Airline reviews

Pros: "Crew was fantastic!"

Cons: "It’s very very poor and flight radar is below average"

Cons: "Multiple technical issues on each leg of the flight for both airlines. Took 1.5 hours to deboard the aircraft on final leg of journey"

Pros: "Free wine!"

Pros: "Seats were spacious and they fed us on the flight."
Cons: "In flight entertainment."

Pros: "Everything was good."
Cons: "No major complaints."

Pros: "Not much compare to other airlines"
Cons: "Food!"

Pros: "Very comfortable. All very nice."

Pros: "Lufthansa will always be my choice airline. Their staff are nicely dressed, accommodating and well mannered."
Cons: "On this trip back to Dublin, our flight from Munich to Dublin was delayed for over two hours. It would be nice for Lufthansa to at least offer the passengers something to eat or drink while on board waiting for such a long time."

Pros: "So very comfortable with lots of room. The mattress pads for the seats were a nice touch."
Cons: "Food was mediocre."

Pros: "The food selection and quantity were wonderful! The crew and movie selection were great!"
Cons: "My seat storage pocket was broken and I was unable to store items in it."

Pros: "The service on board was excellent."
Cons: "Boarding got a little bit chaotic for families with small children."

Pros: "All the full service airlines are pretty good in the air. But what sets apart Lufthansa is it's ground staff. On the previous occasion I had left behind my waist bag on the seat containing passports, cash and cards. Their lost and found desk retrieved it quickly, absolutely intact. On the last occasion, my mother in law, who is over 85 was taken care of very well at not only Delhi but especially at the Frankfurt airport. I must truly acknowledge young lady Jessica's efforts, in ensuring that everything was handled very caringly by her personally, for an old lady at the Frankfurt airport."

Pros: "The crew, both in SFO and on board where e excellent. We were well taken care of, in both area's. The service on the plane were top notch, anticipating our every need. The food was yummy and the entertainment great!"

Pros: "The crew again was great. The cheese sandwich was also excellent. I wasn't expecting a sandwich on a 2 hour flight and this was a welcome surprise."
Cons: "Boarding took a long time, but that was a product of having to bus everyone out to the plane for boarding. They also crammed way too many people onto the bus. Would have been more efficient to load quickly and go as another bus was already waiting."

Pros: "Excellent service and food"

Cons: "Bathrooms rendered unusable by kids putting everything imaginable down the toilet."

Pros: "It was a short flight."
Cons: "I was allergic to ingredients in the in-flight meal. There were no additional options left by the time food got to me. The crew was indifferent about my allergy and seemed offended when I returned the food uneaten."

Cons: "The connecting flight to Bremen from Munich was missed due to delayed flying from Munich. Then we had a reconnecting flight and 15 minutes prior to boarding it was cancelled. No more flights to Bremen so we then were redirected to a flight to Hamburg. We had to fly from Munich to Vienna and then from Vienna to Hamburg. The flight from Munich to Vienna was delayed by 40 minutes which made us lose the connecting flight. We had to wait until the next morning for a flight to Hamburg, where as we arrived our luggage was lost. The staff ensured us that our connecting flights were waiting for us, however the flights had left 20 minutes prior to our arrival. The staff was nice but the communication was poor."

Pros: "Short flight with efficient service and coffee"

Pros: "friendly service"
Cons: "no head support"

Cons: "50 minutes late"

Pros: "Nice to be on a full service airline for once"

Pros: "Great flight and a super smoth landing in strong southerly winds."

Pros: "Staff mostly, but also plane, seat, food, boarding and communication."
Cons: "We left late due to weather — which is okay— but pilot didn’t catch up in the air. Also, the connection was tight partly because the Prague flight parked at the far end of the field and the bus ride took forever. Then we had so far to walk to get to the departure gate."

Pros: "My flight from Budapest took off hour later then scheduled. We landed in Munich only ten minutes before the international flight's take off to San Francisco. Upon the Munich landing, eight of us were escorted on a special bus, with a special pass controll and on special routs to make sure we get on the plane on time. Our laggage managed to get on the same plane as well. Thank you Lufthansa!"

Pros: "Boarding was fast"
Cons: "I had to pay extra because I didn't know that Lufthansa only allows one piece of luggage for international passengers, unlike most of their competition. Cost me $375 extra!!!"

Cons: "Guy next to me died. Emergency landing. They refused to hold the gate for my connection in Frankfurt for 15 minutes."

