優點： "I liked sleeping"

優點： "Yes, we were unexpected and surprised being upgrade to premier class"
缺點： "no complaints. very appreciated our upgrade, since we went to Prague for mother-in-law's funeral, we were absolutely exhausted.This up grade made an excellence different to us. Thanks very much."

優點： "Punctual take off and landing, attentive crew, excellent entertainment system (Especially for short haul flight). One of the best meals I’ve had in the air too - great that this along with unlimited drinks was free!"
優點： "Food, professional staff and crew"
優點： "Legroom was generous, crew were attentive and polite, although alcohol availability was stingy."
缺點： "Food quality was poor bordering on tasteless, more importantly service of lukewarm egg meals is guaranteed to earn an "Air Typhoid" award, and is inexcusable."
優點： "We liked the boarding in Atlanta and in Seoul with the people boarding by the numbers of their rows - boarded the back rows, then the middle then the front. Worked so much better than everyone rushing to get on! Flight attendants were very helpful with everything and always kind. Loved being able to sit in the exit row seats!!"
缺點： "Food was okay - we fly Korean Air whenever we travel to SE Asia and it seems the food is the same no matter what flight we are on. We like the pizza snack better than the bun with meat inside they served us on this trip."
優點： "Same as above."
優點： "Boarded on time; everything efficiently done; pleasant staff. Breakfast was not great - too sweet overall. Usually korean does well with food."

優點： "Flight attendants are pretty and nice."
優點： "The staff were kind and very helpful when my USB port didn’t work. They were eager to fix the problem."

優點： "Very professional crew good service"
缺點： "Nothing really pilot couldn't understand him but does it really matter unless is an emergency"
優點： "All was well as usually except..."

缺點： "It was delayed for two hrs for 50mns domestic flight. An i missed connecting bus so had to pay extra 100usd!"
缺點： "Korean Air refused to provide accommodation for my 19 hours layover even I had two flights with Korean Air. The reason provided was simple: "We don't have you on the list". The fact that it's 8 pm and had known nothing about South Korea meant nothing."
優點： "Seats reasonably comfortable, service decent"
缺點： "3 of my 4 flight legs were considerably delayed, my luggage not making the connection for one of them. A friend also flying Korean also had delays making me think they are unreliable and extremely disorganized. I don't know what they'll do when they're really busy for the Olympics. Entertainment OK but ANA has much more."

缺點： "Ran 2 1/2 hours late, poor customer communication"
缺點： "Worst first class service. Only came by twice in two hour flight"
優點： "Delta Premium Economy (or whatever it's called) is definitely a step up. Food is pretty good and seats leave more room, so you don't feel crunched."
缺點： "First seat (no chance to put thngs underneath seat in front) MUST have a real space (as even economy generally has). There was a small pouch that would fit almost nothing. Staff was poor. Never a smile or friendliness from flight attendant and no help when asked."
優點： "Terrible seats! It keeps getting worse."
缺點： "Timing of leaving the airport! It was delayed and I missed my international flight"
優點： "The check in counter personnel was VERY UNHELPFUL. I was running late to previous Delta flight baggage delay. The counter person would not let me check in even though I still had good 45 mins before take off. AND THE PLANE WAS DELAYED BY 40 MINUTES ANYWAY! I never made the flight, had to take train."
缺點： "The entire Delta customer service was a nightmare. Delayed flights, literally lying supervisor who escalated a dispute, absurdly poor service. ASSISTING A PASSENGER WITH A TRANSFER TO ANOTHER DELTA FLIGHT AFTER THE FIRST ONE WAS DELAYED IS "NOT A GUARANTEED SERVICE". Seriously, it is basic courtesy!"
優點： "Seating was fine"
缺點： "Did not have a wheelchair waiting for my wife when we arrived in LAX"
優點： "Boarded on time."
缺點： "After boarding the door was closed and the jet way was moved back. 5 minutes later they said they were going to bring the jet way back and open door to let more people on board. They broke 2 FAA regulations by doing this and we were delayed an hour because Deltas computer would not allow this."
優點： "The crew were fantastic. Departed on time, arrived 40 minutes early."
缺點： "Delta One is a bit jaded on this flight."

優點： "Crew was amazing and friendly. Flight was on time."
缺點： "Had to collect & re check luggage between flights. Couldn't they have been transferred to the next aircraft?"
優點： "All okay except baggage check in and baggage claim."
缺點： "Delta Baggage handler accused my g/f of lying about active military status. Refused to accept her military ID. She is a first responder in a unit that responds to search and rescue and terrorist attacks and was returning from three days of maneuvers. Baggage lost. Still not here forty hours later."
優點： "The crew was excellent"
缺點： "We had mechanical problems and had to come back to Atlanta, get off our plane and get on another one"

缺點： "4 hour delay on take-off and despite that my luggage didn't make it onto the flight."

