Cons: "The crew was overly aggressive with mask policy enforcement. They patrolled the aisles and routine pointed at passengers directing them in a hostile manner to keep their masks on their faces, even when they were trying to eat or drink. They also threatened customers by stating it was a federal law several times. It was very uncomfortable to say the least. I will not fly delta again by choice."

Pros: "Thanks for the monitors."
Cons: "The crew seems tired."
Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."
Pros: "No comments"
Cons: "Cleaners had not done a great job. There were paper napkins left over in the seat pocket from earlier flight."
Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"
Cons: "Late departure"
Pros: "Delta crew is always great."

Pros: "Airbus was nice"
Cons: "Delayed by over 1 1/2 hours"

Pros: "The whole crew was great and very accommodating"
Pros: "Excellent"

Pros: "The crew was wonderful, the flight was on time."

Pros: "Excellent"
Cons: "The seat was very uncomfortable"
Pros: "The crew was very professional, hejpful and had good attitude towards the passengers. This made the flight easy and enjoyable."
Pros: "Smooth flight, on-tome departure"
Cons: "Service in business class left a little more to be desired. I had to ask for food and drinks, because I feel off to sleep in the first round. Came to Gate early, but had to wait for agent to put the jet bridge. Only one person was available."
Pros: "Our flight attendant was excellent. Service with a smile."
Cons: "We almost missed the flight sitting right in front of the gate. No announcements could be heard in the gate area and when we asked, they said they were already removing our luggage, Very odd. Food was terrible! Choices were pasta and cold chicken salad. I had the pasta, which was bland ravioli in two bland sauces. I was surprised, because I had experienced better food on recent international flights."
Pros: "Great service"
Cons: "No complain"
Pros: "Great service all around. As comfortable as you can get for a domestic flight."
Cons: "Food was pretty good, but not up to their usual high standards"
Cons: "Delta staff is not too friendly"

Pros: "Flights were on time boarding was easy. 2nd crew from ATLANTA was friendly."
Cons: "The foldable snack tray was broken on the flight to ATL."
Pros: "This trip into Merida was amazing from start to finish. Something was lost in translation with my handicap assistance in Atlanta, but the trip was lovely nonetheless."
Pros: "The crew was very nice and attentative."
Cons: "The amount of delays causing us to miss our connection and be stuck in another city for a night before getting to our destination the next day(hopefully)."
Cons: "There was a change in our flight. According to Delta you didn't confirm every leg of our flight and the plane was over booked."
Pros: "There was a threat in the airport which caused the closure of one terminal. It happened to be the one from which this flight was due to depart. The crew was calm and able to get everyone on board with a minimum delay, considering the circumstances. The flight crew made up some time in the air and we were able to land less than 30 minutes after our original ETA. Well done, Delta."
Pros: "Smooth and easy."
Cons: "Not applicable"
Pros: "People"
Pros: "Nothing"
Cons: "The staff"
Pros: "I had to take a United flight last week for a short flight and once again I was reminded why I ALWAYS fly Delta if at all possible. United crew hid in the galley the whole trip wit lititle to no interaction with passengers. My flight today on Delta was great; food really excellent (Chicken Tika) and the crew was great as usual. Delta remains the best."
Pros: "Efficient boarding. Friendly service."
Cons: "N/A"
Pros: "The leg room and freedom of not having another seat in front of me throughout this flight was great. It made getting comfortable a lot easier."
Cons: "We couldn't hear the overhead announcements at all. Seated right next to the turbine intake on the wing made the amount of ambient noise especially high, so all the in-flight announcements were pretty much unintelligible."
Pros: "Good seat, easy on and off, everything went a little ahead of schedule and smooth"
Pros: "I was able to pick my own flight online easily."
Cons: "Lack of same day, 1 connection, first class seats. Had to fly out the next day because only middle seats left. Frustrating because I paid for first class and had no good choices for my departure day of choice."
Pros: "The crew were AMAZING and made the flight so much better. Boarding was easy. I also love that the pilot acknowledged the Service men and women on our flight."
Cons: "The older plan didn't have some of the perks that I expected from Comfort +... No conformed headrest, no USB plugs... I paid extra for Comfort + and expected some of these things."
Pros: "Great plane"
Pros: "Staff were courteous. Captain explained reason for delay."
Cons: "Over 20 minute delay to begin boarding with no explanation. Boarding process very slow due to excess carry ones needing to be checked."
Pros: "Upgrading to First Class made it worthwhile."
Cons: "As a minority provider of service at BWI, the gate was the furthest from the entry. Gate security is almost always a source of delay here."
Pros: "After the extremely long wait to check bags which made us miss the flight, the date crew got us in another flight...it wasn't direct which is what I paid for, but they did get us out, but i missed an interview because of the lack of crew and a missing luggage."
Cons: "Checking a bag, delta did not have enough crew to get everyone thru to their flights. We waited for 80 minutes inline to check a bag. Then we ran to the gate inky to find the gate was closed less than 2 minutes before we arrived. At least 20 others also missed the plane because of the lack of crew and long lines checking bags. It was frustrating, irritating, uncaring crew checking in, and a bit rude. Then on of my checked luggage was lost enroute - which made getting off the flights even later which made me miss a meeting that I was scheduled to be at. All because you didn't have the crew needed to check in."
Pros: "...the fact that they got us on the plane and back to GRR even though the connecting flight from BWI was delayed and there was little time to make that last flight out of DTW..."
Pros: "I haven't traveled by air for a number of years, it had gotten to be so crazy at checkin. Well imagine my surprise when I was checked in within five minutes of arriving at the airport. KAYAK took care of everything. All the flights were on time, I received email updates along the way and I am so happy I'm planning my next trip already."
Cons: "Even the babies in the waiting area were quiet on the flight, which leaves nothing for me to complain about at all."

Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.

Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.

The staff was excellent

Blood sucker budgeted airline. Charging after and after. No one should busy air ticket in this airline. Completely a scam and sucking blood.

The cabin crew very kindly arranged a change of seats for us due to a distressed passenger

There was no food or entertainment. That was fine, not a problem. I paid for “priority boarding” ( and a cabin bag) but there was no “priority boarding.” That was disappointing and falsely advertised so perhaps that could be adjusted.

Check in could have went faster and more smoothly

No frills airline. Excellent service. Very good leg room for passengers compared to other "full service" airlines. Crew was very friendly. No entertainment system other than flight information display which was surprising as I thought it would be another revenue stream for them. Overall a surprisingly excellent experience.

Great new carrier to Europe. Lots of leg space and friendly crew

Worst seating -- by several orders of magnitude -- on any aircraft in sixty years of flying regular and budget airlines. The seats are cramped from side to side, barely padded, short from back to front. Tightness was at first absurd and then actually painful for a five-to-six hour flight. Pitch between rows is so small that even turning to stand up to get into the aisle is difficult. And I'm a slender guy, 5'9", 170 lbs. Website for booking held many "mysteries" like hidden access to payment portal. Though one screen said my booking and payment were complete, I learned at the airport that "complete" was not true. Had to work with helpful supervisor at the check-in desk Online I was able to change my flight booking from Saturday to Friday, But also I learned at the airport (too late) that the carry-on bag fee from the Saturday flight did not automatically shift onto the Friday flight. I had to pay the much higher at-the-airport charge, 49 euros. I will try to get an adjustment.

The booking was for the new Icelandic budget airline Play, but Kayak keeps sending check-in information about India's Star Air.

