Cons: "Delta.... they’rrrrrr Grrrreaaate!"
Pros: "Most of the crew was great with the exception of curbside check-in in Denver."
Cons: "Curbside needs to stop chasing cash tips and do their jobs. If they focused on that tips would be easy to come by. The curbside attendant that took my bag didn’t even bother to check my id. He asked me my name and asked where my destination was. I told him Cincinnati as a layover then LaGuardia where he said that was wrong. He then proceeded to print a boarding pass that wasn’t mine and load my bag into the conveyor. Not 5 mins go by when I realize what happened I wound up having to go to special services to rectify the situation. Which ultimately consisted of me waiting another hour in LaGuardia to get my bag. Please delta have these curbside handlers actually want to do their job and stop chasing cash tips."
Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Pros: "Crew was friendly and efficient."
Pros: "Good"
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: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."
Cons: "Delayed 4 hours"
Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Choice of healthier snack"
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."
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"
Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."
Pros: "Friendly cabin crew. Early am departure. On board entertainment is a great selection of movies/TV etc. Clean aircraft. Comfortable seating. Great flight."
Cons: "Had to wait for the crew from another flight before boarding p"
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"
Pros: "Nothing"
Cons: "Frontier canceled the flight. Delta delayed the flight that I rescheduled. One of the worst traveling experiences I have had in a long time. My day started at 3:30am. I’m just now going to my hotel at 12:40 am"
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..."
Cons: "Engine problems-2 hour delay"
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: "Please see above. Sherry was amazing"
Cons: "Plane was small and older but it was a short flight"
Pros: "Great people and crew early arrival nice passengers"
Pros: "Nothing!"
Cons: "Everything"
Pros: "Delta is great"
Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."
Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
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: "Entertainment system is awesome and similar to what I usually see only on international flights."
Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "I didn't like anything because the fly leat 3 hours"
Pros: "Smooth ride. Delta got everything right from takeoff to landing."
Pros: "Reassignment was pretty easy."
Cons: "No accommodations were available for overnight stay due to delayed flight."
Pros: "Upgraded to first class"
Cons: "No entertainment system, no power outlet...for first class this is disgraceful"
Pros: "The flight crew was great"
Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."
Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."
Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"
Cons: "After paying for first class round trip airfare, we were given seats in coach in the rear of the plane, in spite of empty seats (plenty of them) in first class and economy comfort."
Pros: "Flight attendants were lovely"
Cons: "Nothing"
Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."
Pros: "Flight took off on time and arrived about 30 minutes early."
Pros: "The flights back to anchorage were much better than the flights out of anchorage. They were on time and everyone was very helpful."
Pros: "The on-board crew were great. Super friendly and chatty. Almost a WestJet feel instead of the serious aloofness that AC is known for"
Cons: "The entire HUGE MESS from booking til sitting on our last airplane. The “new reservation” system is a horrible joke. The right hand doesn’t know what the left is doing so you get completely wrong info and they won’t do anything about it. I’m a wheelchair assist and had to call 6 times to remind them to put it on my ticket even though each time I was shown that it had been added. They kept seating on the back row of the plain and blamed me for not calling ahead to “let them know I was wheelchair assist so they could reseat me” BUT...they won’t answer you call unless it’s 24 before your flight and then to check at the airport who then tells us it’s out fault cause we didn’t call more then 36 hrs ahead...YOU CANT CALL THAT FAR AHEAD...and ...get this “they don’t have wheelchair assist on my ticket/file”. I about lost my mind over the hours on hold and every different answer as to what what to do and in the end blamed us. ASTONISHING TO ME. THEN THEY HAVE THE NERVE ON-BOARD TO ANNOUNCE THEY ARE THE BEST AIRLINE IN NORTH AMERICA 2019...HORSE PUCKY!!!"
Pros: "We didn’t crash."
Cons: "We continue not to crash."
Pros: "Entertainment options"
Cons: "My wife’s screen did not work. The pitch between the seats was too narrow for a transatlantic flight. Older plane that needed to be cleaned and updated."
Pros: "Smooth as you like"
Pros: "nothing"
Cons: "See above - seats worn out, entertainment worn out, Crew battling old tired aircraft. Massively overpriced. Bring on WestJet direct to Ottawa."
Pros: "Food served was excellent"
Cons: "The TV screens are very dark and hard to see"
Pros: "Super easy flight with no hiccups"
Pros: "The seat beside me was vacant, so I had extra room."
