second leg was more comfortable. Customer service in Abu Dhabi is okay.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Took a long time for boarding. The flight was comfortable.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

The flight attendants were rude in the DEL to FRA flight. The transfer between the two flights at Frankfurt International Airport was an unpleasant experience. The airplane was never parked at the terminal, but was deboarded instead on the tarmac itself. For those passengers in need of a wheelchair, it was a nightmare to come down the stairs and then rush across the airport to catch the connecting flight from FRA to IAH. Upon arriving at IAH, it was informed that the luggage had not arrived. Would make it a point never to travel with Lufthansa again.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

Flight ride was good, crew members were great however they need to hire some better food caterer.

You gave me a “Never fly Lufthansa” experience for life. You charged me $1760 for reinstating my ticket on a cancelled flight. Service at the airport was terrible. I’m convinced that I should never fly Lufthansa.

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar

Food quality deteriorated after Tata aquired the airline. No alcoholic drinks till last meal on a long haul 15 hour flight. Entertaiment systems needs a complete overhaul.

Flies in the flight, broken seats, broken entertainment system and display - worst flight ever

We trusted KAYAK and Air India but no one is responds for the lost of baggage 🧳 2 (bags). My in laws are totally lost hope for this kind of situation to travel any more.