Cons: "Walk between connecting flights in Munich was very long (25 minutes) and when we got to the gate for the flight to EWR, there was a very long, and very slow-moving line with only one attendant checking boarding passes for 6 gates. We arrived at the gate and were among the last passengers to board. A last minute additional attendant that was brought on, helped to make the line move a bit faster, but this under-staffed checkpoint added unnecessary stress to our long travel day."

Cons: "Movie screen is outdated and touch screen didn't worked for me to select movie. Screen for flight status was showing flight from Mexico to Germany. We did fly from Germany to Chicago."

Pros: "Staff was nicer on this flight verus the first flight."
Cons: "My tv didnt work. They tried to reset it twice. So 9 hours without entertainment sucks!"

Cons: "N/A"

Pros: "service on luthansa was delightful"

Pros: "Attentive crew. Smooth flight!"
Cons: "All good"

Cons: "Lufthansa sharing code with United wasn't pleasant at all."

Cons: "Because of mechanical errors in our point of origin (NJ, USA) we were unable arrive on time in Germany to make this connecting flight. Very very disappointed in United Airlines. Will never travel with them again."

Pros: "Flight was on schedule, food was good."
Cons: "Could add more to the entertainment list"

Pros: "Good service"

Pros: "Extremely roomy seats! So glad to have the room after a cramped flight from Europe!"

Cons: "I will not fly on Air Canada again...Eventhough this is listed as a Lufthansa flight there was nothing Lufthansa about it. Terrible food. Overall miserable"

Pros: "Service"
Cons: "Food"

Cons: "They boarded everybody at once through a jetbridge made of glad. Very hot in there. You were stopped in a crowded jet bridge in 90 degrees for 25 minutes because they board everybody at once and it took time to get passengers into their seat."

Pros: "Entertainment system very good ; crew very professional"
Cons: "Airline might have given warning of long long distance between connecting gates and need to undergo another security check. Also waiting area very cramped."

Pros: "Great crew!!"

Pros: "The flight attendant was helpful in confirming that my connection gate was C14."
Cons: "I only had 45 minutes between my Washington DC flight and my flight to Frankfurt and the flight to DC was delayed by a few minutes. Because the carry-on baggage had to be checked it took extra time to get my bag after the plane landed and my connecting gate was in terminal C (I arrived at terminal A), so I barely had enough time to get there, even when walking at full speed and not stopping once along the way. This was too short of a time between the two flights."

Pros: "The staff was so prompt and friendly"
Cons: "Cramped leg space, no entertainment"

Pros: "It was a nice, efficient flight"
Cons: "Guy at exchange should have said - All Lufthansa connections this way that way if a gate change had iccurred one didn't have to go thru security again..."

Cons: "This flight had a lactose free meal but not gluten free."

Pros: "Meal service (pasta was excellent), entertainment offerings, enjoyed the small snack bags. Flight not too full allowing for easy access to luggage, and some open seats. Great plane with restrooms in lower fuselage allowing you to walk around and stretch a bit."
Cons: "Leg-room limited, especially in rear window facing (two-seaters) rows 50 and back."

Pros: "Really a nice meal and good service"

Pros: "Seating space is like putting 5 pounds of something g in a two pound bag. Not enough space."

Pros: "Seat 5A was great"

Pros: "The wine"
Cons: "Nothing"

Cons: "Beverages"

Pros: "Boarding was very smooth crew was very pleasant and helpful"

Pros: "Nothing much but the crew made up for some of it."
Cons: "ORD and the roads approaching nothing short of a nightmare. Chicago should be embarrassed by the whole experience at ORD."

Pros: "Everything."
Cons: "Waiting for 30 minutes a Dublin to dock."

Pros: "Went on time and looked after very well"
Cons: "Going over leg room, a bit tight"

Pros: "The staff were very friendly and helpful"
Cons: "Bag checkin had already been done online but did it again in terminal, weigh in lady not helpful or friendly, quite abrupt. Onboard seating cramped and worse when front seats were reclined."

Pros: "Things went very smoothly."
Cons: "Long layover"

Cons: "After being delayed without any explanation, I was told that I would not have my purchased 1st Class seat. To add to that I received no service In economy."

Cons: "For our delay with no information"

Pros: "Movie selection, drinks"
Cons: "Kayak/JustFly charged us a fee to pre-select our seats which was appealing traveling with a baby. However, upon checking in, we found that the seats were not reserved and the fee was a marketing ploy. The airline attempted to separate our family of 3, but luckily it was not a full flight and we were able to sit together with no help from Kayak, JustFly, British Airways, or American. Kayak/JustFly made the experience of traveling overseas with a baby more challenging than it otherwise would have been which is a terrible way to conduct business. We will never be using these services again and will tell family and friends to do the same."

