food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

The staff on the WestJet flight were friendly and helpful. The flight was smooth and we arrived 30 minutes ahead of time.

not as spartan as an air Canada flight, less comfortable / no in-flight screen as compared to similar priced Air Transat flight. Crew Cabin were professional and approachable. They got the job done, safe flight, on time despite delay in take off.

There was no entertainment and no announcement till well after I and others asked about it, and no "compensation" (like a free snack)

4 hour delay, lost our bags, staff was loud and it was an overnight flight

Entertainment was the only issue. I did not have app & not equipped to watch movie on my phone. Used to other carriers with access to a screen for viewing. Other than that, everything was fine.

Great flight. Pilot was able to fully make up the 42 minute late arrival of the aircraft for an on time arrival in Toronto.

Westjet delayed then rebooked us on flights for economy class when we paid for business class and now need a refund for fare difference and they aren't getting back to us

Our plane entertainment system was out… That made for a very long flight. In my opinion, WestJet should consider a credit or a partial refund for that.

I liked when we actually were allowed to get on the airplane back to Edmonton… What could’ve been better well, not having our flight be delayed five hours could’ve been better… And then canceling our flight from Edmonton to Toronto, and then rescheduling us to fly from Honolulu to Edmonton -Edmonton to Vancouver, and then Vancouver to Toronto with a 12 hour layover in Edmonton pretty much was hell… Total travel time to get home 38 hours that’s really what could’ve been better. The two gate attendants for WestJet in Honolulu told us to come back to the gate to try to make other arrangements because they had to board the Calgary flight 1st and they didn’t have time to talk to me but by the time I came back when they told us to they said you should’ve come earlier to make these arrangements everyone else already changed their flights… We found out later that 30 people did not get on the 2:30 AM Edmonton flight. They ended up getting on the midnight flight to Calgary and making other arrangements to Toronto and so forth which we could’ve taken advantage of that if they had allowed us to when I initially had went up and approached the two gate attendance one of their names was Denise. One of the kindest WestJet employee was the one who received us in Edmonton, who felt so bad about the entire situation she got us for more meal vouchers and flew us first class from Vancouver to Toronto. In Honolulu they had given us two vouchers to use for dinner and they weren’t valid outside of Canada so we had purchased a meal and they were completely useless… But nowhere did it say that they could only be used in Canada So when we received more food vouchers in Edmonton, all of them did end up working in Canada, but it was just so convoluted. Overall, we have traveled to other countries even going as far as Africa… and that experience was far easier than flying to Hawaii from Canada I cannot believe any of this happened and how inconvenient it was We arrived, exhausted after 38 hours of travel, and could not even go to work on Monday. I look forward to hearing from KAYAK or from WestJet for some sort of compensation over the situation.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

The male air hostess was rude and didn’t even offer me a drink. Poor customer service!

We left really late. Things that were out if anybody’s control I guess.

The weather caused a delayed but I was impressed how United did everything they could to try to get us out which included bussing us to the plane doing a Hardstand and bringing us to the plane since the fog was too thick to tow the plane from the overnight stay in the cargo area.

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.
