Cons: "The flight was delayed over two hours"

Pros: "Pilot explained the flight path and landmarks along the way. Crew was friendly to us and welcomed our baby onboard before many other pax boarded."
Cons: "Seats were narrow and I’m not a big guy. 6’0”. 185."

Pros: "comfort plus really makes a difference"
Cons: "include at least 1 checked back with comfort plus or some kind of discount."

Cons: "Plane left 4 mins early knowing that passengers were on a delayed flight."

Pros: "Information communicated about delays."
Cons: "- more communication (any!) about bag status when landed - flight delay due to too many/too heavy baggage. Long delay was said to be due to making sure our baggage would accompany destination. Upon arrival, bag was left in NYC but this wasn't communicated. No info on bag status at airport or via ema"

Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"

Pros: "Very good"
Cons: "Seat assignments should have be provided at check in."

Pros: "Crew were very pleasant and seemed to enjoy working"

Pros: "Everything went well."
Cons: "Friendlier faces. Seats that work better. Was clear on the reclining operation"

Pros: "Crew was great."
Cons: "Couldn’t hear/understand the pilot"

Pros: "The crew was dealing with NOVA/DC residents"

Pros: "Coming from Europe Alitalia and Delta did an EXCELLENT job at assisting the passengers get rid of their luggage just as soon as we were done going through customs... I don't usually fly on this route, but I thought it was perfect. Transfer between Delta terminal was a breeze too..."
Cons: "I usually don't fly from JFK. The food court was expensive (18 dollars base price from a burger seems a high even for an airport. I don't fly from NY normally - so maybe I need to tune my expectation for the locale, and it may have NOTHING to do with the airline company."

Pros: "Lots of in flightentertainment options"

Pros: "The service is very good from the beginning. The flight attendant is very caring thanks so much."

Cons: "The aircraft is too old, MD-88. I don't know how Delta is flying that type of aircraft. Is very risky"

Pros: "Another safe flight. Crew was very attentive."

Pros: "Crew were great"
Cons: "Very cramped I was at the back of the plane"

Cons: "Flight cancelled due to weather that was never bad but on the potential of bad weather. Had to scramble so my 18 year old son was not stranded overnight in a strange place and Delta does not help. Only rebooked a flight itinerary for the next day for a 4 hour flight with connections on a 1 hour direct flight. Spent an hour on line to figure out what to do. #neverdelta"

Pros: "Nothing"
Cons: "Plane delayed 4 times for a total of 4 hours"

Pros: "I love flying Delta and my flight to Australia was incredible. I like the fact that I can check two bags free and the free inflight messaging and entertainment. Some of the staff were very polite and friendly."
Cons: "The seat I was in was broken. It moved and I was stuck sitting on metal. There was no leg room. The plane used going to Australia was a lot roomier this plane was old. Some of the flight attendants were very unfriendly and seemed to be bothered by the fact they had to do their job. The entertainment system had to be rebooted multiple times and the usb on the seats didn’t work. They ran out of food during lunch."

Pros: "The flight for getting us therw"
Cons: "No food and no entertainment"

Cons: "Flight was delayed until it made me miss my connection"

Pros: "Friendly and courteous crew, great food, comfortable seating, quick luggage retrieval. Wow!"
Cons: "Nothing."

Pros: "Fantastic Pilots and a great flight attendant."

Pros: "How nice and gentle they were."
Cons: "Long waiting lines."

Pros: "Delta in general but , they let me stranded, i had to find a eay to fly home, they did Not help finding a next flight.. i missed my flight because of WX"
Cons: "Lack of interest towards the passenger and client, i had to do it my self"

Pros: "great flight free movie going down"
Cons: "no free movie/tv coming back"

Pros: "i liked that staff and crew were very communicative and pleasant."
Cons: "one crew member didn't show up and caused delayed flight."

Pros: "Everything was fine other then seating assignment"
Cons: "I was traveling with wife but was not able to seat with her. I was stuck in the middle of 2 of the worlds biggest plus sized people. Armrest was a constant struggle. Willing to pay more next time to avoid hassle."

Pros: "The crew was friendly, relaxed, made everything seem like a breeze"

Pros: "The entertainment"
Cons: "We didn't get our seat assignment until we got to the gate. Attendant said it was because tickets bought too close to take off don't get to pick seats, but we bought our tickets about three weeks before. Also, my boyfriend and I sat in a full row while the row in front of us only had one person. It would've made more sense to put that person in one of our seats and us in that row to give four people more space instead of just one."