Pros: "I lucked out, I was in a row alone, so got to stretch out and sleep for 3 of the 6.5 hours of the trip."
Cons: "The entertainment might have been good, but the touch screen system was extremely cumbersome andf it was hard to get a good overview about what was available and then when one thought one had chosen something, something else started to play. I tried to listen to classical music, but the cabin music was louder,"

Pros: "Everything was okay and scheduled for me, I just walked into the airline and showed my passport"
Cons: "I would like to get a 24 hour before remainder and chance to pick my sits!"

Pros: "Plane and staff were great. Very easy boarding process and we landed early in Dublin airport after an hour delayed take off. Food and staff service was very good, no complaints."
Cons: "No idea how they messed up the take off and landing times so greatly. left an hour late and arrived an hour early. No personal entertainment screen and plugs were not working."

Pros: "All is well."
Cons: "No worthwhile complaints."

Pros: "Excellent service. Loved the tv screens with the remote. Exclennt flignt"

Pros: "Got to pick my seat. Got food. Spacious. Timely. Friendly. And best of all.. the middle seat was open and I got some extra leg room!"
Cons: "Hey for airplane food I can't complain. Especially since I didn't even know I'd be getting any. (For free!). The chicken and mashed potatoes were a little funky but still ate and enjoyed it."

Cons: "I was told that because my passport would expire in 2 months that I wouldn't be allowed to board the flight. I was never alerted of this in the booking process."

Pros: "After the debacle of ATL > Chicago, this flight was a welcome reprieve from the crazy. Aer Lingus can get my business again."

Cons: "Too tight, seat was uncomfortable, food was bland"

Pros: "Personal TVs with many movie and game options. I also liked that I could view the flight map and timing details. Meals and crew were great too!"

Pros: "The crew was fantastic. Enjoyed the Free movie options."

Pros: "There was a lot to see"
Cons: "The screens were severely delayed and frustrating."

Pros: "In your Chicago office. He was extremely helpful both to us (too older ladies) and to others. Please thank him for us and look at him for a promotion. I think he may work for American Airlines instead of British Airways."

Pros: "Nothing whatsoever"
Cons: "I was confused by the Brot"

Pros: "Prompt and curtious"

Pros: "The food was good and the flight attendants were great."
Cons: "No personal entertainment, just the old TVS every 6-8 rows."

Pros: "Everything was fine except it was inexplicably late!"
Cons: "It was over 30mins late for no reason!"

Pros: "I liked that we got into Dublin earlier than expected. I really liked the amount of legroom-- It's rare for me to be able to sleep and I did. Thank you!"
Cons: "nothing to complain about--"

Pros: "Food and "free" drinkscomfort of seats overall"
Cons: "Comfort of seats in which to sleep"

Pros: "Staff on the plane were nice."
Cons: "5 hour delay, fear of cancellation ruining a trip planned for years, not feeling we were told what was happening, series of delays extending decision time, unappetizing sandwiches during delay."

Pros: "Free alcohol and good passenger friends and friendly service."
Cons: "No outlets for phones"

Pros: "Gave us plenty of food and entertainment"
Cons: "the touchscreen for the inflight entertainment wasn't working properly - slow/unresponsive on the right side - and the announcements were deafening over headphones"

Cons: "Wasn't able to catch up this flight because of the cancellation of the connecting flight."

Pros: "The crew were beyond excellent and tried to help with the seats. They were also very apologetic for the seat issue."
Cons: "Our seats had no power and couldn't adjust. The crew manually did it for us but we never got it to go close to flat. We were on an old 757 which is such an embarrassing product for AA compared to the new or refurbished planes."

Pros: "Seating way too tight"

Cons: "The plane had no TV in front of the seat for a international flight, the space was tiny as well. I could never recommend this to anyone else."

Cons: "a little difficult to check in on line as we booked through Finn Air but was AA operated therefore the many reference codes did not work and had to call agent but got it worked out."

Cons: "When we arrived to Chicago we discovered that the airline had tried to "fix" out connecting flight and in the process I was accidentally removed from the same flight as my husband and we were both forced to take detours through London since we had missed our direct flight. Our checked baggage was lost for 2 days. The London airport has more strict rules for carry-on bags and liquids so much of our items were confiscated and the worst part of all was being told at the gate in Chicago that they didn't know why I was removed from the flight but that I would not be allowed to board because they couldn't reach anyone at the American Airlines desk. We pleaded for help for over an hour and were basically asked to sit down and be ignored. I was sobbing when my husband and I were separated and we were worried we might not find eachother in London or in our final destination of Dublin since we had no cell service."