優點： "Nicer plane"
缺點： "One stewardess almonds mowed me down with cart"
優點： "Crew were nice. Flight itself was short. Was quick boarding considering how busy the flight was"
缺點： "Plane was very old. Seats were rigid and not very comfortable. No entertainment. Just basic really."
優點： "Boarding was super quick, as crew wanted to leave before the strong rains and winds came through, so we left early! Plane itself was very modern and surprisingly comfortable, as much as a small space can be. Good amount of entertainment, and the crew were pleasant. And flight itself was smooth with very little turbulence which helps!"
缺點： "Had to pay for food, which was a little annoying considering the cost of the flight. Entertainment was very American led... but I guess not surprising considering it’s delta."
優點： "Staff are adept at dealing with these issues but it is a systemic problem."
缺點： "Rather than pay luggage fees, people are bringing on their luggage and the flight ALWAYS runs out of space. Suitcases are being moved around right at people heads and more than once I've been hit and seen other people be hit in the head by a suitcase. Getting luggage in place used to be a simple and minor issue, now it occupies much of the time, energy, and attention of the cabin crew as well as the gate crew. I realize this is making money for Delta but the cost is being paid by people being hit in the head with luggage and the crew's unavailability to deal with other issues."
缺點： "I missed check in (not flight) by 5 minutes. Delta did nothing. I called Aeromexico. After 30 minutes on hold they told me there was nothing they could do. Called Kayak, you guys said you couldn’t do anything. Finally I got some 3rd party phone number I was given by Kayak. I called the number and it was not in service. In all my years using this app this was the biggest disappointment ever!!!!"
優點： "On time flight courteous service"
優點： "wow, got in 3 minutes early, its a short flight, but its no joke trying to get out of ATL on time! Great job!"
缺點： "Plane journey awful. Speaker had a loud buzzing noise all the time so never heard a word bad landing. Rattling plane Very cold."

缺點： "Not much- pretty great flight"
缺點： "This was my most uncomfortable flight ever. I am 94 years old and the seat was so cramped and small that the entire 3 hours were uncomfortable."
缺點： ". The flight was overbooked and I had to wait for last minute to find out weather I will be on board of the flight .My bags were left behind in Amsterdam which were delivered later than they were supposed to."

優點： "Boarding was efficient and the crew were nice."
缺點： "the seating is horrible. it was the tightest seating I've ever experienced."
優點： "Overall a nice and good flight"
缺點： "Just a detail, my “head holder” (not too sure how it is called) would not hold in position. Also, staff was a bit slow to come after being called, I had to go and ask for water by myself at some point since no one was coming after 15minites of waiting..."
優點： "Nice crew, good food."

優點： "Information sharing by pilots and crew. Economy class leg room is good."

優點： "Like the overall KLM experience"

優點： "Everything was good except for the entertainment consul for one of our seats."

缺點： "Larger meals."

優點： "Nice crew pilot food and beverage"
缺點： "No wifi"
優點： "Light snack and complementary wine"
優點： "Very pleasant, professional crew"
缺點： "Very slow check in. Mainly because other passengers obviously don't read instructions re: weight/contents of cabin bags etc. Would be helpful if there was additional staff to deal with them away from check in desk. This would mean that others did not have to queue for 25 minutes because the check in girls also had to deal with them"
缺點： "Flight was delayed, landing at vce took an additional 10 minutes due to no one at the jet way. Luggage service was very slow"
缺點： "Nothing special"
缺點： "Seats were uncomfortable"
優點： "La puntualidad"
缺點： "La comida"
優點： "Used miles to upgrade to Premium Plus. Excellent seat and food!"
優點： "The flight was easy and quick. These small planes are actually pretty comfortable."
缺點： "Waiting for a gate in Chicago is never fun. Most people on the plane seemed to have tight connections, and I'm guessing most of us missed them. I only made mine because the next flight was delayed."
缺點： "Extremely hot on the plane."
優點： "The UI to watch videos on the plane is really good. They have good quality screens, so I watched movies for all the 12 hours of lfight I had."

