Pros: "Crew was excellent, seats are never excellent"

Pros: "Good"

Pros: "I think Delta is upping its game, and I’m pleased to see that. Almonds for snacks, phone info about the state of your checked bags—good stuff."
Cons: "Of course the seat was not “super comfortable,” but whe you pick Economy, you know that."

Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."

Pros: "Quick flight...ahead of schedule"
Cons: "Cheese It’s are boring...miss the snack mix"

Cons: "Delays were unfortunate, but the gate area at LaGuardia was way too crammed, hardly any seats, and poorly organized"

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."

Pros: "Nothing spectacular."
Cons: "The headrests won’t stay up. And it’s hot."

Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."

Pros: "Staff from Check in to aircraft very pleasant. Snack choice in Coach impressive."

Pros: "Good snacks"
Cons: "Nothing"

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."

Pros: "Check in Denver super helpful Gate staff hustled to turn around flight Flight crew excellent"
Cons: "Flight delayed, almost missed international connections"

Pros: "Boarding, friendliness of staff"

Pros: "Everything was easy and smooth."

Cons: "The baggage drop attendant was very unhelpful when I asked if she could help me sort out an issue (when I checked in online for the second leg of my trip, i paid for my bag then but they wanted me to pay again for my first flight) and just dismissed me and said she couldn't help, making me pay again for my bag. First time I've ever had an unpleasant experience with Delta."

Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "The fact that there was a screen for movie selections and a charging port for my phone and the flight attendants were super nice"

Pros: "Good flight crew"
Cons: "Delayed due to mechanical issues. For 3 hours. No offers for free drink or wi fi. When we finally land we were on the runway for half hour."

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Cons: "Z"

Cons: "was a difficult transition from delta to west jet in Toronto and we almost missed the flight"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."

Pros: "On time as scheduled."
Cons: "N/A"

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Boarding super excellent! Also: Best landing I've ever experienced! Props to the pilot!!"

Pros: "Overall the actual flight was good..landing was kind of hard but I'm alive so not stressing that"
Cons: "..but the multiple delays are ridiculous, I would not fly Delta if I had a feasible choice."

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Cons: "No space in the seats"

Pros: "Great,I loved it!"

Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."

Pros: "The moviea"
Cons: "The time of night"

Pros: "Crew"
Cons: "3 hours there before the departure."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "First we had a mechanical after boarding. I was rerouted through Atlanta. That flight is now delayed by 2hours. I then had to reroute to West Palm Beach instead of Ft Lauderdale. I will leave 9 hours after my original flight time and arrive 8 hours later. Just ridiculous"
Cons: "See above"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Cons: "I was not expecting to get on a full 8 hour flight with no meal unless I pay for it. Although the mistake on purchasing a flight without meal may come from my end, this logic of having to pay for a meal is not ideal whatsoever, this should never happen, especially when going on a 8 hour flight, meals should always be included regardless! never heard of this ever in my life of using westjet for 7 years , very disappointed."

Cons: "Explain the reason of the delay to us. Service while boarding was very poor No smile or welcome"

Pros: "The movies"
Cons: "So far so good"

Cons: "Booked our seats 24 hours in advance and could not get seats together. Airline expects us to pay extra for reasonable expectations as that"

Cons: "Tiny chairs"

Pros: "Talia is an excellent stewardess—She takes good care of people"

Cons: "The plugs don't actually charge anything... :-/"

Pros: "Haven't taken it yet"
Cons: "Well I'm not on the plane yet cause you left.me stuck in Vancouver"

Cons: "Boarding process complicated, bad smells in cabin"

Pros: "They were quick and efficient"

Pros: "Smooth flight"
Cons: "Wheel chair services was horrible. 8 passengers needed assistance and there were 2 assistants to aid them. This took over two hours as they attended to passengers with connecting flights first. It was frustrating waiting 2hrs after the flight landed to collect luggage and leave airport."

Cons: "Woman in seat beside should have taken 2 seats"

Pros: "No issues"

Pros: "Quick boarding and quick to disembark."
Cons: "tiny! you get what you pay for with a turbo prop."

Pros: "Great experience...."

Pros: "No movies, not sure whether I needed to Dow load something Did not have food"

Pros: "Nice"

Cons: "There were so many delays"

Cons: "To the best of my knowledge I paid for a window seat on my trip to Montreal. It was the only option I elected to pay for, yet, I found myself in the middle seat. A personal life lesson we’ll learned and an experience to be remembered & considered, under advisement, on any future bookings."