Pros: "Smallest transatlantic plane ever! Too mich tirbulence for a plane this small on its way to Europe. I was expecting to be on Finnair and was on some crappy American Airline plane that just arrives to NY from Miami. Worst flight ever."

Cons: "The flight attendants were rude, they had no dinner, no healthy breakfast options, they rationed the beverages and after being without enough water for 12 hours, they would give you dirty looks when you asked for a second serving of plain water."

Pros: "Good value"
Cons: "Poor food quality"

Cons: "The food.... But you already know that, don't you."

Pros: "I liked the service, the puntuality and the airplanes they were comfortable. I enjoyed it I hope my return will be the same."
Cons: "nothing."

Pros: "We lost a full day with delays using american airlines /finair when flying to dublin. Their "free" sandwiches to hold us over is embarasssing. We then missed our plane because finair informes us after waiting online we needed to go to another terminal to check bags at american airline. That was not initially told to us and now we are spending over $1000 so we can fly tomorrow plus hotel room. It also affected a business trip to vegas which i needed to cancel. My experience was terrible with finair and american airlines with terrible customer support at the airport. Amazing how we need to pay another 1000 for terrible communication."
Cons: "Lack of communication from airlines Delays Forced to pay a return flight fee plus hotel fee due to finair inabilityty to communicate and direct customers to right terminal."

Pros: "The emergency exit row had decent legroom and I was comped my beer."
Cons: "Perhaps it was my own fault, but I kept getting errors trying to check in online at the Finnair website. I was there because up until I tried to check in at JFK, I was 100% sure I booked a Finnair flight, because that's what Kayak told me. I was pretty pissed off when I found out that SURPRISE I was really flying on American Airlines, pretty much the most boring airline on the planet. When I checked in, I was still unable to get a seat assignment, not until I got to the gate where I had to wait 20 minutes for an agent to show up and sort things out. They finally put me in an emergency exit row, in an extremely uncomfortable non-recline seat (I know, regulations). The flight was also an hour late taking off (I know, not AA's fault), which did not help the experience. Will be more careful next time booking on Kayak."

Pros: "Food, entertainment and free checked bag. Can ask for more!"

Pros: "The crew was spot on with there interacting with us passengers and very good doing there job"
Cons: "Food and drinks lol"

Pros: "Just the crews"
Cons: "I feel the options when the flights didn’t work out could be much better and the managers could be more helpful with finding accommodations. For example my flight was canceled the young lady behind the counter was more helpful than the manager when exploring options to get me on my way to Sudbury in which I had to catch the bus which was fine but to get to that conclusion took forever they provided a ride to the station and thats it"

Pros: "Food and crew excellent."
Cons: "Boarding process delayed as groups 3-6 all lined up together. No air at seats"

Cons: "Power outlet didn’t work in 34G so couldn’t get work done."

Pros: "For the 9 hour flight it would have been nice to have a screen with movies available."

Pros: "Everything"
Cons: "Nothing"

Pros: "Crew were nice, food on board was ok Given the long wait time at immigration, we did not have to wait for our bags."
Cons: "Rouge seats are notoriously uncomfortable, especially on a 9 hour flight. Rouge Player entertainment sucks, very poor movie selection. Irish immigration took 45 minutes... a ridiculous amount of time in this day and age. My time with the officer took about 30 seconds, so obviously the problem is that they are understaffed...not the best way to start your trip to Ireland after a long flight!"

Pros: "Good service, surprisingly good food, smooth and efficient."
Cons: "The premium seating we paid extra for because we need leg room (my partner and I are 6'+) was the first row behind the 1st class seperation wall...so no way to extend legs by placing feet under the seat in front. Not very comfortable or worth $100 IMO."

Pros: "The 1.5 hours they turned the lights down and stopped the crew from going constantly up and down the aisle."
Cons: "We were traveling from 11 pm local time to 10:30 am local. However they kept all the lights on for nearly the whole flight. In addition, the crew was constantly going up and down the aisle with food or beverages. It made sleep impossible. To make matters worse I’m allergic to dairy and I tried to prebook an appropriate meal but couldn’t and everything had cheese."

Pros: "Customer service crew sorting us out on new flights had patience of saints"
Cons: "Did not make flight, gate crew rude and did not give information."

