Five passengers had checked in to fly on the missing Malaysia Airlines flight MH370 but they didn't board the plane.
They had, however, purchased tickets and checked baggage, reports the Star Online, quoting Azharuddin Abdul Rahman, head of Malaysia's Department of Civil Aviation.
Quoting him, it added, Malaysia Airlines had removed those passengers' baggage once it learned they had not boarded the plane, in keeping with standard procedure.
The Southeast Asian country’s online news portal, however, did not give any details of the five passengers.
The Malaysian jetliner has been missing since early hours on Saturday, with 239 people on board.

Sony and Panasonic have today jointly announced a new type of optical disc, which they're dubbing the Archival Disc. As the name of the media would suggest, it's aimed at long-term data storage, both through large capacities and durability.
When Archival Discs become commercially available in 2015, they'll sport 300 GB of storage through triple-layer, double-sided discs. Interestingly, the laser wavelength to read Archival Discs is identical to Blu-rays at 405 nm, although the track pitch has decreased from 320 nm to 225 nm. Sony and Panasonic have implemented crosstalk cancelation technology, making the discs just as readable despite the narrower tracks.
Each disc is not only water and dust resistant, but also able to withstand significant changes in temperature and humidity. Sony and Panasonic say the Archival Disc will have "inter-generational compatibility between different formats", so the data on the discs can be read as the format evolves, but of course this claim remains to be seen.
In the future, the companies are hoping to increase the capacity of Archival Discs from 300 GB up to 500 GB and 1 TB through inter symbol interface cancelation technology and multi-level recording technology respectively. Archival Discs aren't meant to replace Blu-rays, but they will be promoted in the professional space as an "effective solution for protecting valuable data into the future".

Desperate search for plane missing for 12 hours: Boeing 777 with 239 passengers on board mysteriously vanishes over Vietnam
Malaysia Airlines flight MH370 took off from Kuala Lumpur at 12.21am
Vietnamese Navy detected emergency signal 153 miles out to sea
Flight MH370 declared missing nearly 90 minutes after it was due to land
Malaysian Transport Minister said 'no crash site has been found'
227 passengers and 12 crew were from 14 different countries including Malaysia, China, U.S.,
France, Canada, and Australia
France, Canada, and Australia
Two babies, from China and the U.S., are among the missing
Aviation expert Chris Yates said the aircraft will not have been carrying enough fuel to still be flying and 'will have crashed'.
He said the investigation will look at two areas, the maintenance of the aircraft and possible terrorism.
Vietnamese air force spot two oil slicks suspected to be from the wreckage.
A major search and rescue operation is today underway after a Malaysian Airlines plane carrying 227 passengers and 12 crew disappeared off the coast of Vietnam, after losing contact with air traffic controllers.
The Boeing 777 took off from Kuala Lumpur at 12.21am (4.21pm GMT) bound for Beijing, where it was expected to land at 6.30am (10.30pm GMT).
But after reaching 35,000ft and 120 nautical miles off the coast of the Malaysian town of Kota Bharu the plane vanished, prompting fears the aircraft 'could have crashed'.
Aviation expert Chris Yates said the plane would not be carrying enough fuel to still be in the air and would 'definitely have crashed'.
He told Sky News: 'Frankly the plane would not have been carrying enough fuel to stay aloft much longer than an hour after it was due to arrive in Beijing.
'We simply don't know the circumstances behind what caused that crash at the moment.
'There will be two areas for the investigation: the maintenance of the aircraft and also possible terrorism.'
Malaysian Prime Minister Najib Razak said there has been no sign of the missing plane.
He said search operations in an area about midway between Malaysia and Vietnam's southern coast were being intensified.
It comes as the Vietnamese air force reports it has spotted two oil slicks, thought to be from the wreckage of the crash.
Less than one hour after Flight MH370 left Kuala Lumpur for Beijing, the plane disappeared from radar.
Malaysia Airlines CEO Ahmad Jauhari Yahya said there was no indication that the pilots sent a distress signal. The fact that there was apparently no call for help suggests that whatever happened to the flight occurred quickly.
The Malaysian Transport Minister said 14 hours into the search and rescue missions, that no trace of a crash site in the sea has been found, after reports the plane had crashed off the coast of southern Vietnam.
'We are doing everything in our power to locate the plane. We are doing everything we can to ensure every possible angle has been addressed'- Malaysian transport minister Hishamuddin Hussein
'We are doing everything in our power to locate the plane. We are doing everything we can to ensure every possible angle has been addressed,' Transport Minister Hishamuddin Hussein told reporters near the Kuala Lumpur International Airport.
'We are looking for accurate information from the Malaysian military. They are waiting for information from the Vietnamese side,' he said.
Ships in the area have been involved, scouring the vast site for signs of a wreckage.
Malaysian Airlines has confirmed the majority of those on board are from Malaysia and China, with four Americans, two Canadians and seven Australians and passengers from France.
Vietnamese state media, quoting a senior naval official, had reported that the Boeing 777-200ER flight had crashed off south Vietnam, but those reports have been denied, with the plane listed as 'missing'.