Pros: "I could be wrong, but the seats were very comfortable (for a plane) and I felt my knees weren't as close to the seat in front of me than other airlines. So that's a plus."

Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"
Cons: "On my first flight they forgot to turn the wifi on. I have unlim data but obviously can't use while in air; no big though."

Pros: "flight attendants were great."
Cons: "not enough leg room and space. The business class should be at the minimum for economy."

Pros: "The agents in the air were a lot more understanding and at least apologized."
Cons: "I understand if we need to check bags because its full but when iy is not full but you demand I check it anyway all you are doing is adding travel time to my trip. Also we needed things in our bags that we otherwise would have had. Not the best customer service at the gate."

Pros: "The crew was polite and friendly"
Cons: "My second plane had sooo much moisture coming from the cooling system it looked like the passengers were getting gased and I kept getting wet from water condensation falling on me in a window seat as I tried to sleep from having such an early flight to begin with only to be told it's delayed 3 hrs without explanation."

Pros: "Good seats."

Pros: "Free drinks in Comfort+"

Pros: "The crew was incredibly helpful assisting my last minute boarding needs. Staff was friendly and polite."

Pros: "I love the new entertainment sysem"
Cons: "Only one service on such a long flight? Should have done a second beverage service."

Cons: "For the second time in one day, my seat would not recline!!! Very uncomfortable for an even longer flight than the first one!!"

Pros: "Pretty much nothing related to the entertainment system... It is nice that you can play movies for free over WiFi on your phone or tablet (since the in-seat system simply didn't work...), but, bizarrely, the WiFi movie selection was different from (and substantially smaller than) the seat movie selection. What's that about? And the WiFi movie scheme is way more painful than it needs to be, requiring you "check out" movies using your web browser, then switch to a separate app to actually watch the movies. Clearly the product of a company mindset whose ONLY concern is "can we check some box", with absolutely no interest in "how can we delight our customers?""
Cons: "So we get the same entertainment system all these flights use: some ghastly totally non-optimized Linux setup that was rebooted three times during the flight, took 20 minutes for each reboot, and never worked correctly after any of the reboots. (The only movie my system would ever play was the very first one, and none of the on-screen controls worked. The seat next door could choose multiple movies, but each movie froze after 40 minutes). The amazing thing is: why don't they just install a damn iPad mini or Android equivalent in the back of each seat? Would be lighter than what they have today and would work FAR better. You'd need some co-ordinating/provisioning software to provide for OTA announcements and movie updates, but basically it's not that hard... At the very least, hire a Linux-head to optimize your startup scripts! It's just sad to see this 20 minute startup process (all dumped on the screen) with its constant repetition of time-wasting startup steps that just generate errors on this plane's particular hardware setup..."

Cons: "See above description"

Pros: "The seats were comfortable, service was good, movie/entertainment selection great. Logistics for flight were awesome, there was no long layover."
Cons: "The extra fee for check-in baggage."

Pros: "Upgrades, staff on and off the plane"
Cons: "The reservation system crash, it happened less than 24 hrs before our return flight to come home, fortunately it was resolved but it was a bit stressful"

Pros: "Flight attendants were great."
Cons: "Movie and TV selection is not great for an international flight."

Pros: "Comfort with entertainment."
Cons: "No food options at all."

Pros: "Pilot has very smooth landing. Crew were nice"

Cons: "Reasonable price"

Pros: "The boarding was pretty good for this flight, seemed simple enough, everyone was pleasant. And I was near an exit, which offered sufficient leg room."
Cons: "I was disappointed by a few things... 1. The staff didn't much care to be there. They seemed distant and unconcerned, although their words were supportive. I just got off a flight from Seoul to SF, with United (892) and they admittedly stated that they were understaffed (which was completely fine) and their attitudes were much more supportive than that of the following team (486), a flight from SF to IAD. 2. I was surprised, that on a 5hr flight, they only offered a half bag of mixed items and two rounds of beverages. I was sure that they would feed us something. However, if it's not the policy, I get it...but I asked if they had anything I could purchase, the flight attendant points me to the menu pamphlet and says that I could choose from there. I asked for the Chilled Chicken with Slaw and she promptly lets me know that they only have cheeseburgers, a protein box and Cheese. For a person who's lactose intolerant, I was again disappointed by the service--why ask me to go to the menu, if you knew there were only three items you were offering?? So I didn't order anything. 3. The entertainment blows my mind. I've flown with you guys like 8 times this year, and the app still does not work properly, however, before every flight, someone mentions over the intercom to be sure to download the app...but if it doesn't work...why offer it? Also, if there are tvs at the back of every headrest, the least you could offer is a random movie, versus the commercials about how great the app is, or whatever was scrolling along. Lastly, please note, I was trying to figure out a way to make a comment to United...but didn't want to sound TOOO disgruntled. I'm not opposed to flying with UA, absolutely not, but if any of these things are addressed, I definitely feel you will be making a massive improvement on what seems to be an airline that I'd think twice about taking. Feel free to e-mail or call me. I don't mean to sound rude...but having flown other airlines, and knowing that UA has been around for a while, i just hoped the experience would be better."

