Cons: "no food available to be purchased. we left almost 2 hours later than scheduled and were very hungry."

Pros: "Super helpful gate agents and smooth entry process back into the country."
Cons: "Crew on plane weren’t great. The male attendant wasn’t very understanding when a little girl had to use bathroom before we even left the gate. One of the women attendants ended up letting her go while taxing. Clearly the guy doesn’t understand kids. We could have ended up with a plane smelling like"

Cons: "NA."

Cons: "Flight was delayed 6 hours"

Cons: "Due to the fact that my trip to was not clearly indicated as non stop it is the first time in thirty years of regular travel that I did not have a direct flight to Calgary. Then I was not able to change my flight at the airport even though there was room available on a direct Westjet flight leaving as close to the same time. But the worst part as after landing we waited for a very long time for the plane to pull up to a gate (unnecessarily burning fuel and poluting the environment). And finally we waited another very long time for the doors of the plane to be opened for disembarkation. More than 3/4 of an hour waiting on the ground after a one hour flight very late in the evening. As a result I hat to take a cab home from the airport. Now I will try my best to not fly Westjet."

Pros: "Haven't taken it yet"
Cons: "Well I'm not on the plane yet cause you left.me stuck in Vancouver"

Cons: "Five hour flight delay due to a flight attendant not showing up on time, not taken care of in any way"

Cons: "Woman in seat beside should have taken 2 seats"

Cons: "Cramped seating configuration."

Cons: "To many delays. To Mazatlan and back to Vancouver, than to Winnipeg."

Pros: "I felt like the price was reasonable."

Pros: "I liked the timeliness of boarding."
Cons: "Crew was not the nicest, especially when asking for non purchase items like water."

Cons: "You're confirmation should include a westjet reservation code. That was a nightmare as i could not find a confirmation email through westjet. I needed to go to the airport to find out the day before and they gave me a westjet reservation code. This needs to be done. Other then that, great"

Pros: "Very disciplined and hard-working crew did their best to keep everything under control and moving on schedule. Boarding was busy but fairly well organized considering."
Cons: "Flight had an abundance of minors and babies at no fault of anyone, just unfortunate. Lots of crying, screaming, fidgeting and puking. Customers were pretty impatient in the early morning as well which didn't help the situation. Not sure if snacks or refreshments (other than water) we're handed out in a 4.5 hour flight as well."

Cons: "Not any bodys fault the crew were trying to be supportive. multiple babys all around the area beside accros and a few rows down. maybe set them all to teh back would be better"

Cons: "It was very bumpy ride and scary landing"

Pros: "Crew were all very welcoming and polite"
Cons: "Food and entertainment were pretty pricey."

Pros: "Everything was on time and the staff were friendly! Much better experience than our last trip!"

Cons: "Pre boarding passengers were disturbed by having to get out of their seats to allow other same-row passengers to be seated. If those needing assistance were boarded last all other passengers are settled and could move more easily for them than the other way around."

Pros: "staff was great, left and arrived on time and we stayed up in the air!"

Cons: "Because the flight left late, 3 of us had to RUN through the Toronto airport from one end to the other, in order to barely catch our connecting flight from Toronto to Ottawa."

Cons: "They automatically gave me the window seat"

Pros: "Bell's live TV is probably the best feature!"

Pros: "Although an hour & a half between Nashville to Toronto & Toronto to Ottawa flights. I arrived in Ottawa and my luggage will arrive tomorrow ! Totally unexpectable !!!! Plus only one customer service person to deal with the list luggage of eight people !!!"
Cons: "Lots of other air choices! Bad services WestJet !!!'"

Pros: "online checkin, fast boarding (a total of only 27 passengers undoubtedly made boarding much quicker), had extra space due to the sparse flight; smooth flight, good refreshments, pilot did a good job of keeping us updated on runway/gate status"
Cons: "on board crew didn't seem interested; empty cup was never picked up; upon leaving the aircraft (after a 30 minute delay due to a problem at our gate) none of the crew said as much as goodbye or thanks. I know it was a late flight with very few passengers, many of whom may have slept, but as such I thought the crew should have been more attentive and friendly at departure. A disappointing experience."

