Airline reviews

Pros: "The seat was ok... not too narrow neither too wide. All crews were awesone"
Cons: "Plz improve the foods and entertainments"

Pros: "Excellent crew. Very good food. Comfortable seats."

Pros: "Comfortable cabin atmosphere"
Cons: "For extra bag their website says $200 per 50 lbs I was charged $250 instead for 50 lbs excess baggage. Food was terrible and coffee served was cold."

Pros: "Nothing"
Cons: "Need improvements"

Cons: "The Nairobi airport experience could use a bit of help. there's no a/c and even late at night, it was uncomfortably hot everywhere. Once I'd checked in to the gate I was trapped and couldn't easily leave to get water or go to the restroom, which was increasingly annoying as my flight was delayed. Pretty sure all of this is beyond Qatar Airways' ability to control."

Pros: "Crew was excellent. Really helpful people."
Cons: "Seats are so tight and close to each other."

Cons: "Best flight ever and I recommend to have it again in the future"

Pros: "Plane quite empty so lots of space."
Cons: "Service not very attentive, had to repeatedly ask."

Cons: "More refreshments"

Pros: "The crew was polite and professional. The seat was as comfortable as it could be for economy."
Cons: "No complains. Qatar has always been my preferred airline."

Pros: "I liked everything. Plane ride was nice and I felt welcomed. Had a good experience."

Pros: "Q Suite business seats are the best with excellent service & delicious variety of meals."
Cons: "Nothing. Every thing was great!"

Cons: "The boarding system is somewhat confusing with 5 different zonings."

Cons: "Entertainment on the Boeing 777 suffered from access problems"

Pros: "Plenty of beverage service and food was very good."

Pros: "Nice new plane. Good seats. Good seat space between you and person in front of you."
Cons: "Nothing."

Pros: "Awesome leg room in economy. Helpful staff."
Cons: "Main courses weren’t all the great."

Cons: "During check-in, I observed inconsistent application of rules with respect to hand luggage. My carry-on and laptop bag combined were 12 kgs and was told that I had to pay excess baggage fees. While, there were quite a few people on the plane whose hand luggage was clearly above 12 kgs."

Pros: "food ok, economy seats not too bad"
Cons: "old entertainment system. Tight connection and first flight was late, so we got bumped off our connection (they literally removed our names from the flight, even though we could've sprinted through the airport and made it if they waived the 20 minute before departure gate closure). It was an exhausting and long wait for the next flight and I did not think it was well-handled. Staying in a hotel is not a great option, because it takes 2 hours to get out of the airport, another 2 hours cushion to get back in time."

Pros: "Very comfortable flight and helpful crew"

Pros: "Nothing was spectacular."
Cons: "No lounge in Philadelphia took my Priority Pass. On the flight, the woman in front of me threw her chair back without asking and almost had hot coffee all over me. When I asked her to put her chair up, she got mad. She went to staff to insist she could put her chair back. I showed them that I was indeed in a back brace for a health condition and that I needed opportunities to move and shift, cross legs to release tension, etc. Staff sided with the rude woman, who, given the chance to move to an equal seat on the opposite aisle where she could recline, refused to move. I was very frustrated and have never been treated with such discrimination regarding my health concerns."

Pros: "The service on our flights was wonderful! Qatar is the best airline that I’ve ever flown on."

Pros: "Overall the flight went well. Flight attendants were attentive and boarding went fairly quickly and flight was smooth."
Cons: "The bathrooms ran out of water. Not a great movie selection and almost didn't have any choice for lunch."

Pros: "Quick"

Pros: "The service and food."

Cons: "My seat would not go back. The food was all carbohydrates and quite cool instead of warm. There was only one tiny piece of chicken in chicken roll."

Pros: "Punctual,taxied in time,generally food was good, landed twenty before time. There was head wind otherwise it would have landed earlier. Additional toilet may be considered. Thank"
Cons: "Additional toilet may be considered"

Cons: "USB port was not working."

Pros: "Everything very smooth. Staff delightful and always helpful!"

Pros: "Hosted services"
Cons: "Nothing"

Pros: "They do not provide hotel service even in a 11 hour layover saying the ticket is pomotional. If that is the case, why they sell tickets on promotion? Cheap mentality"

Pros: "food, crew ."
Cons: "entertainment choices for Hollywood movies are limited."

