They should resume the fast track for business / first class passengers

Emirates is superb service. The A380 was very comfortable. The cabin crew is really helpful

The plane seemed pretty old and the food was not good

The plane was clean and well maintained the crew members were professionals and friendly and the food was good

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

Flight was on time. Seats (economy) were very comfortable and food was excellent. The bad thing was that after landing it took an hour to reach arrivals. We had to wait 15mins to get off the plane and then had to board a bus which moved very slowly and took almost 30 minutes.

We boarded via a mobile gate in Dubai. I don't care for the bus ride from the gate to the plane

I wish Emirates had lights to Philadelphia (PHL) in USA.

I was not allowed to upgrade with miles whereas others were. That’s a pity

More leg room or a bed hahaha but in all was one of the best flys I been on

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

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".

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.

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Doha airport is huge , takes long time to reach gate .

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

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

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

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.

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

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

Was got free upgrade, on old A320.aircraft is out dated kind of.bt service ,cabin manager, tried there best.and food was excelent.

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

The crew did not really interact with me which was no problem as I was fine. I did see that they were somewhat short with some passengers but that was not common. Just in general, they did not seem friendly - no requirement to be so but I am used to a friendly crew on most flights. The food was just ok but with a flight that large, I would think it hard to make something more elaborate.

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.