Pros: "There was enough leg room and boarding was done reasonably quickly."
Cons: "The flight was delayed by 15 minutes without explanation."

Cons: "The flight itself was great but it was very late in starting due to technical problems with the aircraft."

Pros: "Comfortable"

Cons: "Not enough washrooms for # of people. Denied us of from WR. Food carts blocked WR access to most people for long periods of time."

Pros: "On time."

Pros: "Smooth flight"
Cons: "No entertainment unless purchased. Seats were very tight -no leg room"

Pros: "Comfort and service"
Cons: "Had nit boarded any cognac or gochuchong hot pepper paste."

Pros: "Only thing good was the brevity of the flight."
Cons: "The aircraft was dirty and ridiculously cramped. Air Canada undermines its brand by flying planes like these."

Pros: "The service"
Cons: "Nothing so far, thanks."

Pros: "The purser was most hospitable, gracious, and accommodating."
Cons: "Choices for meals and entertainment were somewhat limited."

Pros: "Everything, we were on time and everything was perfect."

Pros: "Customer service was great"

Pros: "Crew was friendly."
Cons: "My wife and I were seated in different rows."

Pros: "The crew at the gate were courteous and handled my inquiry professionally. Did not experience much because I slept through the whole thing. But the seat was comfortable."
Cons: "Air Canada receptionist (a blonde lady) at Logan took care of luggage poorly while checking in. She was impatient and threw my luggage like it was trash."

Pros: "The movies, and the snacks!"
Cons: "There was 2 passport controls, and the plane was late ; therefore, we had to wait 6 hours for our next flight. Knowing that we had another flight to catch - why couldn't they have held up the one going to Seattle? Originally, it was 5 hours for the next flight, but, that flight was delayed. NEVER will we fly through Canada again. Honestly, we can drive from Vancouver to Seattle in 3.5 hours!"

Pros: "Good food at consistent times"
Cons: "Few entertainment options and definitely blow par compared to other airlines traveling between same destinations Tiny and uncomfortable seats"

Pros: "On time"
Cons: "Not comfortable at all, seats are too crowded, and cabin was way too hot!! Some ppl had to undress their babies..."

Pros: "The flight was perfect. Stress free. I will definitely get it again."

Pros: "The entertainment options were free"
Cons: "The flight was delayed, boarding was a mess. We waited around and took a bus to a small area. Upon boarding the flight attendant slammed a overhead container door on my head, the flight landed late and the bags took an hour to come out. Overall a negative experience for us. We expected this out of westjet."

Pros: "The crew were really friendly and efficient, boarding was fast and easy. (There was a delayed start that wasn't communicated to us) I like that the new audio system the way that it is in front of you so that you can't accidentally unplug your audio or someone else's! There weren't very many interruptions throughout the flight and the staff came quickly when called. Thank you!"
Cons: "The system was easy to use and visually appealing but I found the selection strange; very few movies and many of the same type and the way that episodes of shows are selected, ie half way through a season? The seats were comfortable but a bit small so rubbing against a stranger's arm for 5 hours wasn't the best, but I suppose it was a good deal for economy seats!"

Pros: "Crew was lovely. Boarding flight was easier as we were alou d to go on first with small child"
Cons: "Not a lot of space on flight. The food could be improved."

Pros: "Everything came on time. Staff was professional during a difficult situation"
Cons: "Air Canada seems to lack organization or any coordinated effort through out the organization. They have a fully booked flight and instead of making people with hard case luggage check them they crowd them in on the same flight where there are delays trying to get peoples luggage to fit into the bins. Also through the 4 Air Canada flights flight attends were constantly running down the aisle and hitting customers shoulders and not apologizing. it was also disruptive when people were trying to sleep (these were the 3 flights going to hawaii through calgary and vancouver and then back through vancouver. Probably will not fly with Air Canada again till corporate starts considering clients."

