Not much… woman's bathroom was Disgusting at airport. AirCanada has become the worst ever. No respect at all for peoples luggage, throwing/smashing suitcases. Some employees need to find new jobs, their rude and not happy….. Not too mention AirCanada cannot seem to maintain any schedules at all… constantly changing flight times, gates, etc. It’s time that AirCanada either a) close the business b) replace all rude and luggage beating employees or 3) replace AirCanada’s upper management.. other words revamp it. I will drive and/or fly out of the USA for future flights until they get their company in order.

The plane was delayed, and we almost didn’t have the time to catch our connection flight

Cons: "Flight left an hour late. Cramped seat. Only one drink service on a 4.5-hr flight. Disappointing."
Pros: "The in flight attendants were very helpful and attentive. Boarding was quick and organized."
Cons: "The entertainment system didn’t work well to start, and then stopped working altogether 2 hours into a 5hr flight. The staff tried to fix it and were very apologetic, which made up for it. The seats were a little too hard for me. I was pretty sore by the end of the trip."
Pros: "The crew wasn't as nice as they usually are"
Cons: "There was no space to put any of your bags and I was only travell8ing with a backpack. The airplane was so tiny"
Pros: "Te tightest seat ever, and I'am 75 Fair treatment by the crew Seatwise am not looking forward yo my return in a month Food os fair"
Pros: "Boarding was OK."
Cons: "Very uncomfortable generally. No water on the plane. Cold coffee and tea. Just a bad experience."
Pros: "This was my first time flying Air Canada. Our flight was delayed by 4 hours because they had to deice the plane. Yes it was frustrating but I would much rather have a flight of upset passengers then risking our lives. The captains and the crew went out of their way to make sure that we were the most comfortable. They gave us food and drinks as we waited and were extremely patient. Upon arrival many passengers had missed their connecting flights, including myself. They put us on the next flight out and gave all passengers a hotel and meals for the night. I would definitely recommend Air Canada. The plane itself is also pretty spacious so don’t be afraid to fly economy."
Cons: "Nothing really. They were great. I mean, definitely wished my flight wasn’t delayed. Although It wasn’t their fault that they needed to deice the plane, that’s something that should’ve been accounted for way before our flight was supposed to take off."
Cons: "Very sub par service and you have to pay extra to reserve a seat."
Pros: "The seating was good and the pilot was friendly."
Cons: "There was not a good movie selection and there was not a lot of information regarding the altitude and there was not very much warning during turbulence."
Pros: "Very good flight experience"
Cons: "good planes, good services"
Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."
Cons: "They feel like seats for budget flights."
Pros: "Decent movies."
Cons: "I separated from my 2 daughters and husband because they did not allow me to pick seats or check in online. I was stuck in the seat immediately in front of the stinky bathroom in a seat that didn't recline, had no hdmi charging port and was pretty much continuously crowded by bathroom-goers. In fact, so many bathroom goers grabbed the seat in front of me that they touched my movie screen about 7-8 times, causing the menu to pop up and interrupt the movie. Otherwise, the food was gross and one of the flight attendants was very grumpy."
Cons: "Flight back to LAX was delayed an hour and a half. They didn't give us anything like peanuts, cookies, etc. like other airlines do. Just mediocre."
Cons: "For some reason we were forced to check our luggage (standard curry-ons) however it would completely fit to ovehead bins. Also waiting area were completely cut-off from Duty-Free shops - as soon as you passed security - no access to shopping area."
Pros: "The crew were friendly and helpful."
Cons: "The screens in front of the seats didn't work for everyone. They attempted to fix the system by restarting it, but the problem remained unfixed."
Cons: "Flight was delayed for more than hour."
Pros: "Smooth ride. Friendly and professional crew."
Cons: "Very uncomfortable seats. Wasn't able to recline seat because the passager behind complained that the seat was in her face."
Pros: "The movie collection is pretty decent. The food is decent and they provided snacks, etc as well. The stars is nice and I saw them helping out the parents who flied with small toddlers."
Cons: "There was 40 mins delayed because there is Toronto flight canceled and they tried to reroute those people to our flight. But a lot of these people have connection flights and we have to run through the long connections platform to get to the other side as well as go through the customs because it's the point of entry back from Rome."
Pros: "The crew members were also friendly"
Cons: "The boardung gate was changed but no announcement was made"
Cons: "The type of planes they use "Rouge" are too small, even for business class passengers. Seating & legroom is like upgraded economy, not business."
