An Indonesian man, whose wife is a passenger onboard the missing AirAsia flight QZ8501, makes a phone call at a waiting area in Juanda International Airport, Surabaya. – Reuters pic, December 29, 2014. The disappearance of an AirAsia flight marks a tragic climax to a heartbreaking 2014 for Malaysians still grieving from the loss of two planes operated by their national carrier, and has some wondering whether their country is cursed.

Nine months after Malaysia Airlines flight MH370 disappeared, followed by the shooting down of MH17, the latest disappearance is the third crisis for a Malaysian airline this year.

The AirAsia plane, carrying 162 people, disappeared in bad weather Sunday while flying to Singapore from Indonesia, losing contact with air traffic control in a chilling echo of the earlier tragedies.

"Why is this country facing such hardships? It is painful when disaster strikes without warning. Is it a curse? I think we are fated," Subramaniam Gurusamy, whose son Puspanathan Subramaniam was one of 239 people on board MH370, told AFP.

With the painful memory of two plane disasters this year still fresh, the news left many in Malaysia bewildered during the traditional year-end festive season.

Social media users immediately offered prayers and messages of support to family members of the victims via Facebook and Twitter, and urged the carrier's flamboyant chief executive Tan Sri Tony Fernandes to remain strong.

"I personally pray for all the passengers and crews of AirAsia Airbus A320 QZ8501. Especially my cousin Oscar Desano as a flight attendant," said Twitter user Paris Duarte.

QZ8501's disappearance came as Malaysia grapples with its worst floods in decades, which have displaced more than 200,000 people, piling further anguish on the country.

"God pls help my country Flood tornando MH370 lost MH17 shot down QZ8501 still lost contact hoping and praying," Angah Kalisa said on Facebook.

Uthaya Kumar Pillai referenced Malaysia's diversity when he wrote on the social networking website: "My support for SAR (search and rescue) team. Let us unite together and pray for 8501 regardless of race."

Churches nationwide lit candles, praying for the plane, which is operated by AirAsia Indonesia, a subsidiary of the low-cost Malaysian regional giant, to be recovered and for the safe return of all its passengers and crew.

"Our hearts go out to all the families who in anguish are awaiting news of the whereabouts of the plane," The Council of Churches Malaysia wrote on its Facebook page.

"In the meantime churches throughout the country will join all other Malaysians in lighting of candles and praying for the families."

Tan Sri Harussani Zakaria, the mufti of northern Perak state, attributed the air tragedy and floods to domestic political bickering.

"Due to this incessant political fighting, we are being tested by Allah," he told AFP.

"Such incidents are a test from Allah. We should unite and strive for peace among races. I pray for the families and hope all will return home safely."

Malaysian Prime Minister Datuk Seri Najib Razak took to Twitter to express his solidarity: "Called (Indonesian) President Joko Widodo. Expressed our deep concern. Offered M'sia's fullest support & assistance to Indonesian search & rescue effort."

National carrier Malaysia Airlines, itself still reeling from the loss of its two planes, wrote: "#staystrong @AirAsia – Our thoughts and prayers are with all family and friends of those on board QZ8501."

Fernandes chimed in on Twitter, writing: "My only thought are with the passangers and my crew." 

"We put our hope in the SAR operation," he said.

Fernandes later added: "Keeping positive and staying strong. My heart bleeds for all the relatives of my crew and our passangers. Nothing is more important to us."

AirAsia changed its fiery red logos on its Facebook and Twitter accounts to a sober gray following the incident.

The Airbus A320-200 lost contact around an hour after it left Juanda international airport at Surabaya in east Java at 2235 GMT Saturday (6am Malaysian time).