Five minutes before the flight, the info board said it had been moved to 9:40pm and was changed from Gate 3 to Gate 30, a very long distance to get to. However t"

缺點： "The ONLY thing negative that I can say is that the Chicago airport had no charging stations at my gate."
缺點： "After we board the plane, we were forced to sit on the tarmac at LAX for 2 hours. I missed the Ferry to Provincetown and it cost me an extra night of hotel in Boston. The food choices were very limited, and the seats are just not comfortable at all!"
優點： "Da food, seat"
缺點： "Da Music"
缺點： "Food was horrible. Then for 2 of the 3 meals they missed even serving some rows entrees."
缺點： "Delayed for an hour, sitting on plane. Not enough leg room."
優點： "My bag made it onto my connecting flight in spite of the tight connection due to the delay."
缺點： "The gate attendant asked if I would be willing to move to a different aisle seat to allow a family to stay together. She told me it was the same seat, saying "aisle for an aisle." It wasn't--it was the worst seat in the house--last row, next to the toilet, smelled the entire flight, with no possibility to recline. I had booked my seat months in advance, so a concession offer, such as a food/drink voucher, or a seat in econ plus, would have been the right thing to do. Instead I felt like a tool. Makes me wary of doing something nice for the airline in the future. No plugs in regular economy class makes it hard to use the United app for entertainment. Also, kept getting bumped off the wifi app."
優點： "WiFi free"
缺點： "Unfriendly crew"
優點： "I enjoyed the food and the movie selections the most."
缺點： "The seats and and the temperature. I had a really sore butt and tired back by the end the flight. The temperature of the flight seemed to be alittle too warm for my liking as well. Blankets and pillows were provided but were definitely not needed as it was too warm to use them."
優點： "Left on time, friendly crew, comfy flight."
缺點： "For reasons I still don’t understand my baggage didn’t travel with me and I was not able to get it until several days later"
缺點： "2 suitcases out of 6 came broken, the airline did not accept any claim because they say the type of damage is not covered!!!"
優點： "You didn't let me of a schedule change on my fight, make wait another day. Now more delay today"
缺點： "No entertainment screen on each seat, just old TV far away. Very boring on this trip"
優點： "I enjoyed the movies, food and assistance"
缺點： "There was nothing that I didn't enjoy about my trip"
缺點： "I think, on a five hour international flight that you should not have to pay for your entertainment. Really cheap. And if you have a couple of kids? Since the Go App works for free in the states, why can't they offer that."
優點： "Everyone was pleasant."
缺點： "Delays due to staffing issues led to missed connection and 7 hour wait for next available flight."
優點： "No problems with connections or staff who wheeled me from place to place."
優點： "The crew was very pleasant, food was average."
缺點： "The flight being cancelled. Wifi doesn't even come close to working. No personal entertainment. Communication was poor for the rescheduling of flight that led me to miss the next flight"

優點： "Snack, mints"
優點： "Comfort and food"
缺點： "wasn't comfortable and didn't have USB to charge"
優點： "The meal that was served was exceptionally good."
缺點： "Is it really that much more expansive to provide complementary movies - personally I never watch the movies but many passengers do - I did not notice anyone who purchased this service."
缺點： "Last minute terminal change AFTER having gone through security at another terminal made the trip quite stressful."
缺點： "中文廣播人員結結巴巴都在亂翻譯，太不專業了 服務人員一直玩，講話好大聲，讓人不能休息，很不舒服 大家下飛機時，每間航班都會很有禮貌一直謝謝搭乘，UA871我沒感受到。"
優點： "The entertainment worked for like most of the time (surprisingly) and I got an extra seat next to me."
缺點： "What can you expect from united... the crew members were terrible absolutely unprofessional and unwilling to help. We were delayed for 3 hours in Taipei due to an issue with the plane that they were trying to fix. During this time many people were trying to change flights as they had connections in SFO. When they asked the hostesses for help, they either got rude unhelpful responses or got completely ignored. United really needs to train their flight attendants better."
優點： "Not much, except maybe the price."
缺點： "Rude ground staff (air staff were nice). Several delays and not organized at all."
優點： "Flight was shorter than expected"
缺點： "Bathrooms were dirty and sound wasn't working for first in flight movie"
缺點： "Being stranded for 2 days due to so called yoo many Inbound flights. WTF. Had to fly out with delta."
優點： "A smooth easy trip from Chattanooga to Newark."
優點： "United is definitely improving. The service was attentive and friendly. When I asked for PJ's, the flight attendant made a good effort to retrieve them for me. I slept through the entire flight, very rare unless the conditions were optimal for sleep."
缺點： "While this flight was fine, my flight to Taipei was riddled with poor service. A bad and forgetful flight attendant can make all the difference. As United adjusts their service to the new Polaris configuration on newer planes, conditions will hopefully improve."
優點： "Easy buddy"
優點： "The seats were uncomfortable. The staff was cold. The food was horrible, I wasn't even able to eat some of it. The chicken was full of bones and grissle. The rest just tasted bad. Most of their planes did not have screens in the back of the seats. Instead they wanted you to watch on your personal device via their app which worked sub par. The baggage on the return flight was delayed and I almost missed my next flight even though I had a 2 hour 40 min layover. Thankfully that flight was delayed 1 hour and a half. Next time I will stick with airlines I know better. Delta, Emirates, and Qatar all offer superior service and upscale aircraft. The 2k spent was not worth what I received."
優點： "The flight crew was very professional. Both of my flights departed and arrived on time."