Pros: "Left on tarmac for 20 minutes prior to takeoff. Late flying into IAD with no guidance from crew or ground crew with very short time to catch next flight. With no info, felt abandoned."
Cons: "Lack of info from United crew."

Pros: "The crew was friendly and helpful. We were always informed of what was going on."

Cons: "Wifi access"

Pros: "I did not like any part of the trap maybe when they offered us some preferences that was included in the fly that's about it"
Cons: "The flight was 3 hours delayed the text message updates said we're not accurate"

Pros: "The flight attendants are very hospitable..The food was good..The flight was so good it was a very good experience. We are lucky to choose ANA."
Cons: "None."

Cons: "This flight was cancelled."

Pros: "The plane was clean and the crew were pleasant and polite. I was a little surprised that the pilot announced they wanted to leave early; there were a couple of announcements about that while we were boarding. When we arrived at LAX there wasn't a gate available, because we were early, so I don't think we gained anything other than a feeling of being herded quickly."
Cons: "Entertainment options were limited; Friends and Big Bang reruns plus some music videos. According to the app, these don't work on Windows 8, which is what I had. The seats are cramped with very little tilt. I had an aisle seat and was hit by nearly everyone walking by, even though it wasn't a rough flight. I would rather not fly with this airline; I don't see anything that they do that would encourage my return business. Frankly, I've had better flights on Southwest!"

Pros: "Timely and comfortable. Landed ahead of schedule"

Cons: "The small commuter planes used for the trip are not smooth rides at all. Very uncomfortable"

Pros: "Willing to drive to Charlottesville. Difficulty finding one way rental"
Cons: "Above"

Pros: "The crew was great."
Cons: "We had a long delay with the cabin so I missed my next flight."

Pros: "Iad to Boston on board attendants"
Cons: "Flight timing excellent"

Pros: "The professionalism of the airline stewardess says that's what I like the most"
Cons: "I really can't say that I truly would call something I didn't like"

Pros: "I like the crew. They were very friendly and great."
Cons: "The entertainment was terrible. On the way to Amsterdam, it was an old TV that had a few channels that looped the same thing over and over again. On the way back to Washington, DC, the TV didn't work."

Cons: "Almost everything at United is horrible,the space between chairs is a big joke is impossible to move , if you sit on back you probably don't have a choice for food or drink you have just the one nobody want"

Pros: "Staff were helpful, the flight took off on time and the trip was smooth."
Cons: "No complaints on any front."

Pros: "Good flight"
Cons: "Nothing"

Cons: "there was no in-flight entertainment for the duration of the flight."

Cons: "need to do pre assigned seating during the purchase of the tickets"

Pros: "finally reached our destination"
Cons: "germany was apparently having a strike. all flights were cancelled. we were made to wait overnight. then sent to frankfurt. then sent to venice. couldnt land there. we landed in bologna italy. then made to wait overnight. then we flew to rome. then we flew to chisinau... finally. what was initially supposed to be 18hr flight. turned into a 5 day trip. i want a refund!"

Cons: "The worst part was the new seats are the smallest ever. I could not sit without my knees jammed into the seat in front of me, and on both legs, Ithe seats were narrow that the people next to me and I were overlapping shoulders - that was a first. Unless its flights in the future are significantly advantageous, United's losing my business. It's not worth saving a few bucks to me to be so uncomfortable."

Pros: "Good service, good movies, fast flight"
Cons: "They could not get the sky way to work AND we had to take the Dulles bus then escalators then train then escalators and still a fair amount of walking and waiting to get to ground transport-- 1 hour from landing!"