Pros: "Very little I'm afraid."
Cons: "A lot ohe seats are faulty the entertainment system barely works, mine didn't and even if it did the headphone jack was broken! The cabin is more than grubby, it is dirty with torn fabric and faded writing on dirty plastic. I skipped the meal on the return flights as the outbound were the worst I have ever had! In all honesty I'm not a fussy traveller and never write reviews but Air Canada was so bad I thought it might be useful info for someone."

Pros: "The plain was not full and my section at the back was quite empty so I had seats to my self and was able to lay down. The plane had been recently refurbished and everything was clean and new."
Cons: "Very rushed boarding, this happened last time too. They called for my section to board and I immediately got into line. They made two more call where the staff sounded quite annoyed. "We're still missing passengers" " If you are in section 3 you need to come to the gate right away" he made the second call when there was one person infront of me in the line. Like everyone was in line we just hadn't been processed yet. I don't know why we need to be rushed onto the plane by impatient staff. My entertainment device stopped working in the middle of a movie and didn't work for the rest of the flight."

Pros: "The flights were great, on time and no problems. I was very comfortable and the food was good. FLight attendents were great except one guy who was not friendly and needed a vacation or another job."

Pros: "Easy flight to Dublin."
Cons: "Boarding could be better organized - staff should make sur only the people in the zones called are in line. Not everyone from all zones. The zones 3-5 line isn't helpful. They should change it to "boarding" and indicate only thsoe called to board should be there. Otherwise, they need separate lines for EACH Zone."

Pros: "on time"

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

Pros: "The staff"
Cons: "No TV monitors and food was bad"

Pros: "Great great great staff on the flight. Fast direct service ... Landing in T1 Dublin really speeds things . Checkin in good until.... See below"
Cons: "Plane was late leaving. Food was served around 2-2:30 am. Realize this budget but still 750$... Movies - player kept stalling Check in ... Crazy on bag drop at check in #5 lane in departures in Toronto. Perhaps one more staff at high volume to make sure the folk in the bag drop line actually have bag tags. Travel to same route last year at this time and it was the same experience."

Cons: "Was surprised not to have screens in the seats to watch movies on an international flight."

Pros: "At fisrt the flight was over booked. Once we had boarded their was a technical issues with the aircraft, we had to sit in our aiys with nothing to do for just under 2 hours. With this delay in mind their was no form of a free drink as a mini compensation. They had no choice of food."

Pros: "It is convenient to take Air Canada from our town and connct in Toronto."
Cons: "The staff are barely polite and do not really care about the passengers. No smiles, Not friendly or welcoming. We trwveled in US last month.. What a difference in attitude. The food was awful, bordering in inedible. (example salad was cold canned corn with shreds of cabbage and no dressing.) Breqkfast was a piece of bread with choice of orange or tomato juice. No tea or coffee. They lost one of our bags, no apology and another company handled the search and return. No reason given to leave it behind. baggage and carry on rules are complex and complicated, and you never know when they will decide to enforce them and penalize you. If you can get there any other way don't go Air Canada."

Pros: "We were served three meals (two full meals and a snack) and free entertainment in individual seat TVs. Cheapest flight from DC to Seoul."
Cons: "Arriving Toronto customs and immigration was so unorganized and frustrating."

Pros: "Friendly crew. Boarding was very chaotic and our seats were originally booked together and someone needed up separate. In the end, the crew worked it out for us and we were satisfied."
Cons: "I've flown this airline a few times and the seats are pretty uncomfortable."

Pros: "The crew was so good and friendly. I had an overnight flight and so having a considerate crew is so important. The comfortability was decent for being a plane and long distance."
Cons: "It was a 6.5 hour flight and there was no entertainment. Every additional amenty cost extra."

Pros: "Food was ok"
Cons: "Avoidable delays caused a late departure from Toronto, then we sat on tarmac waiting for a gate in Dublin. Eventually had to debark into the tarmac and walk in. Delays caused us to miss our next flight to Munich."

Pros: "I liked the streaming entertainment I enjoyed the friendliness of the crew I was pleased with the Canada air app allowing check-in and tracking of flight"
Cons: "The comfortability of the flight was poor. Both my wife and I were too uncomfortable to be able to sleep on out more than 9 hour flight. Leg room bad, seats uncomfortable."

Cons: "LGA Gate #6 and #7 to cold, people were freezing. Also, those two gates are like cattle barn."

