Very pleased. Very professional and organized. Very clean aircraft. Efficient boarding and even a snack.

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 .

The planes are getting quite old, the staff are quite ok good ok thanks Garuda

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Good, ontime performance...hard products is somewhat out of date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