Pros: "Flight was good n easy"

Pros: "All around a great experience."

Pros: "Overall nice"
Cons: "Same as above"

Cons: "THere was no wifi"

Pros: "Great crew members. Very friendly and helpful. Qatar Airways is great about providing pillows, blankets, ear plugs and eye masks. Really good food as well."
Cons: "The seats were very close together. With the tray folded out it was right against me without being extended. Leg room was cramped."

Pros: "just enough time in Doha between flights. Not too long not too short!"
Cons: "Asian vegetarian food can be of better quality."

Cons: "Before our trip we called Kayak service desk with the request to reserve our seats. The answer obtained was that we should do it online. When we went online there were almost no more seats available so we decided to go to the check in counter in the airport. Although we were more than 3 hours in advance in the airport there were almost no seats available. We were very disappointed about this service, we never experienced this with any other airline companies..."

Cons: "- Airline changed flight and offered little forewarning for what was a material change (from 1 hour transit time to 9 hours) - Boarding process was inordinately slow with little attempt to move this along quickly - Service was halting at best"

Pros: "Good crew. Nice plane and amenities."
Cons: "Flight to was canceled due to engine issues. Flight home was canceled due to scheduling error. Issue resolved at check in, but caused stress."

Cons: "It was an older plane. It seemed smaller and we had no choice in entertainment"

Pros: "Staff courtesy."

Pros: "Left and arrived on time, meals were above expectations."
Cons: "Difficult boarding procedure."

Pros: "Considering how long it was, not much could have been better. It wasn't too crowded, so the seat next to me was free, which made getting some sleep easier."

Pros: "When we flew into Melbourne it was not a happy experience. Seats were cramped and arm rests wouldn't raise. The flight out, even though on the same model plane, was better. There was more room and we could raise the arm rests. For a 13+ hour flight that makes a big difference."
Cons: "Because the tickets listed the same type of plane in both the bad and not so bad flight, it is very hard to know what we're going to get. I'd love to be able to plan to avoid the bad experience, but if they use the same plane in two configurations, there isn't enough information to do so."

Pros: "Service was good."
Cons: "Need to provide more variety for vegetarian food. Cannot serve the same food for every meal on a long haul flight. Provide more entertainment options, more episodes of sitcoms, more movie options, more language options."

Cons: "They supposed to provide Wheel chair for my elderly mother in Law who had a foot fracture, was very hard /painful to walk. I confirmed the wheelchair option well advance before her travel date in Qatar Airways Web site. I got the confirmation also in the Qatar Airways Web site. I usually fly with my family as I have a big family with couple of children and elderly. I will never fly Qatar again, this was the 1st and the last fly with Qatar airways."

Cons: "Plane seemed old and not upkeep. Chair in front of me leaned back to 5 inches from my face, every time he moved, the tray fell. The air seemed to be off in the front of the plane. Was sweating. But when I went to the bathroom in the back, it was cold"

Pros: "it was ok."
Cons: "Crew allowed passengers in with no masks. Why do they write a boarding time on a pass? They started 15 min later. Then, "be fast, be fast, we are behind". Plane departed 20 min late."

Pros: "10/10 would recommend.."

Pros: "Nice smooth flight. Also lovely to be offered a drink and food. Although the quiche is not great. Wasn’t nicer last year"
Cons: "Maybe just change the quiche. Very dry"

Pros: "The crew was polite and helpful. The wine was free and each seat had it's own screen with a good assortment of movies and TV shows."
Cons: "The food could be much better. Although coming from Sicily it's tough to compare."

Cons: "There was only one agent checking in business class passengers until a bunch of us complained. The Swiss business lounge is too small with not enough seats"

Pros: "The crew were very friendly."

Pros: "Flight was on time. Friendly crew and professional."
Cons: "I ordered vegan food, no meat , dairy free. On my trip from Boston to Zurich I received vegan food. On my way fro Zurich to Belgrade I was told” sorry we do not have any vegan food, “ Also, I was charged $60 for my check in one bag,. Not expectable."

