Airline reviews

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

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.

no announcement about why we where delayed which is very poor