Pros: "Quick boarding, flight on time, nice crew."
Cons: "The only thing they serve is water. Still or sparkling. And chocolate bar. Anything else is paid. It's not low fare airline and this should not be happening."
Pros: "Boarding was smooth, considering there were just over two hundred passengers to manage. The crew was excellent: responsive, courteous and proactive. Entertainment: Overall plenty of options though some were dated. Food: surprisingly good, and COMPLIMENTARY. Didn't have to pay extra."
Cons: "Coach is CRAMPED. And on a 14-hour flight, that's important.."
Pros: "The crew was pleasant, and the boarding and de-planing process went smoothly."
Cons: "The plane was really cold, and we were told that they couldn't adjust the temperature, but we could have a blanket - at a cost. We have heard from other people who travelled Rouge about how cold their flight was, too. I also didn't realize that there wouldn't be in-flight movies - unless you rented an i-pad, etc. That was a bit disappointing for a 6-hour flight. I think that I would rather have paid a little higher fee for the flight and have some of the things built into the ticket than have to keep paying out money for all the different things."
Cons: "Hardly any space, 5'8 & my knees were hitting the seats in front of me. Attendant was unfriendly & neglectful. Somehow everyone got a drink except for me, then when asked for a glass of water it never did come... Made me check (my only) luggage upon boarding because attedant said it was too large... meanwhile I've traveled around the world with this exact same carry on luggage, never without a problem. Had to then wait 30min to get my (only) bag upon landing."
Pros: "air canada quickly changed me to another flight when mine was delayed but I had to ask for that, they did not offer."
Cons: "delay was long and I wasn't offered a switch to another flight. had to ask myself for it."
Cons: "My flight was cancelled, re-scheduled 8 hours later. No notification on Air Canada was given. They mentioned that "this flight never existed" I had taken a day off of work to be there and I also had a meeting, however, my flight had been cancelled. Also, the costumer service representative mentioned that if I left th airport, they would not let me back in. They would do 2 security checks on me. After all of that! When I asked the check in lady at air Canada they mentioned that flight was not cancelled and not to look at the boards at the airport because they are incorrect! Horrible service. Horrible experience."
Pros: "I love Air Canada's willingness to change my flight at the last minute since there was room on the plane. It was great to get home earlier than I expected."
Pros: "B777-300ER AIRPLANE ITSELF"
Cons: "SERVICE, ENTERTAINMENT"
Cons: "Pearson airport transfer was hellish. I felt like I walked five miles between flights, and then had to go through the whole security process again, causing a missed second flight. This transfer of flights was not booked with sufficient time between them given the long distance walked and the slow security process. I will avoid this airport in the future"
Cons: "On both outbound and inbound trips (connecting with international flights) the flight was late. Both times the door was closed and then they informed us of the delay. I understand that smaller planes often get bumped, but on the outbound leg, a 20 minute delay on the tarmac and then not allowing us to deplane for another 15 minutes meant I missed the connecting flight."
Pros: "Served edible food (not the best quality)"
Cons: "Uncomfortable; No source of entertainment; No functional charging ports; charges for snacks; some staff seemed rude"
Cons: "On the way back from Quebec City to Montreal we were asked to check our carry-ons as luggage, because "there is no room' on the plane. It was an empty flight. ALL overhead compartments were empty. Both flights - Quebec to Montreal and Montreal San Francisco were late. As the result, we have to spend 1.5 hours in the baggage claim area, because "there are no baggage agents in SFO available". THAT WAS THE WHOLE REASON WE ONLY HAD CARRY-ONS! By far, one of the worst flight experience in the last 10 year."
Pros: "Nothing"
Cons: "Absolute joke of an airline with zero customer service. I would never travel with them again and would recommend anyone else not too."
Pros: "Its entertainment"
Cons: "very uncomfortable coach seats and 4 hour delay in Vancouver airport"
Pros: "Air Canada did put us up in a hotel for the night when they cancelled our flight."
Cons: "The airport was so crowded that we couldn't get a flight out of Munich to anywhere else."
Pros: "Staff was professional and courteous. The staff was helpful but were too busy dealing with the full plane load of passengers."