Pros: "Service and food were good considering it was "plane food". No delay whatsoever."
Cons: "Black box under the front seat. No room for legs. Seat blocked in lower position, impossible to make it stay in upper position. Entertainment wasn't working good: extremely laggy when it was working ... Seats are way too short. You got the neck support into the upper back ... And I am only 1.80m. Overall, I am done with Swiss until they upgrade their planes. Wifi was 99usd for 220 mo ... what a joke. A 20+yo plane for a such reputated company. There was still the ashtrays inside the restrooms."

Pros: "Everything was perfect"
Cons: "Everything"

Pros: "N/a"
Cons: "I purchased ticket for my mom with one stop and they cancel that flight and gave her alternative flight with 2 stops.Not cool since my mom is olderly woman and not able to change so many air crafts."

Cons: "Our flight to Zurich was canceled and we had to take 3 flights to get to San Diego instead of 2. It was a huge headache. None of our flights were even with Swiss."

Pros: "I loved the upgrade to business class. It was private, spacious, and very hospitable."
Cons: "N/A"

Pros: "On time and a lot more roomy then the flight from New York to Zürich"
Cons: "There were no TV screens to play games or watch shows"

Pros: "Good product"
Cons: "Seat had some problems, but the crew fixed it for me"

Pros: "The TVs we’re newer and had a great entertainment selection available for a 12 hour flight"

Pros: "Crew helpful. Seats comfortable. Slept most of flight."
Cons: "Didn’t bother me because sleeping but much of flight apparently the entertainment system had issues"

Cons: "We (parents) were business class, but our two kids in coach, yet Swiss doesn’t allow “guests” in the lounge. Hmmm. What a bunch of BS."

Cons: "Very little space- I thought I was in economy plus having paid extra for seat reservation. When person infrint put seat back it was very difficult to view screen"

Pros: "All good with this 1:20 min flight."
Cons: "Everything was good. Seats much better and bigger comparing with international flight what should have been opposite - on longer flight - more comfortable seats than for the five times shorter flight."

Cons: "We missed our flight going to Geneva from new York and so automatically lost the return portion of our flight. So had to totally rebook. The people at the Swiss air counter were not very helpful."

Pros: "The airline crews politeness & courteous comfortable seating were helpful on meal selection."

Cons: "I have just had the most unpleasant experience with Swiss Air and feel that anyone on FB should be very careful when dealing with this airline. I am a Gold Member of Star Alliance for more than 20 years and have flown dozens of times on Swiss and would expect courtesy and consideration in return for my loyalty to their airline. Their flight from Hong Kong to Zurich leaves at 00:15. I mistakenly booked this for Nov 9th instead of the intended late evening of the 9th which then turns out to be Nov 10th. When I discovered my error, I called Swiss at least six times to explain my error and ask if my son could stand by for the same flight on the 10th or even apply the amount to rebook the same flight the next day. ZERO flexibility or consideration. Missed flight, lose entire value. Start from scratch. Astonished that an airline that claims to be serving their customers would treat me this way. I travel through Europe at least 6-10 times a year from Asia. I will now route through Frankfurt, Munich, Paris, London, Vienna, Instanbul or even Moscow before ever going through Zurich again. I encourage anyone making travel plans to be very careful when considering flights with Swiss Airlines. Perhaps this treatment of a loyal customer explains why they went through bankruptcy already once."

Cons: "Not very much space for such a long flight."

Pros: "Flight itself was good, comfortable, staff were professional"

Pros: "It was on time"
Cons: "They lost my bag for 6 days. It was an absolute horrible experience. There was a disconnect between their outsourced baggage tracer company and Swiss. Will NEVER fly again."

Pros: "Crew is great and took great care of us. Flight was on time and that is always a plus."
Cons: "No entertainment on this plane, which is okay. But even the magazine is pretty lame. Food was ok, although not particularly substantial."

Pros: "Again, crew and food."
Cons: "I will only say that I am writing this review as we are sitting on the plane in Newark where we are waiting for our gate for a half an hour already and we do not know when we would get off board. And oh yeah... the flight was originally late for about an hour too! Simply unacceptable!"

Pros: "Great kosher food! Very kind attendants."
Cons: "not enough foot room."

Pros: "Na"
Cons: "Na"

Pros: "Friendly crew. Good food"
Cons: "None"

Pros: "It was a very short flight. Thankfully very short."
Cons: "I paid extra for extra leg room and there seemed to be no difference in leg room between business class and economy class."