Cons: "Small!!!"

Pros: "The people that work for WestJet are exceptional! I find everyone there is knowledge, helpful and happy. The last one is why I fly with WestJet. Its a real treat to be so well taken care of."

Cons: "it was very good"

Pros: "Service up to standards"

Cons: "Delays on boarding"

Pros: "Nothing. Lame service."
Cons: "Delays and no compensations"

Pros: "Entertaonment did not exist....did not even have a sandwich...just junk food"

Pros: "It was really hard to hear the boarding announcement as I was very close to the gate."

Pros: "Crew was amazing, seats were comfortable. Only negative is out of your control - bad weather in DFW held up departure 5-6 hours. Much of that was on the plane, but crew kept us notified. We had to return to the gate and wait another couple of hours. Awful trip, but not your fault. What I was surprised by was no comp hotel, and the discounts were not rally good discounts."
Cons: "Most of my issues were ATC problems, not AA. The AA personnel kept us informed, etc. The one thing you can control is hotels if delayed to the point of missing all connection until the next afternoon. I understand not compi9ng BUT, when google maps shows better rates at local hotels than your "discount" program, that's sad."

Pros: "Great crew"
Cons: "Snacks"

Pros: "Not much"
Cons: "The customer service, both on the phone & in person"

Pros: "Flying portion was fine."
Cons: "Flight delayed for mechanical issues.... then upon landing trapped in cabin filled with exhaust then again trapped in a locked hallway."

Cons: "Find a sooner alternate flight"

Cons: "If we had access to the WiFi to watch shows earlier like United does, that would be nice."

Pros: "comfortable plane."
Cons: "Kay&k was awful. Never use them again."

Pros: "Honestly, nothing!!"
Cons: "Everything. This airline has disappointed me for the last time."

Pros: "It was average."

Cons: "Seats are too close"

Cons: "Old aircraft ...what’s with the non-assignment of seats until the last minute unless you pay extra !"

Pros: "Entertainment available excellent"
Cons: "Seating space seems to narrow"

Pros: "liked the crew, but didn't know that we would have to check our bags, since the plane was small & had no overhead. Also, I wish I would have been told ahead of time, that I would have to check my bag again going home, even though the plane did have overhead space. Other than that, I love AA!"
Cons: "I didn't get very good instructions about picking up my carry on bag plane side. I was told to go to the baggage claim instead by a staff member when I came out of the plane, but this was wrong, so I ended up waiting a very long time for them to bring me my carry on bag to the baggage claim."

Pros: "didn't get my flight you said booking was guaranteed refund 24 hours but when i call to change or refund you said the airline would not change or refund. you didn't live up to your end. if you refund i would consider tat but for now. i would never use kayak again and will post my experience"
Cons: "you could have change my return when i called 2 hours after or 18 hours after now i have to pay 500 to get home you should live up to your rules and refund my money"

Cons: "When I checked in on line, I was asked to choose my seat. However, there were no seats available that were free of added charge. I had to pay another $50.00 for a seat. I do believe, when I have a confirmed ticket, I should not have to pay an additional charge for a seat."

Pros: "Service for wheelchair was excellent with staff at checking counters"

Pros: "We were early but couldn't get to the gate!"
Cons: "Same as above"

Pros: "The flight attendant"
Cons: "Service was poor."

Pros: "Price, entertainment, direct flight"
Cons: "Plane left because pilot was late, little to no legroom for a 6"2 person. Boarding procedure is a joke. Instead of their group system the plane should be boarded from the back. By the time group 8 comes on board there is no room in the overhead bins."

Pros: "Prompt on time service."
Cons: "N/A"

Pros: "Seats which we selected where great"
Cons: "I would have like the opportunity of moving up to preferred seating. Would be willing to purchase it"

Cons: "They changed my flight schedule that made me have to arrange my travel plan"

Pros: "Nothing"
Cons: "Someone stole an ipad and that forced us the be delayed for 2 hours"

Pros: "My flight was delayed many hours so I wasn’t going to make my connecting flight in NY it to Toronto, There service agent was great and found me a seat on a later flight that was direct. Overall, happy with their service found me the best flight available."
Cons: "I never could figure out why the flight was delayed, there were a couple of other delayed AA flights too. I was supposed to get to Toronto at 2pm for a 5pm presentation, but I didn’t get in until 9. I also felt their website was deceptive or maybe needs updating,When I bought my ticket It stated that I would get 3 bags complimentary since it was Canada that wasn’t the case, I was charged for $60 for both."

