Cons: "They loose my luggage!!!!!!"

Cons: "The train at Chicago airport was broken. I walked to get the next gate to the other terminal."

Cons: "The flight was delayed I had to wait for more than an hour"

Pros: "There wasn't anything that stood out that I could say I liked."
Cons: "I didn't care for the attitudes if the stage working in the Toronto airport. Things really aren't clear there for first-timers and much of the staff was acting like I should already know to do a lot of things when there weren't any clearly posted signs saying so. There is also a huge lack of organization."

Pros: "Upgraded to business class."

Pros: "I got upgraded to first class!"

Pros: "Extremely helpful and accommodating! Thanks to all!"

Cons: "The seats are large, but they tilt forward. I'm 6'2" and have anxiety issues related to spinal problems. That forward pitch in the seat (half way up the seat) is an painful problem for people like me."

Cons: "Departure was late, causing me to have to run to the next gate"

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: "We were walking towards our seats near the end of the aircraft when this flight attendant stopped us from loading our hand luggage in the overhead bins. She made us stuff them under the seats in front of us. There was space im the overhead bin, but there was a bunch of stuff that belonged to the cabin crew. Rude."

Cons: "See above."

Pros: "Long wait for ticketing and at customs during transfer"

Pros: "One kind guy at air Canada in Toronto who was very helpful considering the lack of help from every one else. Arrived at 2 in morning exhausted."
Cons: "Attitude of staff"

Pros: "The pilot seemed good and the staff on the plane were nice overall"
Cons: "Customer service from the group staff that checked us in was horrendous... (Lisa from Chicago ). We were not aware one of us needed eTA to fly through Canada and the agent was so belittling, rude and plane wrong with her information, that if it had not for our smarts, we might have not made it to our destination. I do not spend so much money to fly with an airline, whose agents treat it me like this! She really should be fired for her terrible manners and for giving customers wrong information..the second supervisor we talked to helped us, but the impression we got from the agent was so terrible, that it was hard to feel any good...no food on a flight during lunch hour, seems unfitting."

Pros: "Crew"
Cons: "Boarding gate very small"

Pros: "I liked that we got a lot of food, and the movies were very good. Groups for boarding made sense and we boarded quickly"
Cons: "it was late and despite being 4.5 hours there were no free snacks or food. Only one toilet which we could never use bc of constant turbulence."

Pros: "The ever wonderful Air Canada cancelled a bunch of the flights that I had originally booked 2 months before I left and marooned me in the Toronto airport for an 8 hour layover on my way home. Unacceptable. No reason given, no apology made, nothing."

Pros: "Poor airline, always delayed, dreadful and unfriendly customer service. The only reason I flew with them this short trip was due to price"

Cons: "My flight was changed and I wasn't informed - I cleerly checked my information beforehand but it would be nice if flights were to change by two hours, to know in advance so arrangements could be made"

Pros: "Nothing"
Cons: "Flight was late from Barcelona to Mintreal by an hour. I needed a wheelchair - didn't show up! Then pulled a muscle trying to get through customs and they barely held my flight to Chicago. Made it, with No Help. Late into Chicago and still no wheelchair. There was no one from whom to get help. Finally a United Airlines employee took pity on me and got a wheelchair to me and got me to the flight - again, just barely. Over 20 hours in the air, no assistance and poor food. I will never fly air canada again - ever. Not worth the savings. I've spent an entire week recovering and spent the savings on physical therapy due to the damage to my legs."

Cons: "horrible"

Pros: "short trip"
Cons: "delayed but didn't update the screen as delayed even though it was delayed an hour it still said on time."

Cons: "Delayed"

Cons: "This is the third time that I flight with Air Canada and the third time that my flight got delayed. Never again!"

Pros: "Plane was super old...peeling paint, barely any full size luggage space, no in flight tv and always late or delayed. 4/4 flights we took were delayed. This airline is the worst and were terrible at keeping us updated on delays or cancellations."

