Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

My bags were misplaced!!! Im in a foreign country with no bags

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.

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

The business class layout of chairs was weired. You are sitting directly across stranger.,

Flights on time w/o delays. However, my baggage was damaged. Ground crew, throws baggage from plane to the baggage carrier, carelessly.

I’m sure Business Class would be excellent. I feel like I got what I paid for. Overall it was good and well worth it. I would do it again.

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

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

I was able to get the AA customer Service desk to put me on an earlier flight without any issues.

The seat was comfortable, the attendants were very nice and WiFi made my life so much easier with work. Kudos!
