Traditional economy class. Not a full flight so spare seats. Food and drinks were good

10.0 ExcellentPeter, Jun 2025MEL - HKG

Traditional economy class. Not a full flight so spare seats. Food and drinks were good

Was bumped to a later flight because of inefficiency on part of the airline.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Touch screens were very difficult to use, generally being laggy and unresponsive- it was quite an art to get it to play the thing you wanted rather than some thing at random. Selection of films and Tv was good when touchscreen decided to finally respond.

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

4.5 hr international flight. We got a glass of water. Ranks up there with Ryan Air, Easy Jet, Spirit and Frontier. Expected better.

Gluten free options less explicit on business class, but great service

Very good… seems the virgin staff particularly in the lounge and in flight exceeded expectations.

I liked everything about the experience but would have liked some free snacks!

Crew was great but flight was delayed almost three hours due to a technical issue and we had to go back to the terminal and wait for another one.

Being told why we delayed three hours and not even given an apology by someone. Not a word. Not my airline of choice ever.

Checked Baggage line up was long but moved quickly, rest of the process, boarding, crew was excellent

Virgin has always provided a smooth and comfortable flight. This one was no different. Seats are comfortable. Staff are great. This is my favourite airline.

Virgin changed the flight to an Alliance flight. Smaller plane, tea coffee and water the only refreshments available and not sure what happened to the extra money I paid to sit in a selected seat with extra leg room. This is obviously a regular switch as it happened on our flight there and back. Do not recommend.

Late boarding, late departure due to weather and slow boarding, packed 5+hour flight, only 2 toilets for main cabin, tight leg room, no free food except tea, coffee, and water, arrived 75 minutes late.

I had excellent experienced flying with Cebu Pacific on my domestic flight. However, no food and beverage serve might be due to short travel time of 40 minutes.

No entertainment and not expected. Cabin was very cold which brought the comfort score down

Your check in lines were terrible everything else was great!

flight cancelled.. booked through orbitz, yet orbitz won't handle refunds.. never use them again..

It arrived 18 minutes early. Attendant are good. For baording , they should improve especially carrying thru bus.

Super delayed. Delayed to get the bus, delayed to get off the bus, delayed to take off.

exceptionally good with the particular flight because no delay. hope that happens for every flight

Boarding had us in a tunnel with no AC for 15 minutes. Not planned well. And you have to pay for water, get at airport

Kind of worried due to typhoon but yeah we can't do about nature thing. So okay naman kudos to all crews and pilots for the safe landing.

it was good experience though we wait for a minutes in the railday due to no available parking. Keep it up all..

stuck in the aircraft for over three hours due to engineering work, significantly delayed and made a lot of passengers missed the connecting transport, no mention any compensation

Very quiet plane!! One of the quietest planes we have been on.

Jetsatar refused to take my foldable stroller in the plane, despite following all the rules on dimensions and packaging. Similar thing happened on our previous fight. However, at that instance, they offered to check in the stroller. At this fight, the staff was rude, trying to rush us to board the flight. They made excuses that the stroller was not allowed and even offer to leave it behind and ship it back at our own cost. Fortunately, we had someone else attending. Since the flight was about to take off, they left it behind and send it back to us on the next available flight.

Overall, it was good. The only concern was that I couldn't charge my phone because the USB port didn't work after we took off. One of the crew members tried to restart it but never came back to me with an update.

Comfortable seats, boarding was easy and staff were very nice.

Flight was fine but a domestic flight was called by Jetstar international. This meant going through immigration and custom scanning twice. Long queues were experienced which were frustrating. We were using a wheelchair and exit at Perth needed a scissor lift as no air bridge provided. No fast lane at Perth for wheelchair. The staff were helpful but this system is poor.

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.

Not very good, no food and not drink ( caffe or tea). Never ever fly with jet star.

Fabulous I have no issues with JetStar great service always use them to fly

Flight was as expected - we got what we paid for which was a base fare

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

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

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

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

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.

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