Pros: "Had screens and movies available. Crew was nice and flight wasn't overly packed."

Pros: "1/2 hour late in departing. 2 1/2 hours. Sitting on Tarmac on flight to Toronto. Too crowded on plane"

Cons: "10+ hour international flight and there were no TV's and no free alcohol. There was an option to rent an ipad."

Pros: "All"
Cons: "None"

Pros: "Aircraft was originally booked solid, but a last minute change of aircraft switched us to a larger aircraft so everyone could spread out and get a little more room. Crew was energetic, enthusiastic and pleasant. Overall the flight was above average, mainly due to the friendliness of the crew."
Cons: "Leg room in economy is always an issue (I'm 6'4"). Thankfully this flight was not booked solid and there was no one sitting in that dread middle seat. The food was Mediocre at best. We ordered a pizza for lunch, the toppings apparently shifted in flight and the cheese and pepperoni slid off the crust and was sitting on one side of the box with the crust on the other... (Advice - Stick with sandwiches, crackers and cheese, etc. instead of the hot meals on Air Canada)."

Cons: "We weren't notified via email, text, or phone call that our flight had been delayed almost 2 hours. Found out at the airport. Didn't get into Montreal until 2 am. Plans were wrecked for the night. Flight crew not very friendly."

Pros: "Reliable. Easy to board. On time!"

Pros: "the crew members were friendly"
Cons: "that you don't give any snacks for price of ticket. at least peanuts or pretzels. that's ridiculous. southwest reigns."

Cons: "Change of boarding gate at last minute, no food service in rear of plane due to turbulence however front of plane was served"

Pros: "I liked all the assistant they gave to make a person comfortable."
Cons: "That we had no choice for the seat on the plane"

Cons: "Someone else was sitting in our seats and when asked they said they had lost their boarding pass and hence don't know their seat number. I called the flight attendant for help and he checked our boarding passes and asked us to wait at the back of the plane. He stood there for another 10-15 minutes and we were not helped. Finally, another flight crew member came down to the back and asked us to sit in a row almost to the back with barely any legroom. I am 6'2" and was cramped into the seat. It was horrible!!"

Pros: "Comfort of seats and spaciousness of the plane"
Cons: "Agent off loaded me and only me from return flight with zero reason. Second flight I was put on was delayed 2 hours. Sat for 5 hours in the airport for a 1 hour domestic flight. Customer service was terrible. Emailed Air Canada 4 days ago and have yet to recover any response."

Pros: "SAME AS ABOVE."
Cons: "."

Pros: "Friendly crew Newer airplane (787) On time"

Pros: "Loved the leg room. Flight was on time and got our luggages on time, flight attendants were very nice and helpful! overall flight was very comfortable. will fly with Air Canada in the future again :)"

Pros: "Boarding was pretty quick, efficient, on time"
Cons: "Seats had least legroom of any plane I can remember. I'm not that tall and my knees were in the seat pocket the whole 5 hr flight. Also, the seats could stand to be a lot cushier. I felt like I was sitting on a piece of cardboard after the first 2 hours."

Cons: "My bags were lost and no one would give me contact information for how to track them down. The only number I was give has not had anyone answer after I have called many times over the last several hours"

Pros: "the crew on that flight was very pleasant and helpful"
Cons: "I missed my connection in Montreal because the flight was 2 hours late to get in and Air Canada staff in Lyon had told me I did not need to get my luggage in Montreal but only in Toronto to go through US custom ... which was not true. The airport staff in Montreal was absolutely unhelpful and sent me in 10 different directions. I was finally rebooked for a later flight, and the person there was finally very nice and helpful."

Pros: "Crew Only."
Cons: "AC website states for US and Canada allow 120 mins. We arrived to the airport 130 mins inadvance. We had no checkin bags but we almost missed our flight. (Many people did miss our flight). You need to allow at least 2 -3 hrs for US security checks. Because we almost missed our flight, we didn't have time to purchase food preboarding and the selection in the plane was very limited. My partner is 6'1 and the seat was extremely uncomfortable for him and it was not in our budget to upgrade. There was no free entertainment in the plane. You needed to rent a tableT!"