Pros: "I liked that the flight was not completely full. we had a hard touchdown"
Cons: "1. These days, I have come to expect a complimentary in-flight entertainment system on international flights. This flight had nothing whatsoever. This is ok, but the customer should be warned when making the flight reservation so they can choose whether to bring an ipad along. 2. Food and service were not as good as a recent Air Canada return trip from Roma to Vancouver which had a first rate crew, food, and complimentary beer. 3. The plane was much older than the recent return trip I had and the air was much more dry."

Pros: "The only thing I liked about my flight to Dublin was the fact that we arrived in the correct city."
Cons: "Once again I found the air Canada staff unaccommodating, un-attentive and basically indifferent to the aircraft's guest. In addition I tried 4 electrical outlets on the aircraft before finding one that worked and the reading lights never did work. I would never recommend this airline."

Pros: "The plane was newer and clean."
Cons: "For the price I would have expected a little more. The food wasn't good it was just mac n cheese with bread."

Pros: "Safe and efficient."
Cons: "Poor seat room. Food quality mediocre."

Pros: "Crew very polite and professional."
Cons: "My luggage didn't arrive at destination, so this caused a bit of a problem for me as Philadelphia was not my final destination. I had to take a bus the next morning at 7AM to Pittsburgh. My luggage finally was delivered to me within 48 hours, so that was great."

Pros: "Great seat-back system, very good food and friendly, helpful service both in the air and on the ground. Very nice to let families board fairly early."
Cons: "Entertainment choices could have been a bit better. Would have preferred to be able to get seats more than 24 hours in advance as a group of 4 (without paying exra). I think we got the last 4 seats together."

Cons: "The fact there was no entertainment system available for a 6hr international flight is a crime. Apparently there is some sort of app you need to download on a mobile device or computer BEFORE the flight, Would have made a huge difference knowing that."

Cons: "There were no screens to watch anything on for a flight across the Atlantic. And we were told once we boarded that we needed to download the aircanada app in order to get content. Well by that time I didn't have free wifi and couldn't download the app. Very frustrating. I would suggest announcing this before people board the flight."

Pros: "Got to spread out onto two seats since flight was not crowded."
Cons: "Food options. No inflight seat with entertainment screen."

Cons: "I am 5' tall and there was no leg room for me."

Pros: "Great flight crew, fairly comfortable seats. Made a 10-hour flight pretty bearable."

Pros: "Boarding was smooth and the crew was wonderful!"
Cons: "Air Canada changed my seat assignment at the gate. I had chosen a window-seat, but they switched me to a center seat. Also, there is no free in-flight entertainment if you don't have your own tablet/smartphone (neither of which I have). You can rent i-pads. I wish I had known that before flying."

Pros: "Great crew. Gracious and helpful."
Cons: "Kayak was a nightmare to work with."

Cons: "The fight itself was fine. Not great. Not terrible. But the airline lost my son's suitcase and has been entirely unhelpful ever since then. Now we have been stuck in a foreign country without clothes and toiletries for 36 hours and Air Canada's "helpline" has been anything but helpful. They can not find any information on the location of the suitcase and hope that they will find it in another 48 hours. Rediculous!! I will never fly them again and suggest that you save your money, effort and vacation by flying with another airline."

Pros: "The flight crew were nice and friendly, though they weren't very on top of trash pickup, but they were chipper and that's always better than grumpy crew that are super-efficient. Also, our luggage made it with us despite a tight connection."
Cons: "53 minute hold time to call center (before my call was even answered) to order vegetarian meals for flight (the day before flight) -wish that could be done online, vegetarian meal request not transferred to new flight after we missed our initial flight due to first flight delay, lights not working properly for half of flight (sleeping child under spotlight), the pasta dish, collecting garbage in my seat throughout flight (particularly after meal service), cramped seating, lack of entertainment, and they are now charging for alcoholic beverages on international flights. I'm not a big drinker, but I still enjoyed that perk."

Cons: "Had to use your own electronic device. Did not know that you had too download an app prior to boarding. No personal control over cooling/heating. Never fly Air Canada Rouge in the future"

Pros: "Toronto is a lovely airport, and it's a short hop to Europe from there, which is why Air Canada Rouge is ok for the trip. It's important to remember that their no frills approach means no TVs. Sleep or plan accordingly."

Pros: "Again the crew was enjoyable and the timliness of the flight and the boarding process was great. Also I appreciated the blanket and pillow given for the flight"
Cons: "There was no entertainment for this 6.5 hour flight, I was very disappointed with that."

