Everything I was good except food quality is very poor

Flight was delayed by and hour but were informed beforehand

Emeritus is ***** Fly dubai is 0 we need better service for Fly Dubai

On this flight, about the last 2 hours the captain kept the cabin too hot. It appeared like the ac was off.

Emirates is always a pleasure to travel on. From the spectacular First and Business Class configurations of your big A380 and 777, to the Bar Lounge to, of course, your impecable on board flight attendance and their iconic uniform, now also even available for young girls. All the destinations that Emirates offers makes it an airline of choice many a time.

The ground staff on Islamabad is horrible. The on board services are excellent.

Enough vegetarian food was not available on the flight for all vegetarian guests on the plane. Crew did not adequately handle this experience

The food options for children is limited The business class bed is not fully lie flat, and this is an uncomfortable sleep

Not too happy with ground staff at Dubai airport. We had asked for wheel chair, and we were told to walk a long distance, poorly organised. And then at boarding to Mumbai flight wecwere treated rudely by the local Emirates staff forced to check in our cabin bags, we told them we were transiting.

‏One of the worst flights I took in My life, delays after delays, then the AC is not working and we were living in a sauna,& we were sweating like pigs. and this even before take off. Next we arrived late one hour late, baggage claims worse than the delay itself add to that one more hour to get our luggage. I am extremely disappointed and my experience is I’m never going to fly on Emirates airline. Immigration was the only good thing about this trip. It took us seven minutes to go through to the luggage claims.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

As gold member there is no priority checkin. Meaning you either have to board with your zone or last with business class pax. As economy pax all the baggage bays are filled by the time you arrive

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

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 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.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

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.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Not worth pay business classs and get service economy class

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

Make sure to request a vegetarian meal in advance. They printed out menus for all passengers with the options but by the time they were halfway through (for breakfast and dinner), the vegetarian options were already all taken.

Boarding process is one of the worst i have ever seen. Poor planning and lack of experienced staff is vert apparent. Seat changes till the last minute was an added stress to the process.

Bad service and food was not good. Give very less food.

The flight was delayed so connection was missed. In Istanbul we were taken to a hotel and no one in the hotel knew so we had to wait hours in the lobby of the hotel while the airline and hotel coordinated. The airline staff is rude at times

For me it was a good experience… thank you Turkish Airlines

Old aircraft, very very low business class standards, no privacy between the seats, horrible old TVs, tiny bathrooms.

Very good except the boarding process too forever and wasn’t organized by group. I had a heavy pack or I wouldn’t have minded. I was in business. There were no audible announcements in the waiting area about boarding and everyone packed into the boarding area. Then boarding stopped for a long time but the staff made no announcements to update waiting passengers about the holdup. The flight was good after we got on.

Professional & courteous cabin crew. Food was very good even in economy class

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

No longer a premium carrier and no better than the low cost .
