Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

It was with Link Airways and the Saab 340 jet was noisy and little comfort.

They didn’t sent my luggage I got it 24 hours later

Plane was late and they wouldn’t check our bags through to Tokyo

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!

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

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

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.

Jet star delayed both trips with poor communication. Passengers were made to change gates often and then left to stand with no seating. As someone getting over surgery this was very trying.

Delayed twice. Poor communication and people made to change gates too often.

Very disappointed with my recent Jetstar experience. Firstly, it was extremely frustrating that we had to pay extra for basic things like in-flight entertainment and meals. Other airlines provide these essentials even with standard tickets, but Jetstar offered no comfort or amenities without additional charges. For a long international journey, this made the experience very uncomfortable. On top of that, there was a delay on our flight from Melbourne to Bangkok due to parts replacement, which was already inconvenient. But the biggest issue was the massive 5 hours and 15 minutes delay on our return flight, which completely disrupted our plans, caused unnecessary stress, and impacted both our time and health. Jetstar provided vouchers, but they were not nearly sufficient to cover proper meals or any meaningful service at Bangkok Airport. After such a long delay, this felt extremely inadequate and did not compensate for the inconvenience we faced. Overall, this has been one of my worst travel experiences. I am extremely disappointed and will not be booking with Jetstar in the future. I strongly request Jetstar to provide additional compensation for the significant delays and the discomfort we had to go through.

Excellent help with Wife needing disability access at Brisbane airport

The flight was delayed by 2 hours but the Jetstar crew were fantastic.

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

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