Pros: "empty plane"
Cons: "food"
Cons: "Hour delay before departure; 30 minute delay after landing before we reached gate; 15 minute delay to get carry on bags!"
Pros: "We didn’t crash and die. That’s the only positive."
Cons: "Before we boarded I listened to a couple described how they always went ahead in line at boarding because no one ever stopped them. They described how they waited until group 3 was called and then went right through. While we were waiting, we watched them do it again. If you need to cram people into tiny spaces to be profitable, then you cannot allow them to make it worse by putting back their seats. I spent 90 minutes with a seat back jammed into my chest. We were ignored when handing out snacks, probably because we were invisible behind the seats pushed in our faces. It was one of the most miserable flights I’ve experienced."
Pros: "Great first class cabin crew."
Pros: "Attentive crew. Traveling with 2 seniors in their 80’s. Thank you."
Cons: "Nothing. Perfect."
Cons: "Boarding was a hassle and the plane was extremely uncomfortable for a 4 hour flight"
Cons: "British Airways flight was carried by American Airlines. Planes were late, boarded one plane from the tarmac with no explanation, gate was changed 5 times without announcements. Will never fly American Airlines again!"
Cons: "One of the seats in fseat"
Cons: "The DVD/ movies was having an issue.., couldn’t play.. I had to ask to have it reset a few times."
Pros: "Crew was great. Made sure I made my connection. Even tried to get me a better placement so I could quickly exit and head to my next flight."
Cons: "It wa super cold on my second flight. Small plane, rather loud."
Cons: "As a handicaped disabled not able to walk and should be using a wheel chair,as I know from my many previous travels with other companies like lufthanza, klm..etc, I used to be the first traveller to go to the air craft when loading it to take off and the last one who would be leaving it after landing. Even when going through the check and security points I used to go in a special route especially for the handicaped but going with all other normal travelers lines with such amount of time waiting and crowdness is completely inconvenient. what happened through the trip was quit different , going with the travelers or after when they are boarding the craft make it very hard and time consuming , Wish you take care of it, as it's a very important handicaped service. Thank you for taking the time to read my comment"
Pros: "Quick boarding"
Cons: "Before the flight boarded the crew had to be paved. They were busy chatting at a different gate while the whole flight had to wait for them. No sense of urgency. Very unprofessional. We had the front seat in first class. All night long the crew were talking loudly- difficult to sleep. They should be conscious of the passengers"
Pros: "Everyone was super friendly. The plane was clean and comfortable and the food was great for airplane food."
Pros: "I liked the room."
Cons: "There was no entertainment. Could not get seats together."
Cons: "Flight cancelled and had to travel 60 miles at my expense to a different airport to get another flight same day"
Pros: "Crew was nice."
Cons: "Having to check my carryon even though I was in the 12th row. I saw some passengers putting two items in the overhead, which makes it unfair to others."
Cons: "Very upset with baggage handling and charges for baggage on an international flight. I bought an economy fair but was not well informed about fact that charges for baggage would be made. I ended up paying more in fees for baggage and seats than if I had purchased a "regular" coach fare or had flown on another airline. Will do this next time. Also, both my pieces of luggage were damaged and not properly latched following opening by security."
Pros: "Flight was comfortable and enjoyable. Entertainment was great lots of films to choose. Service by the flight crew was excellent"
Cons: "Nothing"
Pros: "This was a nighmare!"
Cons: "My flight Paris/London/Manchester?Chicago was the mos impleasant experience I ever had. On July the flight was schedule for 9...pm then delayed for two hours because of a fire, other passengers said, in London. At around 11pm, we were asked to line up for boarding. We stayed on line for an hour and fnally to be told the flight was cancelled. We were treated less than animals by British Airway. No ACCOMODATION!!!!!!!! No ACCOMODATION!!!!!!! We slept on benches at the airport. To be fair to you, I will not recommend British Airway to anyone."
Pros: "My flight was delayed and expected to delay further and the attendants put me on another flight to get there before my connecting flight."
Cons: "My bags never made it and when I arrived, I was told that one of my bags was still at my departure airport and the other wasn’t scanned."
Pros: "The comfort of the plane and the continued update on my flight delay."
Cons: "The flight was delayed but no fault of American."
Cons: "The vegetarian meal is always vegan, I miss the dairy :("
Cons: "I missed all my flights and my bags because of a stupid delay made by the airline."