Pros: "Staff was friendly"
Cons: "Uncomfortable seating"

Pros: "Everyone I came in contact with was amazing and super helpful!"

Pros: "Despite weather travel delayed I was taken care of very well. Comfortable seats. More leg room. Friendly, calm crew."
Cons: "We were not given the option to change our flight out from Chicago when we knew we wouldn't make the connection in Montreal due to weather."

Pros: "The plane was new and pretty clean"
Cons: "Food was horrible. Crew was useless. No organization."

Cons: "The departure time for the flight was 6:00am and there was no one in the check in counter until 4:15am. There was a long queue for the check in. Not a pleasant waiting time for the check in"

Cons: "The engine was making an unusually loud whirring sound. Felt concerned that the plane was not fit to fly."

Pros: "The plane was delayed and I had a short layover so I was maybe not going to make it to my next flight so they transferred me to another airline and was upgraded to first class for free!"
Cons: "I disliked that my flight was originally at 4 pm and the one that I was changed to didn't leave until 8 pm"

Pros: "Quick flight"
Cons: "Delays"

Pros: "The food was very good, and the alcohol was free even the second time around which i liked"

Cons: "Not enough time to go through customs. Missed connection."

Cons: "Deplaning and entering the terminal was delayed substantially."

Pros: "Provided a blanket and pillow, breakfast and dinner, had 3 bathrooms which was excellent for how many people on the plane. The flight attendants were excellent and very nice as well. I do love air canada for long flights."
Cons: "When i checked out the cabin after i bought the tickets i was under the impression that there would be screens on the plane to view movies for free. Instead they were offering for $10 to buy a ipad and more money for headphones to rent for the flight to watch movies. Kind of was a disappointment but i read a book which is always better to do anyway."

Pros: "The crew was very nice."
Cons: "It was like flying in 1995. They may want to consider buying more modern planes."

Cons: "No free alcohol. Lights didn't turn off ever so I could get some sleep."

Pros: "the crew was great, food was alright, and overall I enjoyed my flight"
Cons: "the only entertainment was able to connect to apple products or a renatble iPad. I don't have an apple product so that was a bit annoying"

Pros: "The crew on the flight was nice, and the entertainment was good."
Cons: "Our first Air Canada flight was 2hr delayed due to mechanical error. After a 2hr delay, we finally flew for 1hr, had awful turbulence on the way down, and got to Toronto only to find out there was no customer service desk. We missed our connection with Luftanza and had to fly Air Canada again. First off, we couldn't get on another flight until the next morning. Then the desk never called the hotel they gave us the voucher for, so when we showed up at midnight the hotel was fully booked and had no room for us. We had to fly into Heathrow instead of Gatwick (final destination was Brighton for an international conference). We missed the entire first day of the meeting and had to rent a car for 65 pounds each to take us to Brighton from Heathrow, finally arriving at our hotel by midnight. The customer service was non-existent for Air Canada. We literally are going to have to email them."

Pros: "The flight was comfortable. Entertainment choices were varied and generous."
Cons: "o'Hare needs an upgrade."

Pros: "How quick it waz"
Cons: "How close the seats were"

Pros: "I liked the way they handled the rain delay. Although inconvenient, they were transparent with the process"

Pros: "On board service Comfortable seating and space On time dep. & arrival"
Cons: "None"

Cons: "Long delay because the catering company forgot to replenish the aircraft."

Pros: "I like having the trip map in front of me so I can track progress. Usually I don't get it on flights this short."