Cons: "Crowded middle seat that was uncomfortable to sit in. Sat next to severely overweight person, who needed two seas to be comfortable. I was squished. The seat belt was tangled up and I could not fix it to adjust it. Bell to call flight attendant was not working. The middle light bulb was burnt out. Took my book to read on this long flight but could not read. just sat in the dark when the lights went out. Boarding the plane seemed like planned chaos! No one (passengers) listened to instructions and these were poor given by those responsible to oversee the boarding the plane. Fight was delayed for half an hour with people coming on at such late time. Had to change seats to accommodate others - family with children. Dealing with disembarkation should be better and much too long. Those with connecting flights should leave first and can be identified earlier to prevent cheating. Those with children should be next. Those in the aisle seats then leave, followed by those in the middle and window seats. Loading the plane after the business class or first class should be according to seat number from the back of the plane to the front. this completely random boarding boarding clogs up the aisle with passengers and luggage. I thought in an emergency this plane would not be efficiently evacuated. You can call me Seelochan Beharry 604-261-6690"
Pros: "on time"
Pros: "Take off and landing"
Cons: "Non reclining seats for such a long flight. Very little leg room and indifference of flight crew."
Cons: "Again, more delays."
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: "Boarding was on time, flight was smooth and the service was great!"
Cons: "I don't have anything negative to say about this flight!"
Pros: "the boarding process was smooth and organized."
Cons: "food should be part of the ticket and not extra payment. In a 5 to 6 hours of flight there should be at least some snacks offered."
Pros: "Nothing"
Cons: "first flight cancelled, second flight delayed so impossible to get the connection. Nobody called me about it, I had to go to ask."
Pros: "Entertainment choices on this flight/with this plane were endless, and you didn't have to pay extra for them like you do with Condor, for instance. The seats were relatively comfortable, in comparison to the way you are packed into some planes these days. Particularly liked the headrests that were adjustable side to side. It helped in this particular case the flight wasn't completely full, and so I had the seat next to me free."
Pros: "Skilled pilot dealt with rough weather very well."
Cons: "if you have ever flown on a low cost airline like Ryanair or Easyjet act like you are on that flight. Bring snacks and headphones."
Cons: "They charge for movies."
Cons: "My passport was still valid but didn't have the 3-6 months left on it (a rule I didn't know about) and was told about this at the air canada counter without any concern or direction. Was in shock."
Pros: "The flight attendant was well informed and quite helpful."

Great flight, friendly crew and always on time

Cons: "Disastrous rescheduling"
Pros: "Big selection of movies if you have the United app."
Cons: "Tiny overheads in the 777 so they took carry-ons from at least half the people on the flight. Out of the hamburger by the time they left Economy Plus. Narrow seats, very little seat pitch. I am not quite 5' 10" and I only have a couple inches between my legs and the seatback. Similarly cramped restrooms."
Cons: "food"
Pros: "Crew was ok"
Cons: "Had to wait in plane for over 1/2 hour coming and going to Denver!!!"
Cons: "Several delays for maintenance and then plane in our gate when we landed"
Pros: "Great price — easy flight. Had an entire row to myself, so I could stretch out."
Pros: "I enjoy the plus seats with extra leg room"
Cons: "I found your crew quite unfriendly"
Pros: "Check in and bag check were easy and fast. Kiosk system works well. Excellent entertainment offerings!"
Cons: "I realize there is no real food service in coach, but a little variety in bagged snacks would be nice."
Pros: "Flight was quick and uneventful."
Cons: "50 minutes wait on the runway in a very small plane. No room for carry ons"
Cons: "No screens in seat back; WiFi not working"
Cons: "my reservation was cancelled by united with out checking with me."
Pros: "Nice flights attendants"
Cons: "This is not how business class sshould be"
Pros: "Nothing"
Cons: "Overbooked, delay in de-planing and getting luggage"
Pros: "The crew was nice, quick check ins and boarding. They were very accommodating during the flight."
Cons: "Although it was breakfast, not everyone wants sausage or the other option of fruit and yogurt. Meals should be offered in the literature provided by time, as in reality, if you're not going to sever the expansive US menu throughout the day. I was unable to order a salad at 9 am, regardless of being starving. Also I'm 5'1, there isn't enough leg room. Power outlets should not be a first class luxury, that is rediculous. We all need to charge our devices. TV should not come as an extra charge."
Pros: "I like the price and the time of the flight. Thank you"
Cons: "N/A"
Cons: "The food options are poor at best and it's really sad that they don't offer anything for free. My ticket wasn't cheap so I can't imagine they're saving me money on my ticket by not offering better food on that long of a flight. Especially lacking in any gluten free options or anything resembling healthy. A small thing of fruit that probably has 70 calories is not enough to sustain someone on a near 8 hour flight."