Pros: "British Airways got us on another flight to Dublin through Heathrow."
Cons: "Plane was late missed the connecting flight. Aer Lingus/American Airlines refused to help us find another flight to Dublin. I called Vagama customer service and the attended refused to help get an additional flight or confirm our returning flight would be held."

Pros: "On time"
Cons: "Small seats"

Cons: "No personal TV’s and no food for purchase"

Pros: "Arrived early"
Cons: "American airlines lost my bag... Customer service in LAX is non-existent."

Pros: "Lucked out with extra legroom seat. Seat was broken though."
Cons: "The whole customs process is a seemingly endless mess."

Cons: "The cleaniless of the flight can get better"

Pros: "Flying AA. Excellent flight"
Cons: "No wifi. Pay only"

Pros: "Besides the seating problems everything else went smoothly"
Cons: "I was not able to get seats assigned to us before arriving at the gate. We got put on the very last row by no choice of our own. The seats are not designed for the average adult, possibly the worst ergonomics of any seats I've ever encountered. Extremely uncomfortable flight."

Pros: "Nice airline very accommodating. Loved first class"

Cons: "My daughter is in a wheelchair. She was a carry on (I e I carry her on board). The staff knew this but failed to notify the airport. Hence, we had to deplane without a jetway. I didn’t. The steep stairs made it unsafe. Had to wait a long time for a handcranked lift. No one really knew what they were doing and they wanted to put her in an adult wheelchair in spite of my identifying safety issues. My daughter was scared and upset. Epic failure on AA’s part. Communication breakdown on many levels. Shameful."

Pros: "Great Wifi! After reading bad reviews it was actually ok. Flew business on the A319 (single aisle plane) and it reminded me of qantas 737. I think for a short haul day flight I may just put up with economy instead for the price. Food is ok. I think with AA you have to pick your aircraft, it makes a difference what plane you fly as to what you get in business class. FA's were great. Overall I'd fly them again. Food was ok."
Cons: "They asked everyone to put the window shades down but I fly window seat because I like looking out! It was a day flight too! LAX T4 lounge is being refurbished so you need to go to T5 and make sure it's not the regional lounge!"

Pros: "Smooth flight"
Cons: "Being delayed"

Cons: "Too many delays"

Pros: "the choice of movies was great. I two very well presented selections."
Cons: "Outside of one drink service we never saw or heard from the crew. Not one food item for purchase was ever offered. I am glad I ate in the terminal or it would have been bad for me."

Cons: "The service had much to be desired. The stewardess who was serving our section was curt and rude. Whenever I would ask for a napkin (that she had forgotten to give with my drink, I might add) or any other questions, she would come off as annoyed and as if I was testing her patience, which I did not appreciate as I had been having a horrible experience with American Airlines as it was. Also, why do you not serve milk with your coffee? The flight only served half and half, and I cannot have cream in my coffee at all. So unless you want to clean up my diarrhea in your toilets, I suggest you start giving options. It's not like milk is a scarce delicacy in the US. How is it that other airlines offer both milk and cream, but I get told by your staff, rudely, that half and half "is milk" and that it's all you have? Unbelievable. I hate to be a b*** but honestly this isn't the first time that I got treated like this on AA. I always seem to have a horrible experience with this airline."

Pros: "not much"
Cons: "not much"

Cons: "This was my first time flying First Class. Not only was my flight delayed but everything was changed last minute. My seats, layovers, EVERYTHING! I was better off paying for a regular seat. I'm a young African American and the stay treated me as if I didn't belong in First Class! Not to mention the last time I flew into LAX American Airline lost my luggage! I have proof to show! Absolutely ridiculous!"

Pros: "They crew tried their hardest"
Cons: "There was no one at the gate to deplane us in Toronto. There for I missed my westjet connection home by 5 minutes. I was looking at the plane by the jet way unable to get on. AA staff would not pay for a hotel for being so late to Toronto because the wether was not thier fault, which I agree. But the lack of staffing was and a hotel should have been provided to me due to this. I will never fly America Airlines again due to my incoming flight to Toronto and the out bound to Philadelphia (cancelled on the way to Philly for no apparent reason)."

