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.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

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

Very god service with smile. Aircraft a bit old, TV doesn’t work, luckily we can use our mobile to connect to their TV.

I always love to travel with Garuda. Staff are great. On time. Efficient. food and drinks plentiful. pillow and blanket. But there were no live demonstrations of safety. I honestly have no idea where my life jacket is. On the way to Bali we werw not made to put on seat belts , although we were on the way back. What I hated this time was the waking of passengers after 2 hours for breakfast when it was still dark. Not sure if i will travel back to Aus on that flight again . Being welcomed with a breakfast 2 hours after shutting my eyes in the dark was Horrible and left me jet lagged after only a short flight.

Very pleased. Very professional and organized. Very clean aircraft. Efficient boarding and even a snack.

Friendly flight attendants, Did not care for the food. My headphones did not work because of a faulty jack at my seat.

The planes are getting quite old, the staff are quite ok good ok thanks Garuda

I liked most things except the cabin was way too cold for most of the journey. I prepared by putting on long pants, shirt, jumper, shoes and socks. Still cold!

It’s been a while and I saw lot of improvement. Flight was on time, friendly air crew, good food and comfy leg room.

For ground ticketing crew to honor the seat I’ve chosen instead of separating me from my family WITHOUT INFORMING me!

Good, ontime performance...hard products is somewhat out of date

Food quality can be improved for the price of the ticket.

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

It was ok, the additional baggage charges were a bit excessive given winter is a time for skiing. To have to pay $600 extra for skis was tantamount to robbery. Airlines should consider sporting goods as baggage. Likewise, they should consider increasing the number of bags allowed on international flights to known ski destinations.

Couldn't access entertainment on app as said in an email

A few more inches of legroom is all i ask

The flights got us to our destination. The seats on the planes were uncomfortable.

Over four hours late. No entertainment without paying and same for food. Asked to check in at original time even though we were told it was going to be very late leaving. Way too long time to hang around the airport. Arriving to Sydney luggage did not arrive for an hour. Had to get staff to go and find out what was going on. All this made for a very long day and night for a eight hour flight.

I was disappointed to find that the QR code for purchasing in-flight entertainment did not function, leaving me without access to the amenities I had anticipated. (both flights)

I had opted to pay extra for a ticket on Jetstar A321-Neo in the first row, believing it would enhance my travel experience. Unfortunately, this was not the case. The constant line-up for the toilet resulted in people frequently standing next to me, causing significant discomfort throughout the flight. It was difficult to relax with the persistent disturbance from passengers bumping into my seat. Furthermore, I was disappointed to find that the QR code for purchasing in-flight entertainment did not function, leaving me without access to the amenities I had anticipated. Given these circumstances, I will not be purchasing seats in the first two rows in the future, nor will I choose to fly with your airline again.

Late leaving and desintuon board showed ‘gate closed’ when they hadn’t even commenced boarding!

The crew were great. The seat was older than an old Holden with a big metal bar sticking right into my back. The passenger next to me complained that hers was the same. The pre purchase system for food was disappointing as the pie/quiche took 20 mins to warm up, arrived too hot and with no utensils. It was one of the most uncomfortable flights I've ever been on.

There's a reason why fare is cheap, no amenities.

Entertainment wasn’t working! It didnt work on our flight from Darwin to Bali either. They were newish planes, so it was disappointing.

The flight was over an hour late due to staff shortages and due to it being the last evening flight, I got back to Sydney very late

This was the most horrific experience we have ever had. I would advise people to steer clear of this airline at all costs.

I was pretty sure my seat includes a meal. But I guess I was wrong because I wasn't served a meal on my flight with Batik Air from Kota Kinabalu to Kuala Lumpur. I was fortunate because the layover was more than an hour in Kuala Lumpur. Otherwise, I could have cause a delay to the connecting flight to Taiwan because my terminal to board the next flight is located at different building. I had to take a train to the satellite building. Overall, all is well.

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.

Need to improve the availability of the food. Seems like everything sold out

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

Delayed for 3 hours, need to pay extra for drinking water.

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.

2 delayed flights - hotel layover in a different country- lost baggage.

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.
