AirAsia is a Malaysia-based airline that is popular in the region as a budget carrier. It has about 100 destinations, with affiliate companies in several Asian countries.

The missing plane is operated by AirAsia's Indonesian affiliate, in which the Malaysian company holds a 48.9% stake, according to its website.

AirAsia has a "very good" reputation for safety, CNN aviation correspondent Richard Quest said.

Flight 8501's captain has a total of 6,100 flying hours, and the first officer a total of 2,275 flying hours, the airline said. The plane's last scheduled maintenance was on November 16, it said.

10:40 pm

Flight 8501 "was requesting deviation due to en route weather before communication with the aircraft was lost," the airline said.

The flight's captain asked permission to climb to a higher altitude, Murdjatmojo said, according to the national news agency.

According to flight tracking websites, almost the entire flight path of the plane was over the sea.

Bad weather gripped the region at the time, CNN meteorologist Derek Van Dam said.

"We still had lines of very heavy thunderstorms" when the plane was flying, Van Dam said. "But keep in mind, turbulence doesn't necessarily bring down airplanes."

CNN aviation analyst Mary Schiavo said that if there was an onboard emergency, the pilots should have issued a mayday call or a pan-pan call.
