Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Delay and keep changing gates. I have to run around from B to C then to E.

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.

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.

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.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

We didn’t make the flight due to Delta’s check in line moving too slow.

The flight was ahead of schedule. A half glass of juice and a cookie is pathetic! No entertainment possibilities. Not even a plug-in for phone or IPad if you wanted to watch a downloaded movie. Back to flying Air Canada!

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

Plane changed to one with no entertainment system or ability to serve hot meals

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

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

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

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.

Plane should have entertainment, instead of people paying to use wifi

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

Very nice comfortable spacy Airbus 321. I liked the offer of food on the Bistro menu. The idea is very good to pay and cost was low.

Great overall. Quick boarding, attentive staff - great experience in premium class.

When arriving over 2 hours early to check k in at Charlotte airport I was told I would have to check my carry on ? Apparently the flight was full and may not be room. I was not given a choice and the agent was quite unpleasant about it. I am a senior amd was not comfortable me having to worry about my bag being lost vut it didn’t seem to bother him. There were lots and lots of people of all ages in line when we boarded with carryons and most larger than mine .the rest of my journey was pleasant vut this was totally unacceptable.

The layover was 6 PLUS hours and we were only given a $15.00 voucher. We missed our first activity in Quebec due to the delay.

Miserable staff as it was a late/delayed flight and crew wasn’t in the best spirits. Completely understood as neither was most of the passengers. Still unacceptable l.

It was a short flight, and no entertainment. That was not a problem for us, but there is no option for "not applicable". There was a bit of turbulence, so there was no food service.
