While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

N Everything was perfect from boarding to assistance to baggage in Tampa

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I took seat 15A in anticipation of window seat, there is no window.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was canceled on Sunday. Rebooking took three hours. Had to pay for accommodations another night. New flight was delayed for 5 hours, all that was sent was a 12 dollar food voucher, which doesn’t tell you how to use it. Then when we landed we had to sit on the plane for an hour before we could get off.

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

No screens or meal options. Freezing cold. Dirty seats. Left late.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Boarding gate at LAX was too crowded—two gates next to one another

On time departure and early arrival. Flight attendant very nice.

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

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

The SFO Lounge crew were amazing. The bartender Faris was great. Thanks!

Friendly crew is the only nice thing. Seats uncomfortable. Food and snacks horrible. Movies were the same as the first 10 hour flight two weeks before

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.
