Pros: "jFk To DCA crew is fine and helpful."
Cons: "Crew and flight from DCA to JFK was terrible. We left over 30 minutes later with no explanation as to what was taking so long. There was no info given to passengers in regards to what gate or terminal you’re landing and in- was only given 20min to get to gate c Terminal 2 from gate b terminal 4.0"

Cons: "No food"

Pros: "Excellent service, God flight"

Pros: "Customer services"

Pros: "I board sky priority or sooner so it always goes well."
Cons: "Delta could do a little more to align people behind the right zone pillars when lining up for boarding. Passengers especially those not used to flying or flying with Delta are always confused. Maybe some stripping on the floor could help or pillars at the front and midway back."

Pros: "Delta fo"

Pros: "NONE"
Cons: "The service was terrible. Also a ripped off base on I was expecting to be treated as if I was on Virgin nothing compares to it . Delta plane making a loud noise we can even heard anything when pilot does announcement. I want my money back or I should be reinbuise some how."

Cons: "Nothing"

Pros: "Good experience overall. Pleasant staff. Movie features were wonderful and helped pass the time."

Pros: "The service. The plane (seemed like an international plane). Food options. The service and the service. There was a problem getting on, they allowed premium members to board but when I got to the plane, I was scolded by the cleaning crew lady (maybe the Mgr) that they were not ready and that she had informed 'them' of that and that no one is allowed to board while they are cleaning."

Pros: "Free food for all on this flight! Turkey sandwich was actually quite good! Great legroom, flight attendants, and pilot. Free great movie for all."

Pros: "Great staff!"
Cons: "Nothing"

Pros: "Everything"
Cons: "Nothing"

Cons: "Entertainment options are old. Food in unaccomodating for Vegetarians."

Pros: "Many airlines have code share flights but it is better to buy ticket directly from the original airline as they keep on ignoring the code share flight bookings"
Cons: "Till last moment we were kept hanging if we will board or not as no seat number was allocated. I believe it was as we were from the code share airline not the real one"

Pros: "Love it"
Cons: "Nothing to report."

Cons: "The crew was very friendly and efficient and the flight boarded, departed, and arrived on time."

Pros: "Everything was great. The food was tasty and the flight was comfortable."

Pros: "Chairs and the space was very good."
Cons: "Crew and the food was very poor. This is the only long international flight 10 hours that served a night grate dinner and the crews got disappeared the rest of the flight and no breakfast."

Pros: "I liked the care, the kindness, and the help"
Cons: "n/a"

Pros: "At least the entertainment systems worked this time."
Cons: "I've never thought that airplane food was bad before, but they ran out of the main options and I was left with macaroni and cheese. It was bad."

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."

Pros: "Smooth"
Cons: "Pay for food"

Pros: "Considering it was a tiny aircraft the flight went very smoothly."

Pros: "Flight crew were friendly"
Cons: "Ground staff were terrible and the ground crew mysteriously disappeared. Air conditioning was not working on the flight while it was on the ground. All passengers sweating for an hour on the tarmac. Flight arrived 2.5 hrs late resulting in a missed connection."

Pros: "service, friendly attendants, amenities"

Pros: "The in-flight entertainment system in the headrest was very robust. My children remained engaged for almost the entire 16hr flight...the flight attendants were not stingy with the food or drink and even allowed me to get a beverage in-between the services to take my medicine."
Cons: "The baggage pickup in Beijing took forever! Over an hour after arriving at the baggage carrosel! My car seats were in two different places (on the belt and in an oversize area). On a minor note, I was unable to get a stamp in my passport after using the automated machine...sad...I would have stood in the line to get the stamp if I was told ahead of time..."

Cons: "The flight was as can be expected. That said, having liquid drip on you from the air vent above is hardly reassuring and certainly not comfortable"

Pros: "Was able to get on an earlier flight which was really nice. was pretty packed but all in fairly comfortable. Food and entertainment options could improve."

Pros: "That I was able to play it on my phone"
Cons: "Flight attendants passed by me without asking if I would like to buy lunch and when she finally she came by they didn't have anything else"

Pros: "Staff very pleasant."
Cons: "Entertainment options very poor considering it is a 5 hr flight. Hadn't realized that they actually made planes without a seat back screen these days! Too many people allowed to bring too much hand luggage on board. Significantly delayed the process of getting people seated. Also, anxiety levels of passengers increases when they start to realize they will have nowhere to put their luggage. Not the perfect start to any flight."

Pros: "When I finally got to the US Customs agents they were actually quite nice. This has been my experience with US agents in Vancouver and Philadelphia as well. Yesterday they were especially cordial, while at the same time quite professional. Made me proud to be a US citizen."
Cons: "Don't know what could be done about it, but the security liine was the longest I've ever seen. I've come home from Vancouver many times before, and most times I fly direct to the USA from YVR, where things are much better. Don't think it's Tornoto's fault.....but, yesterday's experience with the security line makes it unlikely that I will come back home this way again."

Pros: "Direct flight."
Cons: "Payable ''snacks'' on a 6 hour flight. Come on! Charge 20-30$ more on the ticket and serve a decent meal. Entertainment is lousy."