Cons: "Flights in the late evening from Toronto to Ottawa always seem to be delayed. We spent a lot of time boarding, and a lot of time de-icing before take off. There would have been plenty of time to serve refreshments during de-icing. But refreshments and dismemberment of ear phones only began once the plane was airborne. There was not enough time to service all the passengers at that point. I'm not sure why Air Canada cannot at least give you ear phones when boarding. And why cannot refreshments be served during de-icing?"
Pros: "Air Canada is fantastic. Will never use air india."
Cons: "I liked everything about AirCanada and nothing about Airindia."
Pros: "First flight comfortable fast clean aircraft Second flight older plane small not as clean"
Cons: "Air canada has a problem at every arrival gate each time we landed there was no sttebdebt st the gate and so we sat on the tarmac fir a while while they awIted somebody to come and drive the Jetway to allow us to park and deplane This happened all three times"
Pros: "The full experience"
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: "Arrived on time"
Pros: "Didn't actually take this flight due to a missed connection."
Pros: "Wasn't too late. Plane seemed clean."
Cons: "Seated beside a young child with behavioral problems. Father mostly slept. Child stood on seat and jumped up and down, crawled under seats, threw ipad on my foot repeatedly, spilled his drink all over himself and his seat, screamed whenever his seat belt had to go on or his table top couldn't be down. At one point, the dad lost his temper, swore at the child, and covered him with a blanket in a big screaming match before doing up his seat belt--I was afraid he had smothered him but it had the effect of calming him down. No attendant even tried to intervene apart from asking "can I see your kid's boarding pass?" People should have to disclose when they are travelling with a child with severe behavioural problems and attendants should rescue anyone forced to sit beside one or at least make the parent care for the child. Also, a minimum of crackers or pretzels would be nice with drink on 5-hour flight. The entertainment system wasn't operating correctly and kept having to be reset by crew or reset itself. And, after first class etc. board, why don't they board the people at the back of the plane first, not the ones at the front? It took forever because people in front zones hadn't settled into their seats before people from the back zones tried to board."
Pros: "Entertainment"
Cons: "too hot in cabin missing brewage onboard"
Cons: "The crew didn't finish the inflight service so a bunch of us didn't get drinks or snacks. This was all the more frustrating when the flight then circled Ottawa for 20 minutes before landing."
Pros: "The flight was perfect. Stress free. I will definitely get it again."
Pros: "I think cost me without needing to go back and forth"
Cons: "N/c"
Pros: "On time Excellent take off and landing Good service"
Pros: "Everything, good food, good people, good times"
Pros: "Online booking,boardong pass, alerts"
Pros: "same as above"
Cons: "same as above"
Cons: "They lost our checked baggage. Luckily we did get them back within 20 hours."
Pros: "Seats were pretty comfy, snack provided even though the flight was short"
Cons: "Cabin could have been a little cleaner before boarding"
Pros: "good overall...so MUCH BETTER THAN Air Canada rouge service we took from Ottawa to Venice. Rouge service is very poor!!"
Pros: "The pilot and the crew are very proffesional."
Pros: "Everything on time"
Cons: "Nothing"
Pros: "Cleanliness, crew (in general)."
Cons: "Problems with entertainment system sound seem to be a recurring problem aboard aircrafts - the jacks seem to be in bad shape in most, whether for the provided eraphones or those brought on board."
Pros: "Air Canada is not a goo Air Lines for customer service."
Cons: "I do not like there customer service policy."
Pros: "Airbus 380"
Pros: "Same as anove"
Cons: "Nothing"
Pros: "Service was poor. Attitude was less than enthusiastic."
Pros: "Leg room adequite."
Cons: "Only beverages served, there wasn't the usual snack."
Cons: "No monitoring of travel route"
Cons: "Movies and audio lacked currency, simply old and little variety."
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: "Great crew. Nice airline."
Cons: "Both flights were over 30 minutes late. Otherwise they were just fine."
Pros: "We left and arrived early, the seat was surprisingly comfortable (it helped that there were lots of empty seats, including next to me), my full-size carry-on fit easily in the overhead bin, despite it being a small plane, the in-flight entertainment was always on and pretty good... everything went well."
Cons: "Only the things I've grown to expect on any domestic service (e.g., no food)."
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."
Pros: "Great service on a quick flight"
Cons: "There was no access to movies."
Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."
Pros: "as above"
Cons: "nothing"
Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"
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: "We boarded quickly. That was nice."
Cons: "The plane was old and tiny with barely any room for carry on. And no in flight entertainment or WiFi or anything. Bummer."
Pros: "Excellent stewardess. On time."
Cons: "Drop-off bagage agent made me line up to get a new baggage tag even though my luggage had been checked up to my destination via COPA Airlines. A United Airlines check-in agent told me that the baggage agents don’t work for the airline therefore didn’t know what to do. These people need add training."