Pros: "Renovated planes, modern entertainment options that were free, charging by outlets."
Cons: "Overbooked flight, poor resource management, nickel & diming for snacks on a 5hr flight, lounge access (not Priority Pass, charge $60 for a single visit), no room for onboard luggage, safety video fluff"

Pros: "Had a airline steward named Scott that was very pleasant and nice all throughout the flight."
Cons: "The plane was late/delayed going from Dallas to Colorado and the plane going from Colorado back to Dallas was late/delayed as well ."

Pros: "The crew was attentive and boarding went smoothly. The seat had more room under the seat in front of me, my purse was not jammed in."
Cons: "I hate paying extra for almost every seat on the plane. It's a con job. Food selection was terrible. If I'm paying anyway, give me better choices. No monitors in plane at all. Entertainment needs to be viewed on a tablet or laptop of some sort."

Pros: "everything went smooth"

Pros: "no change in take off was a good relief. crew was great and all smiles"
Cons: "."

Pros: "That the pilot got us home safely."
Cons: "Honestly I am not a big fan of AA. I made a mistake booking my flight but couldn't change it because it was going to cost an arm and a leg. The staff are rude and don't try to help you. It's just a job for them to get by and it shows. Many including myself isn't big fans of AA. I wish this airline gets bought out by Southwest who understands value and elite customer service. They don't charge every little thing like American. I hope soon they can fly into Colorado Springs."

Pros: "Well, there wasn't any entertainment, but that's ok. The flight attendants were nice, and the flight was on time."
Cons: "No complaints here!"

Cons: "Flight was delayed and then cancel altogether. No vouchers provided for the inconveniences."

Cons: "All was as good as expected"

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

Pros: "The seat was fine for economy"
Cons: "You should offer free wifi! Air Canada should lead the way and be above the rest!"

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

Pros: "Crew was great!"

Pros: "Nice seats fast boarding"
Cons: "Snack can be more richer"

Pros: "on time, comfortable (business class"

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: "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: "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: "waiting so long for baggage"

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."

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."

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?!"

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."

Cons: "No wifi"

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."

Cons: "Uncomfortable seats"

Cons: "No monitoring of travel route"

Pros: "I thought that things ran very smooth and efficientlt"

Cons: "I didn't like that I did not get home on the original day specified. I didn't like that my luggage was lost because you all directed me to another airline to get home. It was very stressful and exhausting."

Cons: "The 3hr delay. Not many announcements. No one at the gate/desk. Had to be in a crowded gate area with no choice."

Pros: "friendly prompt service, comfortable seats - free tv and movies"
Cons: "had to circle for about an hour before we were able to land due to a storm but that wasn't the crews fault - just bad luck"

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: "Short movie list"

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

Pros: "Glad for this new route. Will make Europe easier to access from PDX."

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."

Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."

Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"

Pros: "Everything was well organized and we were able to depart sooner than scheduled."
Cons: "There were some items on the menu that were not actually available."

Pros: "There was nothing I liked. The plane was an hour late and nearly missed my connection."

Cons: "Flight delayed"

Cons: "My son was flying on United from Colorado Springs to Denver, then on to Seattle for Thanksgiving. He rushed through as quickly as he could, but the door to the place was closing and it left 10 minutes early. United recorded him as a 'No Show', and there policy now is to cancel the entire ticket is you miss any segment of a round trip ticket. Thus, his entire $900 was forfeited, he couldn't even pay a change fee to catch a later flight. I hate American, and now I hate United just as much. These airlines shills have been allowed to go out of business when they last filled for bankruptcy. We fly in quite a few international airlines, and outside of Alaska, Jet Blue and Delta, maybe Southwest, US carriers are absolutely bottom of the barrel and it's clear that their employees don't care whatsoever. Will never book again in United or American. I'll try Amtrak before either of those carriers."

Pros: "The agent at the gate quickly realized the problem and was able to put me an exit row, which was a nice consolation, but if the flight had been full, I don’t know what would have happened."
Cons: "I was bumped from my first class seat with very little explanation why, and wasn’t even informed until the boarding process was underway. My name was never called at the gate before boarding as a “Mr Smith, please come to the gate”, and it was very embarrassing to be pulled out of line like that."

Pros: "The customer service wait is extremely long especially when u get hung up on and start all over . But one man was very helpful in changing to accommodate me next day"

Pros: "It’s ok. The airplane is not comfortable. It’s old and small"
Cons: "N/a"

Pros: "Landing safely"
Cons: "Late departure. Poor food sale selection"

Pros: "Excellent stewardess. On time."

