The departure hall at about 11am, its peak period, looked its normal self - packed with travellers - but all flights were operating as usual.
"If there are a lot of cancelled flights, the situation would be more chaotic. This is considered fine.
"Now it seems everything is back to normal and this is a usual scene of the departure hall as now is the peak hour," said an airport ground staff.
Although there were several flight delays on Tuesday, a statement issued by AirAsia said that it was due to operational requirements.
"AirAsia is working towards a resolution to ensure all guests enjoy a smooth journey.
"All affected guests are being informed accordingly and necessary assistance is being provided.
"AirAsia sincerely apologise for the inconveniences caused," it said on Wednesday.
Among the flights that were delayed were to Kota Baru, Tawau, Don Mueang and Chiangmai in Thailand and Jakarta, Indonesia.
Hundreds of passengers were left stranded at the low-cost terminal after AirAsia pilots reported sick on Tuesday.
Some flights were cancelled, others delayed forcing the passengers to spend the night at the airport.
AirAsia CEO Tan Sri Tony Fernandes confirmed the situation when he tweeted "unfortunately had 13 pilots sick which caused flight issues."
The flights schedule became chaotic after flights were re-timed. Some passengers were told that their flights were moved to other flights but were later cancelled.
