Pros: "Crew were very attentive and hospitable to the crew. I have been flying ASIANA many times and enjoy the flight as well."
Cons: "Not enough fruit & cheese boxes to reach past mid plane"
Cons: "The plane’s electrical system was not working and we sat on the plane for over an hour with no A-C. Several solutions that were tried were also broken and we were told that the plane itself need to have additional electricity to start the plane for the past 4 days! Unacceptable on a usual A+ airlin"
Pros: "I love the new plane interiors and love how you wrote about the features in the in-flight magazine. I’m a designer and it was so nice to read about why you developed those features. Love the lighting. Bravo!"
Pros: "The people at the service desk and customer service on the phone were very nice"
Cons: "Not loose my luggage. I was forced to switch flights to LA in order to catch a flight to Sydney. My bags came 3 days after I had to buy all new sets of clothes and toiletries because I went on a sailing trip for 5 days. My bag finally arrived and now I have too many clothes and an extra bag."
Pros: "Everything"
Cons: "My cabin bag has been misplaced and I siding receive the same."
Pros: "Boarding was smooth. The crew was very pleasant and helpful. The nourishment was very good."
Cons: "Entertainment was wifi based. No live TV which Virgin America used to offer."
Pros: "Window seat"
Cons: "Alaska changed my seat twice, and didn’t let me pick a seat before or at check-in"
Pros: "View out window. Legroom was good."
Cons: "Cattle car crowded, sold out flight. I usually drive or ride motorcycle to travel. I’m a man, not livestock. I need space around me."
Pros: "Interior layout was pretty cool. Like the class divider and first class seats (even though I didn't sit in them). Pre-flight briefing was entertaining and funny. Gave me the whole can of Sprite!"
Cons: "Nothing truly negative to say."
Very efficient and effective. Fight crew and captain did a good job given the weather delays and turbulence…
Pros: "Crew was super amazing and friendly! Very good service also!"
Cons: "No seat back entertainment.."
Pros: "Crew was very friendly and took good care of the passengers"
Cons: "It was fabulous as always! Thank you. I love Delta!"
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."
Pros: "Great seat easy flight. The food always seem to be the same. I wish they would change it up every once in a while. I've been on this flight 14 times this year and its always exactly the same.."
Cons: "The gate was under construction in Seattle, and it was impossible to hear the gate agents."
Pros: "Use my built up miles for the SEA-ANC leg of our trip, as to physically price it out as one ticket usually increases the fare by 300-600 u$d depending upon time of year. As it was the tail end of an already long journey (OKA-ICN/ICN-SEA), booked the First Class Cabin. Every mile was worth it."
Cons: "N/A"
Pros: "Nothing"
Cons: "I came from a long trip from France, the seat I was assigned was not reclinable, close to the restroom. I was totally exhausted from the previous flight, not able to sleep at all and when I tried to stretch my legs by sitting sidewards on the aisle a crew member keep bothering me to keep my legs out"
Cons: "We paid for comfort plus but the seats were no different than main cabin. Comfort plus experience on other legs was much better."
Pros: "The food and the crew totally good"
Cons: "Maybe the toilets, need to be clean at least once in a flight"
Pros: "Crew was super nice"
Cons: "Airline to be more user friendly with connecting to free entertainment"
Pros: "Crew was efficient and pleasant making for a good experience."
Cons: "Nothing"
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "The flight got me there"
Cons: "WiFi was too slow to be able to watch anything. Seat small and uncomfortable. Flight attendants not friendly."
Pros: "Nothing. Just the pilot"
Cons: "Everything. Bad communication. 1 h delay. Then 3 hs in the plane. We ran out of gas. 2 more hours taxiing Never seen something similar. I really hope my mileage refund."
Cons: "Boarding could be improved if they would start boarding from the back of the plane to the front after boarding 1st class and Priority this way people would not block the passage when putting their luggage in the top compartments. The crew was not very helpful because I almost went into a hypothermia condition because the air in the cabin was extremely cold. When I ask for a blanket one of the stewardesses said that AA would no longer have blankets in flight which I prove it wrong when I saw in the flight Mai-SDQ blanquets all over the cabin. The soliton they gave me was that they would ask the crew to raise the temp in the cabin, I had to make the request three times and I had to tell the stewardess that if not raising the temperature in the cabin I could have gone into an emergency hypothermia crisis. I had to take another shirt from my carry-on to put it over my shirt to warm me up."
