The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

SQ is a market leader for good reason and its 787 this time was actually comfortable and the service top notch as always.

Fast and efficient flight. Wifi worked well. Food selection could have been better

Never book through Kayak. They can offload booking to third parties that are completely horrible.

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

I take emirates because of direct flights Otherwise no Cabin crew niot friendly and never friendly across the airlines Planes old inside not renewd .. this is not an issue The issue is the poor service

I had a good experience flying with Emirates. All of the flights were on time staff was very professional and kind. So I had a positive experience..

We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

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.

Worst trip ever from the beginning to the end I will never travel with that airline again. I made a big mistake by not going with my regular schedule flight with Qatar airline. Even underpriced cheat me of my 134 dollars I paid for special seats and they kept my money and didn't pay the airline for the seats for me.

The lounge staff at reception were inefficient and robotic. Boarding process was chaotic at the gate with no priority for business and first. At arrival into Dubai, no upper deck door . Food option and quality for this flight was awful . Thankfully the bar is always good.

All was good. Emirates should restart allowing fast track immigration for business class at Manchester airport. Saves a bit of time

Check-in process at Bengaluru airport was atrociously slow. Emirates should allow baggage drop option after online check-in and verification of documents. The rest of the flight was quite good and we didn't have any complaints.

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

Quality and tasty Food and service, bigger seat comfort and leg room, etc.