Pros: "The attendants were helpful The food was good"

Pros: "The first leg of the trip was great from Montreal to Toronto on wide body plane."
Cons: "The airport in Toronto where they crammed about 10 gates together in a small area with no air conditioning (it seemed). Also flight was delayed about an hour so had to wait in horrible conditions with no seats for a long time."

Cons: "Seats are awful no leg room. Old plane and food sucked. Horrible rude service. Will never use again."

Pros: "The crew was amazing"
Cons: "Nothing"

Pros: "crew was awesome"
Cons: "that people can recline their seats in coach. very uncomfortable and there's really not enough room to do this."

Pros: "The crew was very helpful."
Cons: "Entertainment was terrible."

Pros: "The flight from DC to Toronto was late around four hours and after we got on the plane We went back and we were waiting at the airport while get more fuel and which repaired the fault on the plane. so I was late for my next flight to FrankfurtSo I was put on a flight to Frankfurt with a connection in Lisbon.In the end, my suitcase was lost and I got it only two days later. Never I will no longer use AirCanada small planes !"

Cons: "Cancelled flight and didn't even tell me a reason. They couldn't even make reservation for hotel. Hotel sent me back to airport because i didn't have voucher which AIr Canada guys said they can't make one? Everything didn't make sense. And they told me not to come again. They took like... whole day to book another flight. And i had hard time understanding what they were saying."

Pros: "No protection from noise. Gave up watching movies."
Cons: "Better earphone"

Pros: "On the whole it was a pleasant experience despite the flight being late."
Cons: "I thought that the flight being delayed by almost 2 hours was terrible. That should not have happened."

Cons: "Very slow service"

Pros: "Nothing - they were immature, unprofessional, nervous, unhelpful, and visibly shaken by relatively side problems."
Cons: "The flight was delayed for hours but not technically cancelled, which the ground crew blamed upon the flight crew and vice versa. The failure to cancel caused us to be unable to rebook, and subsequent avoidable delays arising from Air Canada's ineptitude caused us to be two,days late for arrival. The problem was solvable with some simple rebooking, but the ground,crew failed to assist, then the flight crew, when we finally left five hours late, was Impersonable, unhelpful, uninformed, and utterly unprepared. It was a terrible, second rate, poor quality experience and I would not recommend Air Canada to anyone. Your airline needs serious training in Professionalism and responsiveness."

Cons: "Flight was delayed by 30 min"

Pros: "The service was good"
Cons: "There was no entertainment."

Pros: "The crew was very nice and accommodating and the flight itself was great"
Cons: "We had a 2 hour delay and almost missed our connection"

Cons: "There was no working charge for electronics."

Pros: "It was on time and the crew was very good"
Cons: "No entertainment. Why can't the seats have just a little more leg room."

Pros: "Very good individual entertainer system in seat backs of new boeing dream liner."
Cons: "Called in advance re special veg meal but they didn't have it at mealtime."

Pros: "Overall, it was a nice flight. The domestic and express flights had no food on offer (for free)..."
Cons: "Beyond the absurd 12 hour layover in Vancouver, upon my arrival in Atlanta, my luggage was lost. I'm still waiting on a call saying it was located."

Pros: "Crew was fine, should serve at least a cookie with the drink..."
Cons: "Didn,t like the service I received getting off the plane.. Cannot walk any distance..Didn,t order a wheelchair, because I didn,t know I had too. Asked for a ride on the golf carts, got told to walk around the corner, and one will pick me up!! Never saw one yet!!! Took awhile but managed to walk to the luggage, but had to sit for half hour with the pain in my legs.....No thank you Air Canada, next tine it will be different air lines....."

Cons: "I was not able to board this flight. And it was such a disappointment and a shocking first for me. I reached the airport and on being checked at the counter, I was told that I cannot board because I don't have a Canadian visa. It was shocking to learn that I needed visa for a 1.5 hour layover. The website should give a prompt or should share the requirements. And all my ticket money got wasted."

Pros: "The ground crew were always nice and friendly. They worked hard to deal with delayed flight, missed connection, and tight alternate connection. Flight crew were also friendly and helpful."
Cons: "Four-hour flight delay released in one hour increments without announcement -gate displayed "on time departure" for the duration of the delay. Our hassles were compensated with meager meal vouchers given too late, There was no pre-boarding on our flight (just one big cattle call) which made boarding with child and gear extra awkward,"

Cons: "The flight was 3 hours delayed and we were not kept informed. In fact, the airport boards still displayed that this flight was on time, which was not correct. I kept getting emails of a change in schedule, but no reason was given by personnel at the gate. This was really a bad situation for me as I was meeting my daughter in Toronto who was flying alone with her infant son and she needed my help."

Pros: "Friendly crew and quick flight once we got moving"
Cons: "The flight left over an hour late with no real explanation as to why"

Pros: "Love the direct Air Canada flight from Montreal to San Salvador. In the past, there was a stop in Turks & Caicos but this time (19-26 April) the flight was direct. Please keep it that way... Thank you"