They messed up my checkin which resulted in me missing my connection

Entertainment system did not work

Pros: "Quick boarding"
Pros: "Overnight flight so slept. Flight attendants were friendly and helpful."
Cons: "Cramped seating. No entertainment."
Cons: "Air Canada needs to step up their game and get better in seat technology."
Cons: "70min delayed departure exhausted a three hour window I had to get through customs, get my luggage, and get on the London Underground to get to Liverpool Street Station for my connecting train. Means I’m out $40 Canadian for a ticket that went unused."
Pros: "We arrived safely"
Pros: "Friendly, helpful crew."
Cons: "Awful headphones"
Pros: "everything"
Cons: "no entertainment"
Pros: "Price"
Cons: "Power outlet's didn't work"
Pros: "-Great food -Great room -Great people"
Cons: "-Movies were the same; not much to pick from"
Pros: "Great service, multiple meal/snack services and staff was friendly and helpful when needed,"
Cons: "The customer service line through telephone was not very helpful and seemed to cause more worry when we ran into a problem with our flight."
Pros: "on time"
Cons: "Passengers checking luggage are better off waiting in the economy line - it moved much faster than the business class line."
Pros: "This was not a Luftansa flight!! It was Air Canada Rouge which is a budget airline that doesnt compare to Luftansa"
Cons: "The fact that it said thia was a luftansa flight when in fact it qas not"
Pros: "Seats are very uncomfortable. Air Canada used to be one of the best airlines in North America now I would rate them as one of the worst! Every since they started the air Canada rouge flights. Most uncomfortable seats in the business. Also staff from call center to check in are rude and act like they are doing you a favor."
Cons: "Direct flight"
Cons: "2 hour delay, lack of connecting ticket made me have to go through security all over again, the "entertainment" is an app for your smartphone/tablet."
Cons: "Flight cancelled until the next day and then delayed again without sufficient notice . Air canada hasn't offered us anything worth making up missing a day out of our vacation"
Pros: "Crew on board as accommodating as they could be."
Cons: "Arrived at the airport to find hundreds of people on line trying to check in. No Air Canada employees were explaining anything to anyone, as we all stood in line for over a hour, nervous we'd miss our flights. Word was passed from the front of the line that the system was down. They held planes, so I guess everyone eventually made it to their flights--but not until everyone was stressed out to the limit. Lack of assistance from Air Canada personnel was glaring."
Cons: "Going through 6 stages of security!!!! I understand to be safe, but good grief! I bought a bottle of liquor in the duty free at the Budapest airport thinking doing it this way I would not get harassed. Wrong!!! They freaked out and held us up even longer! We almost missed our last flight because of all the security steps we had to go through!!! And so did many other people. It's a ridiculous system, it should all be done at once with only having to stay in the long line ONCE! And to scan our own passports and waiting to see our name on some board to be able to leave that particular room just to be met with even longer lines afterwards is insane. I am not a tech savvy person, as I am sure a lot of others are not either, and I got barely any help to show me how the heck to do all of that! Unacceptable!! And to top everything off, an item was stolen out of my daughter's suitcase somewhere along the way!! Replacing it cost me about $40!!!"
Pros: "Once I made my flight (the next day) everything went smoothly"
Cons: "Online checkin does not inform passenger if their passport is suitable for travel. Although my online checkin was successful, once at the airport the attendant would not allow boarding because expiration was within 6 months of travel - a requirement for certain countries. It would be much more efficient - for airline and passengers - if the online check in system can catch this before arrival at the airport."
Pros: "Nothing stood out as being too great. I was too pissed off from the delay to really notice any good."
Cons: "We were delayed about 2.5 hours. Ridiculous."
Pros: "That we arrived, finally, safely and our bags did too."
Cons: "The kiosk at checking was unable to process our boarding pass so we had to wait in line to see an agent to check in and take our bags. There were 3 lines, but people who arrived after us were taken care of before us. It was not organized. Our flight was delayed and the waiting area at Laguardia was so crowded. I fly Air Canada as seldom as possible because there's almost always something that complicates the trip. Our daughter booked these flights so we could visit her for Mothers Day."
Pros: "The food was pretty good!"