Pros: "I liked that it was a fast flight arrived ahead of schedule."
Cons: "Seating was crowded."
Pros: "On time Nice crew No complaints"
Cons: "Pure sugar snack"
Pros: "On time, easy boarding. Good storage room for carry-on luggage. Clean, great new aircraft."
Cons: "Not enough beverages served during long flight."
Cons: "That I never made it to Dallas and so lost my job. Thanks to unitrd."
Cons: "Severe delays. Disorganized boarding procedures. No internet."
Pros: "Friendly staff, smooth flight"
Pros: "Smooth boarding. Arrived at designated time"
Cons: "Really only a snack pack and water."
Pros: "Nothing"
Cons: "Departing flight was delayed, United could not get me to Richmond before 5 pm. Not acceptable. They had to book me on another airline. Never took the united flights."
Cons: "They cancelled my return flight when I rebooked through united online."
Pros: "The flight was delayed for who knows what reason and after many it's gonna be right here! It took an hour and therefore delayed my arrival to my final destination 6 hours!!!"
Pros: "That I made it alive"
Cons: "That the seats were very small and the person next to me could not fit into their seat"
Cons: "Fligh delay."
Cons: "Ok for a short flight"
Pros: "Horrible"
Pros: "The boarding was quick and efficient. The crew was super friendly."
Cons: "The plane is old. It lacks entertainment amenities. Bolt Bus and Grayhound are luxurious in comparison to this United plane."
Pros: "I had a comfortable flight it was on time the people were congenial everything was good."
Cons: "Kayak did not notify me 24 hours in advance for my flight itinerary. I was a little disappointed in this."
Pros: "Crew was friendly."
Cons: "My flight was delayed twice on both the trip out and the return. It's not such a bit deal for a longer flight, but when the flight is barely more than an hour and it's delayed for an hour each time it really starts to negate the point of flying instead of driving when you factor in the airport time."
Pros: "Everything about this flight was satisfactory."
Cons: "Having to pay a baggage fee for the one bag I checked; lack of seat/leg room."
Cons: "The snack offering was not appealing. I understand nut allergy sensitivities but the option was poorly decided."
Pros: "Very nice that my husband and I were upgraded to first class on this short flight. It was a short flight but we were very comfortable for that time."
Cons: "I'm very upset I left an item in the overhead bin and had customer service call over as soon as we realized, but they said it wasn't there. There's no way, it had to be there and they didn't look very hard. I submitted a claim and they still haven't found it."
Cons: "No beverage service, glass of room temp water, no ice"
Pros: "This was one of the top 5 worst flights. I have over 150k of miles logged. I will do my best to NEVER fly United again."
Pros: "The crew kept you up dated, and they were caring."
Cons: "I loved it all"
Cons: "The crew was very unfriendly. I was extremely shocked how they seemed to be bothered when called upon. I boarded group 3 and by the time I got to my seat overhead space was filled all around me. My seat was row 32. Im not one for speaking out but this was a very unpleasant experience."
Pros: "I was in a wheel chair and the crew in the airport made my transitiins within the airport very easy"
Cons: "."
Pros: "Nothing"
Cons: "Dad services they don't care about the passengers"
Pros: "Quick load and exit"
Cons: "Small plane. Dozens of bags taken in jetway so a long wait for delivery. Rough ride throughout"
Pros: "Price looked good at booking."
Cons: "Old prop plane was grounded 5 min. after our boarding time. Went to several gates to try to hop on another flight but nothing got me to my destination in time -- so a total loss. Tried to cancel by phone (line to gate service was 50+ people deep), and was told I couldn't cancel. Then was told I could. Then was told I had to call back! TOTAL LOSS. Refund is needed."
Pros: "Patrick- flight attendant"
Pros: "Nothing about it"
Cons: "Everytime I fly United there is ALWAYS a delay. I will never choose to fly United again. I had two flight which were both delayed, very upset about it."
Pros: "Nothing"
Cons: "No running water in the bathroom. No space in the overhead compartment."
Pros: "Easy boarding , good leg room. Two seats rather than three to each side."
Cons: "No entertainment or headsets"
Pros: "R flight was cancelled and did not fine out until we were at the airport.."
Cons: "That r flight was cancelled and there was no other flight"
