Airasia

Received a sms from airasia saying the flight to hong kong has been reschedule from 720am to 630 am. earlier i saw and advert by airasia saying for any delay of 2 hours they would give rm200 voucher.... have not read the fine print yet... so what about rescheduling?

I wonder what time do i have to leave home? two hours before check in means by 430 am at LCCT... 330 am?? man....