Pros: "Crew was solid"

Pros: "United crews use to tell me you couldn't preboard with children but they must have changed that policy because they allowed it this time."
Cons: "They always ask a second time for the boarding pass after the first agent scans it. They should tell you to keep it out if they are going to review it a second time."

Pros: "Nothing"
Cons: "Late"

Pros: "Everything was fantastic"

Pros: "The crew that helped get everyone booked on another flight did an outstanding job. Too bad we had to sit around for 3 hours to find out that the flight was canceled."
Cons: "Not enough communication as to the flight being canceled. Too long to inform us that it was canceled. We were told that the flight was always on time with the exception of the past few days. We were told that the service was starting to slip."

Pros: "The duration of the flight - no stops"
Cons: "The food was poor, the airplane was an old one"

Pros: "Aircraft was fairly clean and staff was courteous. Good entertainment options"
Cons: "1 hour delay after boarding on time. Rough landing."

Cons: "No snacks offered on the plane"

Pros: "The whole trip was easy and non dreadful"
Cons: "None"

Cons: "It was late boarding and landing. Our bags were sitting in the rain."

Cons: "Maintenance delays and rerouting caused me to miss my reserved ground transit in LA... United claimed on the phone I would be reimbursed for a taxi, but changed their mind when I sent them a receipt a few days later."

Pros: "sufficient space for luggage overhead"
Cons: "too much chatter among crew, especially during boarding and disembarking rest rooms too small - claustrophobic additional, and roomier rest rooms could help wish announcements could be delivered more slowly, better enunciated, and less slurred; often cannot be understood; one often has to guess the meaning more smiles and friendlier tones and attitude could help having window seat can be very inconvenient when leaving one's seat"

Cons: "No TV"

Pros: "Quick short sweet flight"
Cons: "Boarding late"

Pros: "Got there."
Cons: "Small, cramped seating. Outdoor jetway upon arrival."

Pros: "They boarded is quickly"
Cons: "Plane was delayed on runway for over an hour. When the passenger next to me asked the lead flight attnd about her connecting flight the attnd was extremely rude and of no help. Any ? was answered with "well just look at your united airways app". Then later I asked what gate we were coming in on and her reply was "the capt just said it". I replied saying "sorry I didn't hear it" and again the flight attnd answered "look on your UA app". I don't usually fly UA so I didn't have it. Overall she was short, snarky and rude with ever reasonable question asked. No one was rude to her but her attitude was shocking. I travel quite often and have never seen an antd speak or act this way to passengers. I understand things get stressful, but I def won't be flying UA again if this is the way they allow flight attnds to speak to customers. She way beyond rude and lazy and I hope the girl she was training doesn't pick up those traits either."

Pros: "Airbus is the best commercial way to travel"

Pros: "Fast, friendly, on time"
Cons: "None"

Cons: "Nothing"

Cons: "Broken WiFi"

Cons: "Flight cancelled- rebooked then delayed 9 times- sat in airport for 12 hours for a one hour flight!!"

Pros: "Courtesy and smiling faces"
Cons: "I was sitting in the last row facing the economy class, the divided curtain wasn't wide and thick enough to give you some privacy."

Pros: "United made arrangements for me because of the flight delays"
Cons: "The first flight was delayed 4 hours so United got me a taxi to Dulles to catch my next flight. It worked but then that flight was delayed one hour."

Pros: "We were well compensated for a traveling fiasco. Our plane died in Newark. Our new plane wasn't big enough for 12 of us. It was a pretty crummy to spend Easter Sunday at the airport while our entire family celebrated the holiday. I do really appreciate the travel certificates we received for our trouble."
Cons: "As I stated above, we were stuck at the airport for the duration of Easter Sunday. We were supposed to be home by 1:30pm. Kind of a bummer to have wasted the entire holiday; but I guess that's what you get for traveling on holidays."

Pros: "I liked that your beverages are complimentary"
Cons: "1 ply toilet paper is unexeptable"

Cons: "I paid the 25.00 for my small bag which could have easily been a carry on, but I had a purse and small carry bag. I felt that WAY too many folks had backpack and two small carry ones, but by bringing them to the gate - the announcement was made its a full flight so you can check your bag for FREE! Next time, I will not follow the rules and just simply check at gate?? That is message loud and clear from your gate folks."

Pros: "Loved the fact that there was leg room !!"