Cons: "Wouldnt refund my ticket or change my flight when I needed to change it fee for everything"
Pros: "Staff always amazing."
Cons: "No Wi-Fi available."
Pros: "On time flight"
Pros: "Kayak provided excellent info during the trip about flights timings ! Marvelous !!!!"
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: "The planes weren’t overly packed and everyplane was on time"
Cons: "None"
Pros: "Everyone was really nice."
Cons: "Not enough free food options for active duty flyers."
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: "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: "It was fast"
Cons: "Nothing to complain about"
Pros: "I typically dont fly with united, and this was a typical experience, staff was not friendly, terminal and gate change at last minute after I walking all the way to the gate, then another delay after we were boarded, now this was more airport related then United, but after they told us it was a 45min delay someone asked if we can use our phone or computer and the answer was a stern no with no explanation until someone got really upset, just not a professional experience, and this was why I don't fly united. But I had no choice this time."
Cons: "Excellent"
Pros: "Quick Hop"
Cons: "Just a quick hop to Denver"
Pros: "I really liked the flight attendant. He was funny and kind."
Pros: "Had a flight delay in csprings but United had plane going to Denver for delivery they put us on no one missed their connection yeah!!!!"
Cons: "This was a good trip! No complaints ."
Pros: "Status quo"
Cons: "Flight was late arriving to gate hence late leaving, had a connecting flight."
Pros: "My flight out of COS was delayed by 3 and a half hours yet my connecting flight was on time. They were unable to get me another connecting flight without me being held up and landing at the wee hours of the morning. It wasn't until I demanded an upgrade from United that I was placed on an American Airlines flight. This would never have been offered if I didn't go off on the representative and demand it. American Airlines saved the day! Never again will I fly United."
Cons: "Everything.. flight never happened. Upgrade was never offered until I demanded it. The experience was so bad that I will never book with them again. They also still owe me my baggage fee back. That should be interesting."
Pros: "It was two hrs late"
Pros: "COS airport security was friendly, cooperative, helpful. With first flight since knee replacement I was worried about getting through security. TSA personnel were very patient."
Cons: "Seating was tight. Not sure how anyone could watch movies because the screen is so close to face."
Pros: "Flew to Austin instead of Houston because of weather. Then flew to Houston after 4 hours chilling on a plane in Austin!"
Cons: "Flight missed and now sitting here in an empty airport waiting for my next day flight at 650PM. Btw all local hotels are booked. Thank you United for stranding an active duty Soldier!"
Pros: "Nothing."
Cons: "Multiple long delays."
Pros: "Flight on time!"
Cons: "The plane was small and bags barely fit on board"
Pros: "I cancelled that flight... Hope my refund is coming soon"
Pros: "It was a small plane and it made up for some lost time in the delayed departure. The one air stewardess was also nice."
Cons: "Waiting for hand luggage on arrival slowed me down to catch my connecting flight. The flight was delayed to start with."
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: "The steward was lip scyncing to the safety rules which kept our attention!"
Pros: "United made it so easy to check in & get our boarding tickets. We were traveling with a child and it was a good first time experience!"
Pros: "Went fine...short only 16 min flight"
Cons: "No food :("
Pros: "The crew was nice"
Cons: "It wasn't on time to board"
Pros: "It was quick."
Cons: "I had to RUN through the airport to get connecting flight. I had to pay and check a carry-on because my first flight was delayed and there wasn't time to wait for my bag. If I'd have known I'd have taken a regular sized suitcase."
Cons: "Boarding is disorganized"
Pros: "Short lflight"
Cons: "NA"
Pros: "My flight wasn't full so I had no one sitting next to me."
Cons: "Snack wasn't very good"
Pros: "On time and friendly crew."
Cons: "Boarding group."
Pros: "Nothing"
Cons: "Everything. I had a very tight schedule to visit my friends in canada. What was supposed to be a quick flight turned into almost 24 hours of travel and ariving 12 hours late. I was lucky to have 3 days in with my friends now i only have 2. Not to mention what was supposed to be an inexpensive trip turned i to an expensive one when you are forced to eat airport food after being constantly re routed. I bought my ticket based on ariving to ottawa in the morning this however was not the case. I will be seeking a refund."
Pros: "Well organized, enjoyable flight"
Cons: "Na"
Pros: "Snacks is good and healty."
Cons: "CRJ700 seats are like sitting on naked plywood. Very uncomfortable."
Pros: "Time and confort"
Pros: "Nice employees"