Cons: "*The in-flight entertainement required you tonise your own mobile devices, but locks "premium" content (movies) and forces you to install an app to view it - which you can't do once your on the plane and have no wifi. Also, there's no way my iPad would've lasted 7h without a charging port anyways..."
Pros: "The plane was comfortable, the boarding easy, the flight pleasant, good views."
Cons: "Plane employees did not explain what the declaration card was meant to serve. I left mine on the plane by mistake, partly due to complete ignorance of its purpose. Please either put the purpose on the card or have your flight staff explain what passengers will need the card for, once they get to the next inspection point. Don 't take this for granted!! The long walk from the point of deplaning to the center of Pearson Airport was unexpected."
Pros: "Everything was perfect"
Pros: "I liked the service crew and flight attendants help. It was amazing to come home safe. I enjoyed my flight."
Cons: "Nothing at all."
Pros: "Nice. Great way to return home and have wheels damaged on one piece and handle cracked on another one."
Cons: "and unexpected change of flights led to cancellation of flighs. Never ever Air Canada or related airlines"
Pros: "All was well. Thanks"
Pros: "The flight was on time, boarding was well-organized, the service was friendly and helpful."
Cons: "The line to the washroom was quite long - there were only two washrooms at the back of the plane."
Pros: "The service was fantastic flying over night is never fun but the staff made the plane very comfortable"
Cons: "The plane was very cold"
Pros: "Aircraft had TV screens for each passengers offering a variety of free entertainment for all passengers. (Nice)."
Cons: "i am a 6'4* person and flying on any "express" aircraft is a mild form of torture. I know this is not exclusive to Air Canada but come on North America...lets get that leg room increased. ; )"
Pros: "No in seat entertainment console. You had to use your own device or rent one. No recent movies, just older ones."
Cons: "Small legroom and poor selection in the entertainment provided via wifi"
Pros: "The crew was excellent. Professional and attentive."
Cons: "The only real complaint I had was the over head compartment was much too high and I was too short to reach."
Pros: "Easy flight , no late"
Pros: "The pale was nicer than my flight out. The food was very good vegetarian fare."
Cons: "The seats are just too narrow! My shoulders were practically grinding into the person's next to me."
Pros: "Short flight"
Cons: "Felt like spam in a can."
Pros: "Got to spend the night in Toronto unexpectedly."
Cons: "Due to Air Canada's I missed my flight to Amsterdam. I missed out on a day of sightseeing and having fun and Amsterdam instead I spent a day in Toronto. I was able to get on a flight 24 hours later. This missing connection happens routinely with Air Canada, for some reason they have not managed to fix the error."
Cons: "The food was horrible"
Cons: "Flight delayed half hour, rush through all the steps, we are the first one get to the plane. But all the other people can not make it because we sit at near front and started the rush earlier. However, all of our checked luggage so can not make it. We are waiting for delivery on the next day. This type of short connection of international flight should not be arranged as we told you and AC when you told us the original booking was changed due to AC flight modification."
Cons: "Flight was delayed for over 4 hours due to Air Canada fault, no crew at the gate to provide updates, forced to gate check all carryons, missed connection AND rebooked connection. Canada was lovely, too bad I can't say the same about Air Canada."
Cons: "Uncomfortable airplane. Old."
Pros: "Fast"
Pros: "Everyone was very friendly. I liked the spaciousness of the seats. I did not feel like I was sitting on the person beside me we were both comfortable"
Cons: "Constant back and forth of the carts. The smell of the food while the cart is parked beside you is rough to if you are not feeling well. Felt like too much selling going on. I don't' need to be asked so many times about food and drink."
Cons: "Food"
Cons: "We were delayed because the plane was late from Toronto, and were told this when we all began to check in up front. When the staff finally did come to the desk at the gate, they still maintained (and rather rudely to some of the other passengers) that the plane would be there by 7-- turns out the plane got there about 7:30, rebooking flights that were going to be missed was like pulling teeth for some of the passengers, and we took off about 8 (1 hr 40 mins late)."
Pros: "Great service on a quick flight"
Pros: "My first flight on Air Canada ever. It was a short flight from Newark to Toronto. The flight was full and there wasn't enough room for all passengers' carry ons fit. The cabin crew worked cortiously, diligently and expeditiously to check those carry ones that could not fit."
