Airline reviews

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

Good. No issues except a slight delay. Crew came in late.

Not a pleasant experience, service was poor. Didn't like it

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!
