Great flight, comfort, and staff. Prefer tv in back of seat but watching on phone will do

10.0 ExcellentDarren, May 2023YYZ - LAX
Read more about WestJet Encore reviews

Great flight, comfort, and staff. Prefer tv in back of seat but watching on phone will do

Pros: "Friendly staff and the support they offered to my mother who needed a wheelchair."
Cons: "I would have liked to have had WestJet internet and entertainment access. It was not offered on our flight from Toronto to Fredericton."
Pros: "The fact that military personnel and retired military personnel and their spouse can check in luggage for free. The check in crew was also very courteous."
Pros: "It ran on time. The pilot landed the plane without a big jolt. We could board and deplane using 2 exits."
Cons: "Seat space"
Pros: "Rotten stuff cancels out the good doesn't it. Be great if you could take some courses from Stephen Covey as you are missing some skills sets in hospitality. And stop being so cheap with the 3rd rate old old movies!"
Cons: "I did not appreciate having the second row to the last on my 2nd plane coming back - I only had a turn around time of 20 minutes to catch my third Westjet flight. When we asked if the plane would wait for us - your crew just laughed in our faces."
Pros: "Great, friendly crew in this scenic trip across to Victoria. Nice new aircraft operating this route."
Pros: "Cheerfulness of WestJet employees."
Cons: "Seat comfort; seats hard. Person next to me average size but still spilled into my seat with “man-spreading” and shoulders."
Pros: "Efficient crew and reasonable seating"
Cons: "Need more legroom or a device to fold passenger legs for the flight duration..."
Pros: "Crew was good. Seats need to be updated and are confining. I appreciated being able to disembark through front and rear door."
Cons: "More space between the seats."
Pros: "the crew was very polite but the flight was too short to have a meal"
Cons: "delayed embarking"

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

Horrible experience from start to end. Copa costumer service is non existent. They treat you bad. Everybody tells you different information. We didn’t received our luggage in the 1 day stop we did even we they said if was not going to be a problem. They didn’t respect the seats that we had and spread our family leaving in between of two big people who didn’t leave any space for me and crush me from side to side. I’ll never recommend Copa to anybody.

I liked the friendliness of the crew and comfortable flight. All good.

Cons: "The turbulence was really bad ! I couldn’t sleep at all !"
Pros: "No drink because didn’t open de bottle. No one care about it."
Cons: "The amount of turbulence experienced was ridiculous. The landing was rough. This was the same for every flight with Copa on my round trip from SJO to MDE. This was extremely concerning."
Pros: "Profesional, on time and quality service. A tremendous difference to the US Carriers. A+ based on price, service and amenities"
Pros: "good crew, food was okay."
Cons: "really uncomfortable seats, too small for an international flight. couldn't lean back because the guy behind me was tall, so my back was hurting the entire time."
Pros: "Food was good"
Cons: "Different movie, more leg room but I'm tall so that is with any plane."
Cons: "Zero entertainment which seems like should be standard these days"

Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Boarding was a little chaotic but it was a very large flight. It just wasn’t fast. And there was no noticeable difference between zones boarding.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore

Air Canada continues to disappoint in almost every way. Probably the result of a monopoly, so NO need to improve anything

My flight has been canceled and I had to cancel entire trip.

Air hostess delayed providing food and then pulled away the tray before i finished eating

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

Entertainment catalog certainly needs an upgrade to include better and latest content. Food was not good at all - they need to cook something edible. Five starts to the crew and on tim performance of British airways though!!

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Crew and boarding fine. Flight delayed, then delayed again after boarding.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

Great and pleasant service and smooth flight with wonderful and clean amenities.

American was good / British Airways partner was not as good…
