Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

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 🙏

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

We started with a 2 hour delay due to some airplane technical issues, and while we got a little snack pack, it was a pretty long delay for SQ. The flight itself was short, there's no entertainment on the B737-800 and there's a small snack. Functional.

The food provided was not as good in the previous trips!

Very nice experience in business class. Flight attendants were attentive. Foods and beverages were very good.

The plane was old so the entertainment system was difficult to operate. The crew did advise earlier. The plane was landed and parked away from the gates, which added 20+ mins to the overall arrival

everything was great. I don't use on-board entertainment at all (I just read or sleep), but I appreciate that I couldn't hear anyone else's!

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

The flight experience was good, but connection time was cut shorted because of delayed start.. it would have been helpful if the flight showed which gate/terminal we need to go for connecting flight and flight timing was less than 30 minutes to connect which made ourselves stressful to catch next flight 😔

Worst ever. No assistance and communication from Emirates crew. No visibility of when the flight is flying. Couldn’t understand if we can go to lounge to take rest. Emirates system at a certain point said flight is not operating and suggested to take the next flight and in few minutes it suddenly opened the gate for boarding. unsupportive and rude crew. Worst experience ever. Flight was delayed by 5 hours so need the compensation for that.

No entertainment u less you pay. Wish there were some free movies

Overall emirates continues to amaze me with their. Awesome service . I had shifted away from emirates , because I lost luggage and watch in emirates in 2019 that drifted me away from this airline , but I am willing to give it try

Overall experience was bad , one does not expect after travelling for 14 hrs in Boing 777-300 ER to be pushed in to a craft with a extermly poor seating pitch, no room for hand baggage in the luggege bins and extermly poor service quality. This patch made my overall expereince mediocre and would definetly look for better choices when flying in or out of Delhi in future.

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

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.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

Really good 👍 This was our first time flying with Vietnam Airlines. It was a short domestic flight, so no meal service, but boarding was organized and the flight departed and arrived on schedule. The flight attendants were professional and neatly presented. All in all, a very good first experience. We would recommend Vietnam Airlines.

The flight crew and attendants are very professional and polite.

I am a bit upset with the check in counter, I signed up a wheelchair for my mom so they wouldn’t grant us her boarding pass. We got to the airport a couple of hours earlier and they had us wait and no one ever gave us her boarding pass or the wheelchair, I had to go back and complain when it was already time for our flight to board. Since we got their earlier, I could have easily pushed my mom myself and we could have relaxed and went to the lounge while waiting… when I finally got someone to help us he couldn’t explain how and why they dismissed us in the first place.

I had sometimes my trips with Vietnam Airlines and I like it 😊

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

Technical problems checking in. Had to wait a long time while they got things ready.

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

They asked me to go down to economy when i booked for comfort class

Crew excellent calling me by name ! Only downside was no inflight WiFi

Boarding and flying on time is the most important need of passengers they did that

The PAL employee who assisted my minor children went above and beyond her job and our expectations! Sophia was kind, courteous and made sure my children were taken care of!

Bad experience... Flight schedule should be on time, ours was 2 hours delayed both ways ,Mla-Panglao-Mla. Priority lane for Seniors & PWD should be practice but our Panglao-Manila flight, both priority & regular lanes boarded the at the same time, the only difference is that we were coming on 2 different lanes. It depletes the purpose of priority lanes.

Poor check in attitude , terrible food , movies selection poor, food came out cold , service terrible , entertainment system also broke so we had to use a iPad , worst biz class I have ever been on

Not a pleasant experience from the start of booking first flight all the way through to the actually flight. Only saving grace is the food.

There is a problem with the sound while watching movie or listening to the music ( the sound is static & goes on and off). Aside from the sound, the experience was good & stewardesses are nice.

I thought it was inappropriate that crew let some passengers in the back in full rows move to empty premium exit row seats when others had paid a lot for premium seats.

Everything was ok except that one of my checked in baggage which was new lost 2 of its wheels and so I filed a complaint and hope they would give comoensation. otherwise, everything was good!