Pros: "The thing I liked most was being offered water routinely. I think I had the options to have a glass of water six times on my flight. For some reason flying really dries me out - so I really appreciated that. The seats were more spacious than the average flights I take. There were lots of movie options. There was more than enough space in the overhead compartment. I"

Cons: "There is no question about check-in?? My ticket, booked through Kayak, did not state that no baggage is included. The Swiss air just said I should have picked it up from the booking and forced me to pay Euro 30, which I will claim back from Kayak. This is gross misrepresentation and on the same ticket flying a luggage was included."

Cons: "Nothing."

Cons: "It was good enough."

Pros: "The crew was fun, informed, and very helpful."
Cons: "The seat, the entertainment, the headphone jack, the food."

Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

Cons: "Plane was HOT"

Pros: "movie selection"
Cons: "I missed my lufthanza connection"

Pros: "everything"

Pros: "Food. Variety of entertainment. Flight had empty seats."

Pros: "Great service. everything was on time, or early. overall pleasant experience."

Pros: "Great service!"
Cons: "Breakfast and movie selection could have been better"

Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

Pros: "very professional cabin crew"
Cons: "The overhead bins are way too small, and they ran out of the vegetarian dinner option. There are no longer air controls for each seat, and the plane was quite cold."

Cons: "We were charged a rebooking fee by Lufthansa when customs searched luggage causing us to miss connecting flight"

Pros: "Crew worked very hard to accommodate us."
Cons: "Was seated in a section with many noisy infants. I could not sleep or even hear the entertainment system sometimes. Not the airline's fault. People should know better than to travel with infants. I felt sorry for the crew."

Cons: "The flight was over before I expected it!"

Pros: "the crew are exellent"

Pros: "Lufthansa certainly stands out above ALL American carriers"

Cons: "The crew we had was very impatient and irritated quickly. The flighy attendent name was Jorge. Starting at the beggining of the flight before we took of I asked him about the head phones. One child had one on tye chair and I asked him if its suppose to be on the seat or given later on. He said it will be passed later and then with a patronizing manner he gave another head phone set and said: "I guess we havw an emergency". On the flight, every time he with the food and drinks he just stood there next to me talking over my head with the passenger begind me. Very uncomfortable, especially when it happens 6 or 7 times. When asking what drink we wanted ( the first time), i replied apple and orange juicewith no ice. He replied, with a patronizing manner "this it European company, not American company. Here we don't put ive if you do not ask for it".The incident that bother me the most is one that involved my kids also. My daughter (3 years old) was a bit scared of the flight, tired and did not want to sit on her chair. We tried to keek her on the chair buy she started crying laying down on the floor infront of our seats. Jorge the flight attendant saw her and told me to put her on the seat. Not in a manner I expect out of soneone in the service industry. I told him we are working on it and we will have her on the chair as soon as we can. When I said that he got irritated and a bit aggressive. For no reason the situation became hostile. The flight attendent on the other side (do not know his name). Can over and asked us what we needed amd if we need help. I told the other flight attendant we need 5 minutes and he said OK. After a few minutes she calmed down. Anotger passenger asked Jorge what beer it is and he replied, with contempt, " its German beer, its good"."

Cons: "They forgot the luggage at Frankfurt."

Pros: "Good flight good seats smooth ride."

Cons: "Unhelpful and now luggage has been lost going on 3 days in same clothes"

Pros: "Nice crew"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"

Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."

Pros: "Excellent service from a very friendly staff. Wonderful entertainment options to pass the time on a lengthy flight. Couldn't have been a smoother experience."

Pros: "The direction"
Cons: "One flight attendant was rude to me"

Cons: "They cancelled the flight and did not help at all for rescheduling."

Pros: "Smooth and on-time."

Pros: "Limpio,"
Cons: "La comida mediocre"

Pros: "Friendliness of the crew."
Cons: "There is completely no free snacks, just drinks (excluding alcohol). The maintenance didn't sign some papers for the plane which cause the unnecessary delay."

Cons: "Food had little taste. Movies were not that current and selection was sparse"

Pros: "Crew was great!"

Pros: "No leg room"

Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."

Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"

Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."

Pros: "The full experience"

Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."

Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."

Cons: "High cost Toronto Airport meals and beverages."

Pros: "Not much of anything"
Cons: "Lack of in-flight entertainment, uncomfortable seating"

Pros: "The flight was good"
Cons: "Because I miss my flight"

Pros: "The flight crew were helpful and friendly"
Cons: "I was forced to miss my second flight because the first airplane malfunctioned"

Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."

Cons: "Our direct flight to Montreal was canceled due to mechanical issues. The rebooking process was discombobulating and we ended up arriving at our destination after the rerouting that was stressful and ensured that we lost a whole day of our vacation time. Our flight back the entertainment system in our seats did not function."

Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."

Cons: "no entertainment and poor seat selection"

Pros: "The flight crew were great and very accommodating."
Cons: "A majority of the passengers on flight either barely caught, or missed, their connecting flight due to this flight being so delayed."

Pros: "I had an aisle seat"
Cons: "The plane sat on the runway in Denver for over an hour because they couldn't figure out their furling situation. Many people nearly missed connections because of this. The crew never let us get up to go to the bathroom on an international flight because of some small turbulence."

Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"

Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"

Pros: "The on board entertainment was phenomenal. My kids LOVED that they could connect and play games with each other. The gate agents in narita were the sweetest people I've come across in a long time."
Cons: "Air Canada is pretty dang snobby for the most part. Im not sure when a rule was instituted that headphones can't be worn under 10000 feet, but my three children were targeted many times about their headsets... on the ear, boring kid headsets... and there were THREE adults around us wearing similar headsets that were not bothered. I am a single mother of three tired children and we were settling in for a long flight and I found the treatment very unnecessary and discriminatory. The food was pretty awful, lol. We ordered kids meals and none of my kids ate on the flight."

Cons: "Crew wasn't helpful and attentive, boarding staff in Toronto were blatantly rude to me, I watched as my luggage got handled aggressively, the plane was dirty with old food crumbs and such, my flight to Windsor got cancelled and accomadations were not met sufficiently."

Pros: "Flight was on time. Personal entertainment is very good and crew was great."
Cons: "Boarding is always a bit chaotic with the carry on bags. I am tall, so economy seats are always uncomfortable."

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

Pros: "Low price with big value. The food was great and service felt like first class. The staff was friendly, courteous, professional and accommodating! Definitely recommend and will fly with Air Canada again!"
Cons: "The long layover, 14 hours"

Cons: "We were very unhappy that the flight was delayed by 35 minutes in Munich causing us to miss our connecting flight by 15 minutes… We only had an hour to get through customs and get to our next flight that should've been accounted for by kayak"

Pros: "I like that Air Canada provides entertainment and its flight attendants are really good."
Cons: "I rarely fly these partner airlines without experiencing major delays, and the delays are always announced after I have cleared security, forcing me to spend hours at the airport. The claims of "weather" are specious: they don't fly enough planes and they don't properly maintain the planes they do fly."

Pros: "Online booking,boardong pass, alerts"

Pros: "Excellent crew"
Cons: "Economy seating is no longer designed to fit any passenger who is even slightly above average height."

Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"

Pros: "Eventually they got us there."
Cons: "They cancelled the sat flite. Little communication . Left us after 6 hours and 11 pm to fend for our selves with no luggage. No compensation. It was awful."

Pros: "Nothing"
Cons: "Customer service flight rebooking"

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: "Entertainment system was awesome. Flight was comfortable. Crew very friendly."
Cons: "Checkin staff at airport was not friendly. Airline cannot allocate seats together even though booking was done months in advance. seriously!!!"

Cons: "No monitoring of travel route"

Pros: "An Air Canada rep over the phone"
Cons: "Gate agent, zero entertainment (and no warning that we should download an app inside airport), poor food, flight attendant wouldn't bring coffee to us (made us go to the back)"

Pros: "Upgrade to premium economy with more legroom. Free movies. Good movie selection. Free checked luggage!"
Cons: "Check-in process at Denver counter rather slow. Gate information at Denver very confusing due to changes and lateness in displaying/announcing information."

Pros: "I enjoyed the entertainment option."
Cons: "Wish there were more choices for new movies."

Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."

Pros: "it was on time landed a few minutes early stewerdess were very nice"

Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"

Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."
