Good value for money. Food was below expectations but acceptable.

Check in was seamless, and easy, with friendly understanding staff and helpful Flight took off early - was good experience Meal was sub standard with only 4 pieces of chicken and container full of rice

We were upgraded to better seats. No entertainment. Food mediocre

Flight was half an hour delayed and gate was changed only once but not very far. Weather was good so smooth flight. So all in all was a good flight on a Sunday.

Boarding was on time and orderly. Crew was efficient. Departure as scheduled. I did not order food.

The overall flight was okay. Aircraft was a bit run down like the toilets, seat and table. The worse was checking in and boarding. They had no priority for people with children (young infants and babies included) even when we requested. Unhelpful staff.

Flight was booked with a hacked credit card and flyer was allowed to board despite airline being advised. Shameful behaviour.

I did not book or take this flight. This was a fraudulent credit card purchase using my (now cancelled) card. Air Asia was advised that this was a fraudulent booking a week before the flight. If this service was allowed AirAsia is contributing to credit fraud. If they didn’t take that seriously how serious are they about protecting your details?

Due to very heavy rain in Jakarta which caused bad floods on the highways the captain kindly delayed the departure to allow many passengers to reach the plane with almost 2 hours delay. Otherwise the flight was smooth and uneventful. I was disappointed that given the long delays the passengers were not even treated to a free bottle of water. I had to buy a packet of salted peanuts and bottle of water since I missed lunch.

They don t offer even a glass of water need to buy a drink if you are tursty they can save money and timeby cancel the food offer for 1 hr fly both fly nobody buy and try sale on boad thinkthe we can buyduty free store
