Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

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

Boarding, staff and flight great. A bit disappointed with no in flight online entertainment but I'll live. Landing was a bit of a jolt (more than usual) but hey everything else was smooth. LoL

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

All as expected. Flight on time and journey was uneventful

The on time performance and the ease of boarding are great. The crew were cordial. During landing the pilot made a hard landing with some swerve that was a bit rough but other than that everything else is as smooth as it can be.

1.5 hours late departing YVR for a 14-minute flight. Packed waiting area. Full plane. Families with tired, screaming kids. 40-minute wait for baggage at YYJ. For a Dash-8. Obviously there was some kind of breakdown but there was no communication from anyone. Most of this was not WestJet's fault but it was an unpleasant night overall. I fell asleep in a chair waiting for the luggage carousel to start.

Nothing to like about flying in the Dash 8s. With very small seats, little legroom, and a very noisy plane, nothing about such trips is enjoyable.

Horrible, flight on the way to Vegas was delayed significantly and then on my way back my second flight was cancelled

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

I couldn't rate food or entertainment as neither were a factor in my short flight. I was impressed with with respect of time and schedule. Also, this was an incredibly smooth flight from terminal to terminal. My only minor complaint was being woken up for refreshment service. This was the end of a very long day, and I was happy to miss a juice box and pretzels for a little rest.

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.

Not full, so lots of room, which is really the only thing that can make flying economy more comfortable. Direct to Toronto is great! I didn't eat or use the entertainment.

It was overall above average experience. If there is only one thing i could complain about was the lack of wifi availability on my flight from Vancouver to San Francisco

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.

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!

I think all and all they are doing a good job. Flight crew worked hard and very helpful,polite and attentive

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Overall great flight experience- on time, lots of food and movies.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

bad seats, meager food quantity. bread not fresh. Hollywood films lack entertainment.

Great flight. Left on time, not very crowded. Quiet and the right temperature.
