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

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 🙏

No frills airline with minimal leg room and no entertainment

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Best service airline. The cabin crew is attentive and friendly. Inflight entertainment system is good

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Both flights to and back from Lyon with buses taking extra time and delaying flight at DXB. Food serving needed work.

The main issue was that the flight from trivandrum to Dubai was delayed which resulted in arriving late in Dubai. Coincidentally the flight leaving out of Dubai to jfk was also delayed for different reason. Despite we reached the gate ( through wheel chair assistance) along with 10 other passengers we were not let in. The gate was open and yet was refrained from entering. We were then requested to flight the next morning. Meal vouchers were provided but the hotel reservations were not made and took a lot longer to receive that. If Emirates knew about the delay and was certain the passengers will not be able to board the next flight shouldn't they have prepared these ahead of time?

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Wonderful Premium Economy experience. Felt as good as Business Class for food and entertainment. Comfortable sleeping too

The 2 sockets near me didjt work i had my phone by end of the flight on low bat and had issues to book uber thereafter Electrical sockets should work if emirates does not allow batteries Baggage claim in zurich took very long

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Fantastic service the managed to locate my checked bag on the plans as re-tagged it for my final destination.

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

The queue for checking for economy passengers was enormous! Only one desk open for economy faith s queue a mile long, whilst business and first class desks empty and unemployed. Will seriously consider changing to another next trip. Disappointed customer.

Very pleasant.The crews are very helpful.Food are very good.

Easy boarding and friendly crew. There is no food offered as it is a short flight and no entertainment either…but a good experience overall.

A very nice flight. It arrived on time, and the plane was very clean and the staff was very professional.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

This is a very short commuter flight, so there is no food or flight entertainment. Hence, I marked it in the neutral flight left on time. The plane was full pretty much and it was a pretty easy flight overall very good.

The flight crew and attendants are very professional and polite.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

For a domestic flight, seats are ok, but fir us as tall dutchies, the legroom is too small. However, for a short and affordable flight, is not a big problem. Staff is still very nice and a complementary water very welcome.

2 hours delay, time changes started already 2 days before the flight

Average, not more then that. Cannot compete with Singapore Airlines

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Not even water is free on board. Very cheap airline!

Quick and easy, short flight , 30 minutes. Staff was friendly, no food or drinks in this very short flight.
