Great flight with a terrific crew. Uneventful and early arrival. Thank you.

Flight was delayed. Then eventually cancelled. The female staff that was announcing overhead was unprofessional. She was telling everyone that the company is not going to give any money for taxi, hotel etc. then eventually the flight was cancelled.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

My business class seat was inoperable and unable to recline for 10 hour flight.

Okay considering we had weather delays which the Pilot notified us of immediately!

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

Stop changing gates. Stop cancelling flights Stop moving my seat.

Flight was warm for first few hours and quite rough

Never got on it. Was re-routed through Detroit and am still in airports 12 hours later waiting for my connecting plane to arrive.

It was good. The leg room was not great in Row 1.

Same day canceled, we were never informed and had to pay more with worse seating on another airline.

The economy seat was much less comfortable for an international flight in terms of recline and moving space when food tray is expanded. Per entertainment, it would be amazing if I could connect my Bluetooth headset or ear phones to the entertainment screen. Or provide in-flight wifi to connect directly from my own device.

Horrible, absolutely horrible. The airline overbooked the flight, did NOT assign seats and boarding was a hot mess with lots of confused passengers. There was no "large plane" gate for us, the 500+ passengers were squeezed in a small hold room area, and multiple busses had to shuttle us to the other side of the airfield, where boarding of the plane, that was parked on the ramp, took place in rain. The old plane had a broken seat, that the technicians tried to fix - with no success - resulting in a 50min delay. The flight attendant with heart shaped earnings with German flag was screaming on the passengers without a reason, was extremely rude and entitled the entire flight. The food was junk. I hope I don't have to fly United ever again.

The clerk at check in for my bags was very rude. My credit card was hacked during my vacation and she told me it was not possible to pay in cash for my bag. “You bought the cheapest ticket, you should have bought a ticket that included a bag. If you cannot pay with a credit card, we will not let you on this flight”. She spoke to her supervisor and then told me , I could ask other passengers, if they would use their credit card to check my bag. I had to beg 5 different people, till one agreed to use their credit card. I payed them cash of course. This was a very stressful and humiliating experience for me. I strongly suggest you build in some kind of provision for travelers who got robbed.

Terrific in every way. On time, professional staff, multiple movie options to select, great food and drink.

Business class would have been better , poor quality blanket , services

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

We got to get extended leg room in Econ plus that was great. It was nice having our own dietary needs met with our meals, and the connecting flights had it as well. Only negative were the seats my bottom was/is really sore after a ten plus hour flight. Those seats are horrible, understandable for as many people use them. So we are going to purchase a gel seat pad.

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

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

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

I understand that there is a catering issue - water should be the minimum stock. During the flight, not once that the attendants came through with water. The conversations in the kitchen were very loud and they were swearing. I do not expect any white glove service, at the minimum, we should be cordial. It was almost an inconveniece that we were on the flight. And it made us feel if you even dare question us, we'll make you deplane.

The baggage claim experience was poor. The plane crew and the AA app said that checked baggage in CLT would be at carousel 7 but the sign at Baggage Claim said carousel 1. The carousel 1 sign had the correct flight # listed above the belt. But the luggage never came. I went to an AA baggage claim office after about 1 hour and the clerk directed me to another AA room that was poorly marked, with a closed door and no obvious way to know what to do. Finally someone opened the door and my bag was inside. The clerk was totally unable to explain why.

The flight attendants as well as the gate agent were out to lunch. Nothing extraordinary about their service. American just keeps getting worse every year.

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Very nice staff, terrible food, not very comfortable premium economy.

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

Excellent. Thanks to United Star Alliance, since economy was overbooked, I’m grateful to have been upgraded to Business Class.

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

Disaster. Downgraded. Zero apology. No effort or coordination between gate and crew. Awful seat blocked by door emergency slide box. Iberia is a mess. App never works. Avoid this airline.

The crew were excellent, smiling and kind. The seats were good for economy though my seat back got a bit sticky from getting out of the reclining position. The food was good for a Kosher meal, better than usual. Entertainment was okay, but there was no Wi-fi available the entire flight. Overall the flight was fine for an overnight flight. The flight attendant in my section was absolutely delightful.

Fortunately the departure was delayed as I had a tight connection and the incoming flight was delayed. The departure delay helped me to make my connection. Thankfully, my luggage also could be transferred in the same time. The aircraft had to be changed and the power outlet in my seat didn’t work. Again luckily as the flight was not full, I could move to a different seat where the power outlet was working.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

No food, no entertainment, but that's normal for short-haul flight.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Everything was great…Flight Attendants were specially friendly and helpful.

Catastrophic experience the gate selected customers were picked up to.pay 70 eur for overweight 1-2 kg. While some others were let to board without chcking their carry on bags. Unecessaey drama by Lufthansa that brings nothing just hating them by customers.

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Not great!!! Seats in Business class were horrible; no cushion!!!
