Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

Excellent service, I love the soft blush pink mood lighting on the 767-400ER during meal service. The overhead gasper vents on the 767-400ER were also very strong with a lot of airflow to keep me comfortable on my flight.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

I am still at the Airport! Delayed Delayed and Delyaed

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

The entertainment options on the seat back video boards were nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

Due to cancellation of connecting flight (Lufthansa) I didn’t fly with United

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Vegetarian selection could be better. Bread was too hard to chew.

All went very well. We used the AIFI Airport, such a lovely facility. Definitely needs better transportation options to get there.

Both ground crew and flight crew were rude, and did not provide any level of service. They made it very difficult as we were traveling with a passenger the required assistance.

From the check-in, to the flight, and arriving, everything went very smoothly. Unfortunately, when I received my baggage it was severely damaged. I have a hard shelled suitcase and it was completely smashed it. I’m not sure how this could happened but I am extremely disappointed that my belongings were damaged beyond repair and continued use.

Really nice, all good, nice crew and all on time

Unfortunately I had an awful boarding experience. Our first flight with Aeromexico was fine and landed on time however it couldn’t find a gate and we were late which made us lose our connecting flight with Aeromexico. The staff handled it horribly when we explained our situation and would not led us board when we missed the boarding time by a couple minutes. The staff were extremely rude and did not attempt to even help us. Because of this incident, my husband and I missed a full day of work which negatively impacted our salary which we need. Please compensate us for the work that we missed.

It was OK. The flight is pretty long for the airlines to only offer a simple sandwich on business class. The entertainment is similar to that on other Skyteam members. Ultimately the airline lost my bag and didn’t deliver it to me until the next day after a lengthy lost baggage report.

Good, the flight from Miami to Mexico City was better than Mexico City to Miami

Aeroméxico cancelled my ticket without advice AND It make a last minute mess in my intinerary, no solving my situation, bad advice and bad customer service

Flight was on time, good service, but there was no free WiFi, even for first class passengers

It was good in general. The Crew during the flight were very nice at all times.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

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.

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.

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

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

I am writing to share detailed feedback regarding my recent journey with American Airlines on the New York (JFK) to New Delhi (DEL) sector, which was ultimately diverted to Jaipur (JAI) due to weather conditions. At the outset, I would like to acknowledge that this was a full long-haul flight of approximately 14–15 hours, and while the journey fulfilled its primary transport objective, several aspects of the experience warrant both recognition and constructive feedback. 1. Cabin Crew Conduct and Service Consistency While the majority of the cabin crew maintained a polite and professional demeanor, one flight attendant’s conduct was notably inconsistent with expected service standards. The tone was often directive and lacked the warmth and guest-centric engagement typically associated with long-haul service. This created a perceptible imbalance in the cabin experience. Although other crew members acknowledged and apologized for the behavior, it highlighted a gap in service standardization and supervisory oversight. 2. Inflight Experience (IFE & Comfort) The inflight entertainment system was unreliable, with content failing to load consistently throughout the journey. Seating comfort in economy class was below expectations when compared with other international long-haul carriers. Cabin environment management at times felt unsettled, with noticeable noise and movement in the aisles. 3. Disruption Handling and Communication (DEL Diversion to JAI) The diversion to Jaipur due to weather was understandably beyond the airline’s control. However, the handling of post-diversion communication and guest management was an area of concern: Information during and after the diversion was fragmented and lacked clarity Limited guidance was provided upon disembarkation regarding next steps (transport, accommodation, onward travel) Ground coordination appeared inconsistent, with hotel partners and passengers receiving incomplete or delayed updates Communication the following morning remained unclear, including last-minute changes to transfer timings This resulted in avoidable uncertainty during a critical disruption phase. 4. Positive Acknowledgment – Ground Recovery Arrangements It is important to recognize that despite the initial communication gaps, the overall recovery framework was eventually well executed: Hotel accommodation was arranged efficiently Meal vouchers were provided appropriately Transfers between airport and hotel were organized in a structured manner Given the sudden and large-scale disruption, these arrangements were commendable and reflect the airline’s ability to operationally recover once systems were in place. 5. Recommendations for Improvement In the interest of strengthening the overall customer experience, I would respectfully propose the following: Service Delivery Reinforce consistent cabin crew service standards, particularly for long-haul sectors Enhance supervisory presence to address outlier behaviors in real time Inflight Product Improve reliability of inflight entertainment systems Reassess economy seating comfort for ultra-long-haul routes Disruption Management Establish a more visible “Care & Coordination Team” during irregular operations Ensure clear, centralized communication (single source of truth) for passengers and ground partners Provide structured briefing points to hotel and transport vendors to avoid information gaps Introduce proactive guest engagement (clear next steps, timelines, reassurance) Closing Reflection: While the journey was impacted by both controllable and uncontrollable factors, the overall experience would have been significantly enhanced through greater consistency in service delivery and more structured communication during disruption. I appreciate the efforts made by the broader team in arranging accommodation and onward logistics under challenging circumstances. With improved coordination and alignment, the experience can be elevated to match the expectations of a global long-haul carrier. Thank you for your attention to this feedback. I trust it will be received constructively and contribute to ongoing service improvement. Warm regards, Soosnata Chowdhury Convert effective for airlines) Or tailor tone

Wifi was spotty. Tray table was very dirty when I sat down.

Flight was extremely hot and they made us check our bags when the space was nowhere near full

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

For an international flight the seats were smaller than most flight I have been on in economy. I don’t know the size of the seats or perhaps it was the size of the seat dividers that made the seats feel smaller and little amount of space to even turn your body if you needed to

My flight from LGA was cancelled and my rebooked flight from JFK was delayed numerous times. I will now be getting home after 2am.

Flight was delayed half hour before boarding, but when I checked flight aware the plane that would Pick us up had a delay of more than an hour. AA should let us know in advance to avoid waiting several hours in the airport

Not really sure I enjoyed the flight at all. The flight attendants seemed a little tired and rude at times. The snacks were lacking in taste and sustenance. The flight was incredibly turbulent for three plus hours and the pilot had to do a second pass to land at our final destination because he was coming in so fast. He must have taken a short cut and because of it we had to suffer the violent turbulence and the dropping down. It had to be one of if not the worse flights I have ever been on and have traveled vastly all over the world.

Aging planer and NO wifi on a 14 hour day flight. Unless you are retired or don't need to work or be in touch with the world... The lack of Wifif really ruined the flight. And the old plane - really showing it's age, wasn't great

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.
