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

6.0 GoodAnonymous, Apr 2024FRA - BER

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

They made me check my carry on even though there was room We un boarded in a strange way but overall it was good

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

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.

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

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

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

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

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

Increase the number of available films, including variety. All other aspects were great.

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 :(

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.

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

Efficient like all the other flights with them. An outstanding budget airline!

Excellent service. departed on time, and arrived ahead of schedule. The whole restrictions around no food/drink is a bit weird even with Covid. Also, no mobiles and iPad use during takeoff and landing is very 2006!

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.

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 .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."

The plane had a technical problem it would delayed 10 hours but they just gave limited information and put all passengers into the Miracle lounge. Ther were not enough chairs and so on.

Ensure there is a choice of food for all customers and also enough food

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

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

No space in between the seats as per them the average height of human is 5’3” and weight as 55, so seats are designed as per the same. Also, the aircraft was dirty and full of insects

when we arrived at Taipei no one help us to get boarding pass. we saw a few people there asked them for help but they just ignored us. There was a guy told us to call Starlux number to get help but we don’t know how to dial the number until there was a lady working there helped us to call Starlux customer then someone came down took us to another counter for boarding pass. Very confused and inconvenient. We might not choose Starlux again in the future.

There was no entertainment and food option limited But the service was first class on an economy flight

They didn't have a vegetarian food in spite of the ore order

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.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

Entertainment system was too old, crew were unorganised during boarding

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

Legs space in the business class cabin is too small and pillow is dirty!

Flight from Shanghai to Kuala Luumpur delay byy 3.5hrs with no real explanation.