Pros: "The crew was friendly, there was entertainment available via the display on the back of the seat."
Cons: "The touchscreen display wasn't working properly, making it difficult to control things like volume. I would have preferred a display with physical buttons that took a bit more time than the weirdly synced touch screen"

Pros: "Nothing"
Cons: "Bad airline delays change gates horrible not recommended"

Pros: "love when they turn off the lights"
Cons: "annoying late notifications of gate changes"

Pros: "Efficient"
Cons: "Free wifi"

Pros: "Everything"
Cons: "Perfect"

Cons: "Screaming babies the entire time"

Cons: "Free WiFi kn the plane was hardly working even over US mainland, before it list connection with outside internet over ocean. But it is something I do not care much about."

Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."

Pros: "Getting a meal and drink"

Pros: "One attendant did it all. And very well. Impressive."
Cons: "More snack options."

Pros: "I liked the tv and movie options on the United app but thought the movie selection could have been better."

Cons: "Not here as long as the last place but was still teribly confusing. The airport is not very new user friendly. I had to ask ppl multiple times where gates were and issues with time changes etc. Was pretty nerve wracking for a first time traveller to the states."

Pros: "yes"
Cons: "the plane's seating"

Pros: "Everything from ticketing to deplaning was smooth and professional."
Cons: "No problems at all."

Pros: "On time"

Pros: "Having about an hour and 20 minutes left me with enough time to explore the airport from one gate to the other without feeling terribly rushed."

Pros: "Not much"
Cons: "The food not fit for human consumption"

Pros: "Quick boarding. Ontime departure."
Cons: "Very small servings of food."

Pros: "comfortable and on time"

Pros: "Happy people"

Pros: "Dr usus I"
Cons: "The keys"

Pros: "The seating was comfortable. On the Chicago keg I was seated in the middle and was not stuck with people who were too big for the seat. I noticed there was an overweight person in first class. Does United have strict policies on size?"
Cons: "Just the fourth seating group had trouble finding a place for my roller board carry on."

Pros: "boarding very easy"
Cons: "no drinks ir snacks offered"

Cons: "Very uncomfortable plane!"

Cons: "Lines"

Pros: "The gate at the Chicago airport was well designed. There was a line for each boarding group, and you could line up early. This is particularly effective for some Asian flights, which can sometimes be chaotic with many different nationalities all lining up."

Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."

Pros: "We'll coordinated."

Cons: "See above comments."

Pros: "Great"

Cons: "Lost my luggage"

Pros: "Same as above"

Pros: "Every one was friendly. The plane was clean"

Cons: "They didn't have wifi"

Pros: "no complaints"

Pros: "Was never in Chicago."
Cons: "Was never in Chicago but my stuff was."

Pros: "Perfect, but I did upgrade to United's business plus."

Pros: "Aisle seat."
Cons: "They made my dad check his bag even though there was space."

Pros: "Worst flying experience ever"

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: "I got there on time"
Cons: "Why not have people board the plane based on sat number? Why this cattle call and stand in line like you're not going to get a seat? Everyone fighting for line position so they can get a place in the overhead bins? Stupid."

Pros: "Please address the lax enforcement of one carry-on and one under-the-seat bag/passenger."
Cons: "Overhead compartments were full by the time I boarded so my bag was taken and tagged, as was several other passengers. I noticed upon arrival in Hartford that several passengers had 2 bags in the overhead compartment and their coats as well. If you have a policy of one carry-on and one under-the-seat/passenger, why isn't this enforced? It is not fair to the Group 4 and 5 passengers that there is no room in the overhead compartments and they are forced to relinquish their bags. Furthermore, this results in them having to go to the baggage claim area and wait for their carry-on. This added a half hour to my time and my ride had to circle the airport waiting for me to come out."

Pros: "Overall I arrived at my final destination in one piece. I'm satisfied :)"

Pros: ":("
Cons: ":("

Cons: "The airline checkin is terrible and time consuming!"

Cons: "Never made it because of stupid United"

Pros: "The pilot got us there safely. Good deal of turbulence."
Cons: "Stewardesses were rude to many. Chit chatted with each other whole way, ignored passengers. "Too turbulent" to serve us a beverage, which was okay. Except first class got full service. Wrong."
