Normally, it's 2 hours before departure. We have our E-ticket and Air Asia lets us check-in on-line up to 14 days before departure. since our flight is at 6:45AM, are we pushing it to arrive 1 1/2 hours before departure? We have no checked baggage.

From airasia website ................

"For flight numbers beginning with AK, FD, PQ & QZ, you must be at the boarding gate at least 30 minutes prior to schedule departure.

For flight number beginning with D7, you must be at the gate at least 90 minutes prior to time of departure.

Please note that our gates close 20 minutes prior to time of departure. You will be denied boarding if you fail to be at the gate 20 minutes prior to time of departure."

You should make it without too many dramas.

Print your boarding pass at the kiosk in departures and go straight to the Immigration doorway.

Went through there 2 weeks ago (6.15 AM Flight) and it was not that busy.
