I like WJ but I don’t like traveling anymore

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

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

We were late boarding, but it all worked out. So, no problem.

It was good but not comfortable seat with the long legged persons.

No problems here. WestJet does a good job, even on their short haul flights

Boarding was fine, but then we were delayed a while due to some baggage issues, then de-icing.

Tried to reserves seats and WestJet My Trip shows not available until 24 hours before the flight. When check-in was finally available and I tried to get seats again I was not able to get to select seats for me and my wife together. All in all, was not able to select seats together on Kiwi, paid extra for seats on Westjet and still did not got seats together, not pleasant for such a long flight and with my wife not very good with flying, disappointed on the way the system works with regarding to seats reservations, even with paying extra for them.

Flight full. 'Volunteers' to check hand luggage. Checked hand luggage is lost

Not the fault of WestJet but we had to wait in the plane on the tarmac in Cancun for 1 hour.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

Boarding was unorganized. They expected passengers to ask people to move their assigned seat they paid for in order to sit together. The seats even in comfort are smaller than other airlines and the flight attendants appeared not to be well prepared

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Terrible. 2 hour delay. Sat on the tarmac. Missed my connecting flight. Had to ARGUE with Customer service to get a hotel and food. Terrible experience with my loyal carrier

I liked the exit row seat. Hated the distance between gates in Houston.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Leg room was lacking. Legs crammed into seat in front.

It was delayed several hours which delayed our connection in Denver. Not happy.

I think Air Canada is the only airline I've flown where they don't give you at least a free cookie.

All but one of four were on time. One was delayed for an hour

Not happy with Air Canada . Flight was cancelled got the run around trying to get another flight that was direct none to be found ended up going to Denver then onto Austin adding 7 hours to our trip. Was travelling with some one who had walking issues that’s why we were happy to have a direct flight then it didn’t happen adding more stress on her

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

The wifi I paid for did not work. The seats are tight.

There were no free snacks…little pretzel bag or cookies like we had on our flight out.

Mostly crew good and the flight was safe and comfortable but service was lacking. For an overnight flight of 8hrs 50 it took some two hours to get served a drink and dinner after take off. I asked for Laurent Perrier champagne and was brought Perrier water, which I queried and asked where was the champagne. No response. The issue came up again an hour later when dinner was starting to be served and I was asked whether I wanted another drink, when I reminded I was still waiting for my first champagne! Apologies ensued but dinner service was quite slow. For breakfast I never did get served the hot course! So - no complaints and compliments on the safety of the flight but service underwhelming (and I brought them candies!)

Check in was great! Boarding was very good. The plane was just okay! The crew were great!

On time departure with early arrivals. My last flight arrived 20 minutes ahead of schedule which was great due to my long commute home 3+ hours. The cabin crews on all 3 flights were great. See ya in 7 days Air Canada

Well organized check in and boarding. Aircraft had comfortable seats and lots of leg space, both ground staff and crew members were nice.