Pros: "Flight crew was nice"
Cons: "Where do I start. Plane was very late taking off but the biggest thing was that I paid extra for a premium seat and I think it was worse then any regular seat. Waste of money!! Now the food. It sucked and there wasn't much of it. Dinner was at best skimpy and " breakfast" was a piece of some kind of cake. That was it!"

Pros: "Food tasted good"
Cons: "How close together the seats were."

Pros: "That we made it there reasonably on time."
Cons: "Old plane, no entertainment unless you knew to get their app, before getting on the plane, limited leg room, bad food, no drinks on an int'l flight. Too bad it was the same price others charge."

Pros: "Smooth boarding, friendly crew, pillow and blanket both serviceable. Food was a little better than I expected for economy."
Cons: "Baggage handling ripped handle clean off new suitcase, both ends. Delays in departures from Dublin led to us using stairs off of plane on tarmac. Entertainment mostly dependent on app you can't download on plane if you're using wi-fi."

Pros: "Air staff were somewhat pleasant."
Cons: "Plane (767-300) is so old you have to use their app on your own device to watch movies. Plane is so long it takes forever for even simple beverage service to get to you, blocking aisles for hours while various carts are dragged about. Servings were mean, you could only get the can of soda if you begged, refills were also slim, and ice was a cube, maybe two. At one point I was so dry I had to page air staff to ask for more water (and I Never do that!). Food was mediocre at best. Landing, plane shook so hard I thought it would come apart! Planes like this need to be retired FAST. Last time I will fly this equipment. I'm literally going to pay all those ridiculous fees to change my return flight. Hated this exhausting, inconvenient, unpleasant and entirely too expensive experience. Don't fly Air Canada overseas!!"

Pros: "Good crew"
Cons: "No wifi"

Pros: "Great experience!"

Pros: "Flight crew was top notch"

Cons: "The boarding procédure in Dublin requires à long walks in 3 différent locations. Should be ma de shorter"

Cons: "The WiFi did not work the entire flight (4 hours from Chicago to Seattle) and despite passengers inquiring multiple times, we were never informed whether to expect it to start working or not. Streaming TV was also poor quality on the United app."

Pros: "CRES was great"
Cons: "Many of us waited about 40 minute for our bags to show up in the reclaim area."

Pros: "The crew was friendly and helpful."
Cons: "I have no complaints!"

Cons: "Seats were a little uncomfortable but overall not bad."

Pros: "Crew amazing, smooth flight and on-time"
Cons: "Legroom and the fact that there is even s lower version of economy now! Yikes"

Pros: "On time departure & arrival"

Pros: "I didn’t die in a plane crash."
Cons: "They missed the connecting flight the day before, so we had to fly out the next day on a flight that left ~1 hour late. I know the staff is doing what they can so I blame the execs making millions because they’re typically the real problem anyway."

Pros: "The crew was awesome! Best flight I've ever had."

Pros: "Big windows"
Cons: "Too cold during red eye"

Pros: "Nothing"
Cons: "My economy plus seat wouldn’t recline!"

Cons: "We didn't fly here"

Pros: "They did allow myself and children to board earlier 5/4."

Cons: "I wasn’t able to take the flight due to illness. Called Just Fly and airline for help - was on hold for hours. Both refused to help me. I am now out of pocket over $700. Appalling customer service by both airline and agent. Planning to report to the Better Business Bureau and travel authorities."

Pros: "Nothing"
Cons: "Landed in Canada to let off a "sick" passenger, sat there for hours and after the pilot made countless excuses, including needing to refuel, needing a new route, and needing to de-ice the plane, he finally announced that we're headed all the way back to Newark for some unknown reason. Worst flight ever. Couldn't be any less happy. F*** this airline. Will never use again. Ruined my vacation, thanks a lot."

Pros: "Crew members were pleasant"
Cons: "Gate was changed to a gate much farther away. Flight was delayed for 4 different reasons all of which were unlikely. We left 4 hours late. On board the plane was freezing cold. I will NEVER fly United Airlines again."

Pros: "Legitimately, nothing was liked."
Cons: "My plane broke, worked multiple mechanicals, returned to the gate, my severely delayed departure caused all my connections to be missed thus creating more compounded issues. HUGE HUGE headache. Almost forgot, I'm still missing my luggage 2 whole days later."

Pros: "The space on the plane, we left on timeand arrived early and I was able to sit by myself."
Cons: "One of the stewardesses spoke very harshly to me. I felt very embarrassed and offended."

Pros: "At least UA rebooked me next day no charge."
Cons: "Had to cancel trip until next day due to initial flight so delayed I would have missed connection in Denver. Since UA claimed was weather related, I woulda been responsible for hotel."