Cons: "Not enough time in London to change planes. We missed the flight"
Pros: "For this flight I was seated in first class (I scheduled it this way; it wasn't due to a last minute upgrade) and the flight attendant was very personable and attentive :-) Service was wonderful and the meal was great! Of course, the flight attendant made sure to keep our beverages topped off as needed. It was a wonderful experience"
Cons: "The boarding process for just about any airline is nearly identical. It always seems like it takes longer to board than expected even if, in reality, it's not an unreasonable amount of time. The only think I didn't care for was that overhead storage in the area I was sitting was just about full by the time I was seated which meant that I had to store my carry on a few rows behind where I sat. This meant that during off-boarding I needed to go against the flow of people to get back to my carry on. All in all, it was a minor inconvenience."
Pros: "Awesome roomy seat right behind business class. Could not have asked for better! And it was a gorgeous new aircraft."
Pros: "San Fran to Vegas - Good Flight! Slept the whole way so no need for entertainment however - it being an United Airline Flight I assumed all of the planes would have inflight tv’s on the backs of the seats. Other than a little turbulence - great flight! Thanks for keeping my baby and I safe."
Cons: "Two hour delay. They gave us three different excuses, probably all lies."
Pros: "Crew were experienced, and worked preemptively to help a number of passengers with tight connections"
Pros: "Nothing great, nothing bad. took off and landed on time."
Cons: "paced seats, nit enough room for carry ons."
Cons: "worst flight ever .... absolutely no leg room. I am 6'5 and i sat in the last row. I asked to have a seat reassignment but the plane was full. I was miserable as hell!! I am very dissatisfied with my experience with United!!"
Cons: "Cacelled then delayed twice. United workers are also very rude. I give them a big ol"
Cons: "Now Sherry in any documentation I received did it say that my flight was operated by United airlines. I waited at ANA check in until within the 2 hour window and went around and asked someone at United who confirmed that they were partners with ANA."
Cons: "flight control forced us to miss my connection to Kansas City so had to spend $150 on a hotel in San Francisco and wait an entire day to get home."
Pros: "More important than the trip home last Wednesday was the reason for the trip. We attended my granddaughter's wedding. Everything else was secondary. Even if the trip had been in a one wheeled barrow, it would have been good. To get to what you want which is the mechanics of the trip. The two people who attended to the aisle chair, most teams were competent. Some hadn't done many passengers so they were fumbling with the straps. I've learned that I almost alway have to ask for one at the gate where they check or issue, (what's it called, loading permits, some kind of pass, not landing pass. loading pass. I can't remember and my wife has gone to bed.) Well, they have to come up with an aisle chair because I've only got 1 1/2 legs. I always make it to the seat on the plane, but the competency of the various crews is uneen. Sorry my answer is so nonspecific but I don't remember one airline from another. Great people all, get the job done."
Cons: "Not much I don't like. They get us there That is the main thing. Sometimes when the plane stops after it has pulled away from the Jet Way, the pilot gives an explanation that I find unfulfilling, not enough details. I suppose if they explained more, other fliers would find the explanation too verbose. I can live with it. Again this is about all flights and airlines. Nothing stands out, such as, " this awful thing happened when we left San Francisco.""
Cons: "Delayed getting on our way I think because they were late getting in and had to do all the plane checking. Captain said safety checks. Seat space felt tight and I am short."
Pros: "The crew was very attentive to each guest."
Cons: "Well I paid more for a lesser quality plane ride... didn’t like that very much."
Pros: "The Crew"
Cons: "It was a passenger on the plane acting real suspicious. I didn’t like that. Also the seats was uncomfortable."
Pros: "This airline is completely disorganized and with no apologies. I waited an hour in a bag drop line and then an hour and a half in the plane with no real explanation as to why. Planes are super bare bones which is fine. They just seem to be incredibly understaffed and unorganized as a company. All of the attendants and desk workers were trying their best but were set up for failure"

All of the attendants and desk workers were trying their best but were set up for failure"
Cons: "The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future."
Cons: "if flight was delayed should at least provide complementary soft drinks..."
Cons: "There was a malfunction online and I was overcharged for my flight. There were also delays going to and from my destination."
Cons: "After being left on the plane for a long time and not even offered ice water or anything. We were released out to the lobby. And then shortly after asked to get back on the plane where it was EXTREMELY Hot. I would NEVER go frontier again."
Pros: "The crew was friendly and helpful."
Cons: "There were extra fees for carry on and checked bags, which was not revealed until we printed our boarding passes. In addition, we had to pay to reserve seats. On top of that, I have never sat in such uncomfortable seats. They charged $2.99 for a can of soda on the flight. Finally, they lost our bag, after our flight took an hour longer than it was supposed to."
Cons: "The flight was first cancelled, then I had to wait two days for the next available flight out. Also was charged for my carry on bag. This airline does not offer any complimentary drinks. I will not book this company again, you think your saving a little and end up spending More at the end."
Pros: "Nice crew. Plane clean."
Cons: "On this long flight from Atlanta to San Francisco, a reclining seat would have been nice."