Pros: "The flight captain made up the total time that the flight was delayed, good take off & good landing, got us to Toronto on time. Thanks."
Cons: "Male flight crew could be better - first do your job of giving out the immigration forms then chat, not complete handing them out just one minute before landing so passengers can de-plane & then fill out the forms"

Cons: "The flight leaving Houston was delayed by over an hour due to some problems finding another captain for the flight thus extending the layover time by at least four hours. As a result I didn't get back to Toronto until around 12:30 in the morning. Otherwise everything else was fine."

Cons: "Wouldnt refund my ticket or change my flight when I needed to change it fee for everything"

Cons: "US Gov shutdown a pain to get thru customs and security. cabin crew on flight to YYZ was terrible."

Pros: "Staff always amazing."
Cons: "No Wi-Fi available."

Pros: "Was good and all went well."

Pros: "I like the entertainment screen"
Cons: "The mini pretzel.,,"

Pros: "Colorado Springs is one of my favorite airports. It is well run and maintned, friendly and efficient"
Cons: "The seat in the exit row was uncomfortable"

Pros: "Nothing."
Cons: "Delayed flights leading to incredibly tight connection times, staff inconsistent with messaging re the source of the delay, zero compassion for customers, offering $700-$1,400 to get off the plane when you charge $200 to change a flight 2 weeks in advance is especially galling! Will not fly with United again whenever there is a viable alternative to my destination."

Pros: "Great service! Smooth flight!"

Pros: "I really like how your flights are inexpensive compared to others when trying to purchase a last minute ticket."
Cons: "The last two times I traveled ( I flew with United Airlines ) and both times my flights were delayed. The first time it was delayed by 4 hours and made me miss an appointment. The second time it was delayed by over 13 hours. It was nice that United had put me in a hotel room for the night, but again it took away from time in which I needed to be somewhere else."

Pros: "Everything was great and i hate flying"

Pros: "Cannot rate the food as I didn’t have any."

Pros: "Good flight"
Cons: "Why can’t the plane be boarded from the back to the front. Seems like that would be easier for all passengers. Also, I picked assigned seats when I purchased the tickets and my husband and I where separated in different rows."

Pros: "Quick boarding"
Cons: "Pretzels are not good snacks"

Pros: "Roomy sears free WiFi. Free coffee"
Cons: "Nothing"

Pros: "The plane window seat"

Pros: "Despite delays the captain was communicative and gracious."
Cons: "Only one person was at the gate checking passports on a full flight so embarking took a very long time, making us late. Entertainment system was pay-only and the screen couldn't be turned off so we had ads flashing brightly in our faces the whole trip."

Cons: "Late by almost an hour"

Cons: "No seatback screens."

Pros: "Greg care and service from those stationed on board."

Cons: "Very long walk from aircraft to immigration"

Pros: "It was two hrs late"

Cons: "Flight was delayed. Time was posted at gate for new time. Went to get dinner and when we returned to gate saw that the time had been moved UP from previous anouncement and practically missed our flight."

Pros: "Same with the first flight leave access to the club room was amazing it was a great way to tame the Perils of travel with a long delay between flights I was able to go into the club room have Refreshments some food and sit down and relax and wait for my next flight probably the most comfortable I've been in the last 6 years of flying."

Pros: "Had own entertainment did not use however like the app availability. Considering all of the weather delays I am very impressed and happy with service."
Cons: "Unfortunately there were no hot beverages, but cold were served."

Pros: "Nothing."
Cons: "Multiple long delays."

Pros: "Good"
Cons: "Very good information"

Pros: "Snacks"

Pros: "Flight on time!"
Cons: "The plane was small and bags barely fit on board"

Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"

Pros: "Nice and happy/friendly people working for the airline..will take this airline again"

Pros: "Everyone we dealt with was unbelievably kind and helpful. They had a wheelchair at the gate and helped push my disabled brother which was such a help for my elderly parents to make their connections. When I got my parents their tickets I was very apprehensive that it might be difficult making the connections but thanks to United's wonderful service their whole experience was fantastic. In the future I will always try to book United."

Pros: "Flight was on time"
Cons: "Check in was terrible"

Cons: "Boarding is disorganized"

Pros: "Short lflight"
Cons: "NA"

Pros: "Seating was nice, middle seat was empty"
Cons: "I landed at F1 and had to run to C29. No time to even grab a snack!"
