It was good but n it to the same standard as London to Singapore

a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

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.

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

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

It was very good experience on board to Sydney with SQ.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Once again the meal served was delicious - we got chicken rice

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

55 min transit, not sure how they planned to make it work

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

I think it is much better than the flight I flew from Sydney to Tokyo.

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Well my expórtenle with Qantas it wasn’t that good KLM from Bs Aires was delay Santiago Chile Qantas QF 028 was still in the airport but the crew didn’t opened the door for me soo I lost my fly And I stuck in the airport 13 hrs waiting for next fly by Latam Arline My question is can I have my money back for business class

Flights were delayed, Food was good but only 1 meal instead of 2.

We are row 11, when the crew came to us, only one meal choice was available.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

Did not take as cancelled 3 time so took another airline

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

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.

No recognition for one World Emerald member. Business class seat has flat bed

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

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

Sri Lankan airline had less entertainment choices and Sri Lankan national carrier did not have language choices

Very poor. The flight was delayed for over an hour. Also, our baggage, including that of many passengers, approimately 180 bags did not arrive, and we are yet to receive it.

Poor, They have damaged my luggage and I have filed a claim at Colombo airport. They promised I will be in touch by the team within next 2 days but there is no One contacted me at all after 1 week. I then follow up again and received an email acknowledging my claim and claimed that they will reply in 12 days on investigation. Again, no response at all after that… Very disappointing…

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

The staff was absolutely phenomenal but the other elements of Sri Lankan Airlines need some serious adjustments. The day started off with terrible news that the flight was cancelled from Male and that the plane went to Malta. As an American, when such delays occur, the airlines find suitable ways to accommodate their customers such as putting them in an Airport hotel or lounge while waiting for the next flight. A 1.5 hour trip turned into 12 hours with no accommodations from the Airlines except a ticket to eat breakfast. For such a Billion dollar industry, a cheap breakfast is an insult toward the customer and something greater should have been done.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

My flight from PEN-KUL was re-timed for two hours or so due to some technical issue. It was not conveyed accordingly by the staff. Info only received via fellow passenger who also mentioned about the possibility of changing flight but different airport SZB. Changing flight is not easy since everyone is fighting for available seat unsystematically. Anywhere, I and my wife managed to get seat for slightly earlier flight from the retimed one. The issue should be handled more professionally and systematically.

Freezing onboard and staff refused to give me hot water “because we were landing soon”. The plane arrived at the gate an hour late. And there’s an air leak in one of the bathrooms. Very scary noise.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Did not like that we were not informed about the 4 hour delay, crew not friendly, noone at terminals to consult with...all employees for Batrik were behind glass aftervgoing through security at the gate again. Why no agent at Gate H 10 to answer questions? And no apology. Updates would have eased anxiety. Boarding is disorderly also.

During this flight all the crew just focused on making money by selling food and drinks. There was only one washroom open. And it really smelled bad and wasn’t usable. Even to watch something onboard entertainment u have to rent headphones pathetic airline but only one with direct flight so pretty much the only option from Karachi to KL

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

Silly to not even offer people water for free when they are paying so much for tickets.

You get what you pay for. It’s functional and gets you from point A to B in good comfort. However, food options are limited and cash only, Crew is a hit and miss .. they get your attention if you reach out.

Good leg room ... air conditioning was a bit warm don't Book row 8 ... no windows

The worst kind of budget airline. To be honest....the plane was not that bad. Would have been good to have some food choices and some water. What was by far the worse is the passengers/customers that this airline attracts. Coughing and spluttering all over one another with no masks. Just disgusting. Pay for a better carrier and get a better class of passenger.
