible never to fly with Discover again!!!

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

We were sent via the ac app to a wrong gate. And then got a boarding message to the original gate. Had to run through the airport to get to the gate just in time. Were they purposely trying to trick me? The day before flight was sent a message for free change of flight. Kinda suspect they oversold the flight.

The crew and food were very good. The plane was dirty..

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

Had to buy headphones. Which is sad. I did not so I listened to podcasts and slept. Free beer is excellent a d those pretzels are great too. Overall I feel Air Canada slightly exceeds Westjet for overall experience. But still more can be done. Like allowing guests to view a movie for free.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.
