by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask

Great as usual, some delays but well communicated and made up for in the air

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Overall experience was good but what really impressed me the most was the care the flight attendants took of a sick passenger who was sitting in front of me. The flight attendants would come and check on her quite regularly providing her support and comfort. Brilliant service!

Only answered OK and poor as there was no entertainment and I didnt have any food

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.

We were allowed to board early, seats were spacious and we arrived early.

The seats were dirty. Food on tray table. Late on my first flight and almost an hour early on the return. My driver was unable to adjust and I had to pay for different ground transportation.

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

Flight was delayed more than 1.5 hours. Gate changed multiple times

The good thing is that the flight got us from Darwin to Brisbane. However, it would have to be the most uncomfortable flight I have ever taken and if I can possibly avoid flying Jetstar again, I will.

I was treated poorly in Dunedin by check in crew, then my bag was lost in Auckland. Never again.

no announcement about why we where delayed which is very poor

It was better than I expected. Thought $5 for a small cup of tea was a bit much!

Overall good trip I find seats a bit hard. We were waiting on board for about an hour for 2 passengers with some document issue. This main our arrival late for our pickup person.

15kg allowance is outrageous. Change of time a few days before departure and more than 2 hours of delay in the end. The worse we’ve taken so far in Oceania.

They added the weight of my back to the carryon luggage and charged me NZ$75 for being over 7 kg.

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.

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

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.
