Would not fly again. Everything is sub par. Honestly not worth the price we paid. Would have rather flown Jetstar and saved the money.

Would not fly again. Everything is sub par. Honestly not worth the price we paid. Would have rather flown Jetstar and saved the money.

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

Entertainment was poor at best. Very old movies and tv show and not really good ones .

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Good, ontime performance...hard products is somewhat out of date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

On air services are excellent. The Garuda Lounge at Terminal 3 Soekarno-Hatta International Airport need to have special management attention in cleanliness and the service quality.

At CGK, need to walk from one gate all the way to the other gate to board the plane. Which makes me wonder, why can’t we just gather at the correct gate in the first place?

There were no food or entertainment on this short flight. Friendly staff even before getting on the flight. The seats were snug but it was quick flight

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

Flight was late, food and drink an extra charge, my carry on is five rows behind me, and the seats are too narrow. Don’t ask me to be happy about it

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

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

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.

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.

Check-in was good and efficient, Boarding was quick and easy. Didn't like the entertainment side of things requiring your phone to connect for a screen, my eyes are bad enough to use my phone more than I already do. Trip was comfortable and baggage claim was good. If coffee and tea were free, then why not a soda or juice as well, its not like its an alcoholic drink.

The flight was delayed by 45 minutes, but boarding, actual flight, and crew were great. However, there was Zero free food and only water, tea, or coffee to drink. Everything else was for sale. No onboard entertainment but it was a short flight.

I'll never transit from international through Sydney with Virgin until they improve the domestic transfer system. It's ridiculous that you have to take oversize baggage to the transfer desk to get it activated then struggle onto the shuttle bus (carrying a 25kg, 2m long ski bag and carry-on - along with about 6 others in the same situation) then negotiate the terminal and queue to put it onto the oversize receival bag drop.