Cons: "Not serving a meal on a 5 1/2 hour transcontinental flight is unacceptable. Just because you can get away with it doesn't make it good policy."

Pros: "The person we sat next to. And the great flying of the pilots."
Cons: "I am handicapped. Requested a wheel chair from the curb . Upon arrival, no wheel chair. we waited and waited. Then my friend went and got a wheel chair for me. we then joined our two friends, who also had wheelchairs. however, they had first class and was taken immediately to the first class lounge. I was waiting forever behind the check-in desk in Vancouver. I then put my bags on my chair and used the chair like a walker! Still no help. When I asked for help I was told that I was early and I could wait. Not the right answer. I was told to be at the airport 2 1/2 hrs. early which I was. Until I got to the woman at the boarding desk at E84, I was treated terribly. Since we travel with our friends we had hoped to at least see them. No way. Air Canada mad sure of that. also Not a peanut unless we spent money!!!"

Pros: "I liked that the head rests bent so I could rest my head on something"
Cons: "There is not a lot of legroom back in the economy section - I'm 5'7" and I kept hitting my knees on the back of the seat in front of me, so if I was any taller that would have been very uncomfortable."

Pros: "comfortable seats good movies"
Cons: "no food for a 5 hour flight, not even snacks very crowded - not enough room for carry ons the customs procedure took forever, very nerve racking"

Pros: "Flight attendants were very helpful and nice. I saw some passenger asked a sort of unreasonable request (she wanted to switch chicken to beef after she already had several bites), but our flight attendant dealt with her very well."
Cons: "Air Canada: We didn't have a TV screen. We are suggested to use our cell or tablet to use apps. but I only had cell phone. Selection of movie is so poor. I wanted to watch Japanese movies, as I always catch Japanese movie on the way to there, but the selection of movies was mainly kids movie and not targeted to adults."

Pros: "Friendly responsive flight attendants."
Cons: "Dinner not so great."

Pros: "Despite the original delay with the flight boarding staff was efficient at getting us on the plane as quickly as possible."
Cons: "The second part, from Toronto to Houston was the pitts. First of all they called me to the gate way before the boarding time and so I was a bit worried but when i got there there was nothing, they just confirmed I arrived from Montreal. This was strange and so I got a bit stressed as to why they had a called me and made me rush in the first place. Anyway, minor compared to the rest of the experience. The flight boarding was late, then an unscheduled stop in memphis for extra gas, then a tech problem that needed maintenance kept on on the ground. We finally made it to our destination 2 hours late. Most fellow passengers missed connecting flights and because we got out of the airport after midnight needed to get a cab to our accommodations. While I appreciate the attention to safety (and the curteous crew who obviously felt bad and were taking a lot of shit) we what was supposed to be a 3 hour flight ended up being 5 and there were no meals for sale,very limited snacks. We got one complimentary ,half can of juice and a bag of tiny bag spicy trail mix (labelled ranch) that i could not eat. After the delays we got an extra glass of complimentary cranberry juice. Which was amazing, but really did not cut it (from 5:15- midnight). By the end I was uncomfortable and starving! This was a radically disappointing experience in compared to the Ari Canada portion of the trip."

Cons: "The United mobile app as well as my emails stated that the gate was B3. Upon arriving at gate B3 and attempting to board, I was alerted that I was at the incorrect gate. The gate was switched to C11. However, my app did not alert me nore did it reflect the gate change. I didn't receive a text or email update. I had to run to the different concourse nearly missing the fling."

Pros: "Nothing"
Cons: "Lost $700 on this trip. The refund policy was extremely unclear, and the time window for valid trip insurance was extremely short. The purchase of insurance was useless."

The ride was bumpy and the air was again not very strong so we are hot and bouncing around. Finally, we get to San Diego and....they change our baggage claim. United needs to get it together or at least give us a free drink when they can't get organized."
