My experience with Scoot is very good. Will have no issue flying with Scoot again.

My experience with Scoot is very good. Will have no issue flying with Scoot again.

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

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

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

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

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

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

Emirates is always great experience, however, they should reopen their lounge in Istanbul. The IGA lounge is not worth it

I liked everything accept the delay try to improve in that area

Flight never took off. Boarded after multiple 30 minutes interval delays for hours.. then after an hour onboard, captain announce cancellation and back on the bus to the terminal with no information and everyone to fend for self.. Emirates did absolutely nothing to communicate either electronically or announcement. It’s unprecedented I know with the flood but lack of communication creates anxiety and extra pain for staff. Emirates should do better.. no supervisors monitoring floor and passengers abusing them which isn’t right but should Have had supervisors monitoring

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

Amazing service and food. However I didn’t get chance to choose my own seat which bothered me a little.

Overall good but one thing I didn’t understand is why they didn’t allow me to pick my own seat.

Had the salad which tasted awfully spat it out but still got food poisoning 1 after running to toilet crew would not let me sit near toilets I was stuck in window seat

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

Boarding was delayed but the information about delays was not provided

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

We are satisfied with the cabin crew serviceand the quality of meals served.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

Pros: "The snacks were nice and the crew was nice"
Cons: "Boarding was TERRIBLE!! Everyone was rushing the podium and overwhelming the employees!! Basically the employees could not control the crowd. Having lanes, or signs in multiple languages for boarding zones would be helpful"

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.

Pros: "The flight was smooth. Food was on time . Wine is available for the anxious flyers who can’t sleep."
Cons: "Better softer hand soap , sprays and lotion . Sleep mask"
Cons: "delay of about 1 hour, we almost missed our international flight from beigin"
Pros: "It was a terrible, long and very crowded flight."
Cons: "The people/passengers. The whole flight felt like a budget airline. I am not looking forward to the return."