Pros: "they gave a $100 voucher"

Cons: "The delay!!!"

Pros: "Arriving in Dublin"
Cons: "Seat was cramped and uncomfortable"

Pros: "An empty seat in the middle."
Cons: "The seat in front of me reclined further than all the rest and the new seats that United has installed are incredibly uncomfortBle especially for a long international flight!!"

Pros: "Nothing"
Cons: "Over 4 hours of delays including on plane then everyone was kicked off. We waited more and they cancelled the whole flight and everyone had to scramble to get on anything available. I lost 28 hours of my vacation. They put us in a scary hotel in Chicago. I received a $200 voucher for further flights that doesn't even cover the cost of my unrefundable expenses such as car, hotel and tickets that were lost on my vacation."

Pros: "Entertainment was good"
Cons: "Flight delayed for 2.5 hours. Food at airport terminal specific to United ridiculously expensive, particularly for a family, e.g.. $8.50 for French fries, etc."

Pros: "We made it to Dublin..."
Cons: "Crew was terrible, grumpy and not welcoming. Boarding was terrible, 4 hours late. No compensation, little apology. Food was awful. Couldn't really tell what we were actually eating. Actually hated this flight."

Pros: "I loved the butternut squash pasta. I plan on making this recipe at home. The staff was also very pleasant and accommodating."
Cons: "My seat was uncomfortable and the person in front of me kept reclining. I had very little space to try and make myself comfortable. I am 110lbs, so I can't imagine how a larger person would feel."

Cons: "For an international flight, there should be more amenities like charger etc."

Pros: "Crew was very attentive"

Pros: "Polite and friendly staff."

Pros: "I overslept my flight and United was able to find the next available flight into Denver which helped me tremendously. The guy on the phone was very pleasant and helped so much."
Cons: "Boarding was disorganized and hard to understand. Flight was delayed because of paperwork that wasn't signed, which caused me to miss my connecting flight."

Pros: "There is no food essentially. No entertainment unless you have your own electronic hand-held device."
Cons: "See above."

Cons: "It was freezing on the plane."

Cons: "Seats are too close."

Pros: "The Embraer ERJ-170 has comfortable seats!"

Pros: "Flight crew in Dulles were very helpful in arranging for my daughter and I to sit together. Really appreciated their help."

Cons: "More leg room"

Cons: "There was a delay with the flight. I wish there had been earlier communication about what was going on, i.e. Why it was delayed, how long will the delay be."

Pros: "The seats were comfortable and spacious place were awesome :) The snack was very good, the best I had so far while flying. Service was great :)"
Cons: "I didn't like that because I was 4th group to get in the plane, all the space above my seat was full and I had to go put my carry-on quite further down. It didn't cause me any problem because my connection flight had a long layover, but if had not been, I could have been late."

Pros: "Two meals, great staff, eventless flight"
Cons: "2+ Hour delay due to airplane issues limited space under isle seats for carry on bags"

Pros: "I was very nervous, but the flight attendant made me feel at ease."

Pros: "On time!"
Cons: "Old plane- lots of noises/raddles. Flight attendant not especially friendly, but that's ok? Wish United went direct from Louisville to Ft Myers. Need to add trip to Frequent Flyer Account"

Pros: "We were tossed into the last row; I had no leg room and was constantly being bumped by people using the rest rooms. As a result it was a sleepless flight."

Pros: "After being in the air for 4 hours without being able to connect to listen to anything, a gentleman flight attendant came to ask if I needed help. He then tried a couple different tools to try to help me. Nothing ended up working, but I appreciated him trying."
Cons: "Before the flight took off, I mentioned to a female flight attendant that there seemed to be something in the headphone jack and would like some assistance. She said that it wasn't the time to assist me with that (which I can understand), but she never came back to try to help. Once in the air, another women recognized that I couldn't connect and said she would be back. I am not sure if she forgot or if sent the gentleman flight attendant to assist, I felt like I wasn't heard at all."

Cons: "For a trans-Atlantic flight this was a very small plane with very tight seats. The bathrooms smelled throughout the plane. Many seat back TVs didrn't function."

Pros: "Great boarding at ORD."
Cons: "My seat"

Pros: "Nothing"
Cons: "PA unreadable, entertainment screen broken, special allergy safe meal lost, luggage didn't transfer to next plane and we actually had to drive back to airport and get it 25 hours later loosing time on our trip,staff apathetic to everything! Will NEVER fly United again!"
