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"

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

Airport monitors did not give the gate for our flight returning Detroit to Vancouver Juice served from glass storage containers are a far more healthy alternative for people. And would also minimize the need for recycling plastic or aluminum containers

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.

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

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

Our recent flight from edmontown to kahalui was excellent. The service staff was very friendly, knowledgeable, funny and attentive. Thanks to all involved that made or travel such a pleasant experience and we hope to fly with west jet again soon

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

No real issues just wasnt able to hear / understand any announcements flight attendant was making but everything else was really good- ended up checking my carry on case for free which made deboarding quicker. I would fly West Jet for all my flights.

Seats were comfortable and leg room was good. Slight delay for boarding but nothing too bad. Would fly with them again.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

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.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

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

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

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

There was no food on this flight. We had less than 1/3 full plane and were not allowed to spread out. Staff gave the story of the plane had to have all of us up front for 'balance.' Total bs.

There were changes to my flight with many email and very difficult to keep up with details of changes. I consulted Air Canada website that said I was to depart Casablanca at 9:35 but when I got to airport that take off time was delayed by 2 hours. That's 2 hours at an airport instead of bed. I don't understand why Air Canada website didn't show the change in take off like they showed the change in transfer. Do better.

Cabin staff could have been more attentive & appear to enjoy their job. Were fairly disengaged.

I was delayed from Montreal to Tokyo for 3 hours and they didn't compensate anything
