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.

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.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

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

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Departure delay on a late night flight. Made us even later. Tired but got home.

Westjet forced me to put my carry-on baggage in check-in probably because I was assigned seat 23A (the last row seat), which had no cabin space, which is unfair. I wanted to carry on my luggage so that I don't have to wait at the airport for my luggage. Also, because there was no cabin space, I was forced to keep my laptop bag under the seat, which I didn't want to as I was carrying 2 laptops and charger. The airline should basically tell people that if you are assigned a last row seat, then you are not allowed a cabin baggage or a personal item.

Easy processing, flight time was quick and staff was professional and kind.

The flight was delayed and I missed boarding my 7 day cruise. I had to book a separate flight home

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .

The crews are great.. Easy boarding. Inflight entertainment ok. Food is a disappointment.

The real big issue with this flight was that it was 3 hours delayed. Other than that, no big praises or complaints.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Well you cancelled our direct flight to Austin from Toronto granted you got us on another flight but sent us to Denver then onto Austin delaying our arrival time in Austin by 7 hrs I was flying with 3 other people none of us were happy with our Air Canada experience

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.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

First My Flight was Delayed for Over 3HRS, I missed My Older Sister's Funeral, My Car Rentals I Missed it, Had to take Uber from the Airport and then to Rentals Next Day

As usual with Air Canada, being on schedule would be nice. Tv kept shutting off and having to reset it by staff every time. Irritating.

Air Canada was great and boarding was fine. The issue was that we received an email from Air Canada to check in (we were directed to Air Canada’s website). When we tried to check in online we couldn’t. So we decided to go to Air Canada check-in desks at the airport. When we arrived there they said that we needed to check in with United Airlines (which was in a different terminal and required an air train or long walk to get there). There was no indication during the booking process that we needed to check in with United so it was impossible to know. Hopefully this can be fixed going forward to travelers know which airline is processing their check-in. Seems like a basic thing that should be communicated during the check-in process. Other than that, everything else went well.

Both flights were good however , zero entertainment on YYZ to RSW flight. Helps to have some distraction on flights over 2 hours.

Their 737s are not equipped with WiFi in this age.