Pros: "The flight entertainment is really nice."
Cons: "Boarding seemed very chaotic as staff tried to get people to check bags at the last minute. My chair would not decline properly."
Pros: "The flight was not filled with passengers, so a number of passengers had a whole row of three seats in the Dreamliner to sleep on."
Pros: "Entertainment on screens"
Cons: "The gate agent made us starting in boarding group 6 out of 9 to check sizes of bags in the size box and she got into a verbal fight with another passenger. One guy told her she could board but the gate agent said no it didn't fit and she couldn't board. Then the agent claimed she had to gate check her bag and claimed there were no overhead spaces left. So everyone after that had to gate check. When I boarded there were at least 8 empty bins and I had not even gotten to my seat in row 22. The gate agent lied and slowed down the entire boarding process because she want to win a fight and show dominance over a passenger."
Pros: "Great aircraft, UK staff kindly assisted to get us family seating near each other"
Cons: "A passenger caused a delay in security, and as I'm rushing for the gate, the agent closed the door and told me I couldn't board. She then marked me as a no-show, while she was standing right next front of her. I had to spend the next 4 hrs on the phone, trying to get my tickets sorted out. Then, upon arriving at Heathrow,... No luggage. They told me it was still in Chicago. Upon finally receiving my bags, I find them full of sawdust and sand, and several items damaged. I will NEVER fly American Airlines again, and I will highly recommend to my friends and family to avoid them like them plague. Horrible service! Nothing but a run-around and not once did the agents apologise, even after admitting that my problems on this journey were due to a mistake made by one of their agents."
Cons: "The only complaint I have is our bags getting lost twice. I’m very understanding that these things happen. But for it to happen twice seems like people might be careless to the problem."
Cons: "The crew waited until we where onboard about to leave to defrost the wings, making us 50 min late. Half of the plane missed their connecting flights"
Pros: "Easy and smooth flight."
Pros: "No complaints. A smooth flight. Met my expectations. Would fly American again."
Cons: "Airbus seems to have completely minimalized all legroom for persons over 6 feet."
Pros: "Great service!"
Pros: "Current movie selections"
Cons: "The seats are cramped. They served the final meal very close to the actual landing. The legroom is not comfortable enough for an average size adult. i asked the attendant at the gate for a seat change but never heard back."
Pros: "Crew fantastic , food good"
Cons: "Limited seat space"
Pros: "Seats were more spacious and a representative was great about helping us find seats close together for a party of 4 that had originally been split up."
Cons: "No sort of real line before boarding. Other customers were getting in who had numbers that were not yet called. Staff at the inside gatealso gave very short answers."
Pros: "Boarding and flight were on time."
Pros: "Nothing it did not exist"
Cons: "You cancelled my flight without telling me"
Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."
Pros: "Very nice staff"
Cons: "Nothing"
Cons: "Rude staff, they changed our flight 2 times and did not offer a drink or food"
Pros: "Staff members went above and beyond expections; accomodating some seating reassignment requests, charging customer phones, and being very responsive overall."
Cons: "It would have been nice to at least have USB chargers in economy class."
Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."
Cons: "They had no record of this portion of my trip, after a few people checked they found the Chicago to Ammon part so they added me onto a flight from Washington to Chicago. All should of went well from there but they sent me to the wrong gate. Luckily I just made it to the correct gate for boarding. Upon arriving at Chicago there was no one available to provide information on how to get to Royal Jordanian gates. Also on my AA portion of my flight coming into The U S in New York the flight was cancelled and I was told the next flight Available was next day (18hr delay) at the other NY airport. I had to have someone drive from D.C. (My destination) to pick me up"
Pros: "Comfort"
Cons: "Nothing at all"
Pros: "The staff were amazing. Very accommodating and with great dispositions. Boarding was easy."
Cons: "For an international flight the seats were extremely tiny and the plane itself only had a few tv screens posted in the middle of the plane so everyone had to watch the same thing."
Pros: "I thought the crew was friendly and the food was pretty good."
Cons: "The plane did not have personal TVs, which means they showed a handful of bad movies overhead and on a nine hour flight, it's hard not to be able to pick a movie or pick a TV show."
Pros: "Flight crew very welcoming, flight was pleasant."
Cons: "Seating a bit tight. Didn't offer any snacks only ice water."
Pros: "Nothing"
Cons: "That it got cancelled"
