Great to have actual hot tastey meal on a flight. Well done

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Wonderful service, planes and interior in great condition, very pleasant experience

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Transfer within the same terminal and lots of facilities at the airport.

I did not like anything. Flight experience was bad overall.

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

Didn’t like it at all. Cabin crew unfriendly. Very bad experience.

Absolutely terrible delays for 3 hours changed seats after we paid an upgrade on both legs. It appears it’s up to us to request a refund after they down graded our seat. Never again !!

Excellent airlines. I highly recommend using Emirates. Its my number 1 airlines

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

Premium economy on Emirate A380 is simply the best non-business class product. In fact its probably better than many business class if the seat isnt lying flat. The food and service is close to perfect!

1. Please deploy better trained and courteous staff. 2. Wheel chairs be available at all steps of layover till boarding gate. 3. Food services be also improved . 4. TV and phone charging facility be also provided.

The plane and services in Emirates flight from Los Angeles to Dubai were very good . But plane and services in flight from Dubai to Delhi were very poor/uncomfortable. Staff at Dubai and crew in Dubai plane was very very disappointing|shabby. Wheel chair was given only for a very small part of layover at Dubai and we faced great inconvenience. In short , our experience Dubai onwards(fly Dubai) was very bad and uncomfortable.

Cabin crew were not welcoming.was expecting excellent after traveling in Emirates from Houston to Dubai.

The flight was delayed in Jhb and I could have had some help in Dubai trying to get to my connecting flight to London

Good staff, good intent, decent entertainment. More seat space would always be of benefit

No towels or tissue and chocolate and mint provided before arrival

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Asian Veng meal have Non Veg items which is not ok. Pure veg meals option are too less and they have inclusion of Vedgan and Lactos etc... which is taste less

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Better service is needed. I booked for Qatar but I was switched to American way after I bought my tickets.

Fine. Don’t think I would fly with them again

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Generally good. The crew is excellent. The food could be better.

They charge me for luggage which is was included on the ticket

Business class in the second leg - CDG-EVN was a disaster.

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

No bording was given for next trip on same carrier, food was very moderate.

No birding was given for next trip on same carrier, food was very moderate.

Lost luggage, 2 bags were badly damaged and one of the bags came open.

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

Despite many attempts to work out a change, neither British Airways nor Kayak nor Chatdeal would allow us to cancel or change this flight so we lost all of the payments when we were not able to fly. Absolutely terrible customer service. We will never use either of the services again.

They sell 1h /1h30min connection ticket that are impossible to make

Seated in business class. Bed too hard and no comforter. Way too many seats in business class for number of crew so never felt particularly looked after.

My selected seat ending up being very uncomfortable both major flights. SFO to London and back. Seat arms did not go up so it was not like suggest by BA staff. On return flight my seat had a life raft barrier in front off me and large man beside me.

Biz class has a middle seat. 🙄. WiFi only for first class. No free seat assignments. Basically nickel and dime approach. They need to take lessons from Singapore Air and the likes. Never again.

I was called up at the gate not knowing why and then handed over my passport and was told I was being upgraded from Premier economy to Business class and it was wonderful. I've never been upgraded before and it was such a pleasant experience.

Great service and air hostesses, took care of all activities very well and smooth