The Vietnamese Navy confirmed it detected the aircraft's emergency locator signal 153 miles south of Phu Quoc island in the South China sea.
Admiral Ngo Van Phat told the Vietnamese newspaper Tuoi Tre that radar showed the aircraft had crashed into the sea off the southern tip of Vietnam, close to the border with Cambodia.
The paper later reported the Admiral qualifying his statement, saying the radar had revealed the presumed crash site.
Malaysian naval vessels saw no immediate sign of wreckage when they reached the maritime area off the country's northeast coast this morning, a senior rescue official said.
Malaysia has sent three maritime enforcement ships and a navy vessel to the area, backed by three helicopters, a Malaysian Maritime Enforcement Agency official said.
'Our aircraft asset spotted an orange speck in the sea where the last signal came from. We sent a vessel to search the area and it was confirmed that it was nothing,' he said.
The signal picked up by the Navy is believed to be the Emergency Locator Transmittor, which can be activated manually by the flight crew or automatically upon impact.
Crying relatives of Chinese passengers on board the plane wept at Beijing airport earlier today as it became clear the jet had probably crashed.
An unconfirmed report on a flight tracking website said the aircraft had plunged 650ft and changed course shortly before all contact was lost.
The route would have taken flight MH370, a B777-200 aircraft, across the Malaysian mainland in a north-easterly direction and then across the Gulf of Thailand.
Those on the flight included an American baby and a Chinese baby, and 12 crew members, Malaysian Airlines said in a statement, adding it was working with all authorities in the region and search and rescue teams had been mobilized.
The aircraft had been due to land in Beijing at 6.30am local time but at 7.54am the airline issued a statement saying it had not landed and was officially missing.
On board were 153 Chinese, 38 Malaysians, 12 Indonesians, seven Australians, three French, four Americans, two each from New Zealand, Canada and Ukraine, and one each from Russia, Italy, Taiwan, the Netherlands and Austria.
The pilot of the passenger plane is Captain Zaharie Ahmad Shah, a 53-year-old Malaysia who joined the airline in 1981.
His co-pilot was 27-year-old First Officer Fariq Ab. Hamid, also from Malaysia, who joined the airline in 2007.
If the aircraft has crashed, and all the passengers and crew are killed, it would the deadliest aviation incident since November 2001.
In that incident, 265 people died after an American Airlines Airbus A300 crashed in Belle Harbor, Queens, after leaving JFK Airport in New York. The deaths included five people on the ground.
MAS Operations Control Vice President Fuad Sharuji said: 'We tried to call this aircraft through various means,' adding that it was carrying fuel for 7.5 hours when it disappeared.
Lai Xuan Thanh, director of Vietnam's civil aviation authority, said the plane was over the sea and bound for Vietnamese airspace but air traffic officials in the country were never able to make contact.
The plane 'lost all contact and radar signal one minute before it entered Vietnam's air traffic control,' Lieutenant General Vo Van Tuan, deputy chief of staff of the Vietnamese army, said in a statement issued by the government.
More than 10 hours after last contact, officials from several countries were struggling to locate the plane.
All countries in the possible flight path of the missing aircraft were performing a 'communications and radio search', John Andrews, deputy chief of the Philippines' civil aviation agency, said.
Xinhua said China has sent two maritime rescue ships to the South China Sea to help in the search and rescue efforts.
'It couldn't possibly be in the air because it would have run out of oil by now,' Shukor Yusof, an aviation analyst at S&P Capital IQ, said.
'It's either on the ground somewhere, intact, or possibly it has gone down in the water.'
Aviation experts said that if the report of the aircraft suddenly plunging was correct it could be due to a number of factors.
If it is confirmed that the plane has crashed, the loss would mark the second fatal accident involving a Boeing 777 in less than a year and by far the worst since the jet entered service in 1995.
It would mark the U.S.-built Boeing 777-200ER airliner's deadliest incident since entering service 19 years ago.
An Asiana Airlines Boeing 777-200ER crash-landed in San Francisco in July 2013, killing three passengers and injuring more than 180.
Boeing said it was aware of reports that the Malaysia Airlines plane was missing and was monitoring the situation but had no further comment.
The flight was operating as a China Southern Airlines codeshare.
An official at the Civil Aviation Authority of Vietnam (CAAV) said the plane had failed to check in as scheduled at 5.21pm GMT while it was flying over the sea between Malaysia and Ho Chi Minh city.
These include a catastrophic engine failure; the pilots taking evasive action to avoid another aircraft; or an explosion.
The airline has not said whether the pilots were able to issue a distress call - but if they did not, experts said this could indicate a catastrophy that had occurred without warning.
At Beijing's airport, authorities posted a notice asking relatives and friends of passengers to gather to a hotel about 15km from the airport to wait for further information, and provided a shuttle bus service.
A woman wept on the shuttle bus while saying on a mobile phone: 'They want us to go to the hotel. It cannot be good.'
A waiting area for family and friends was also set up at the Kuala Lumpur airport the flight had left from.
Fuad Sharuji, Malaysian Airlines' vice president of operations control, told CNN that the plane was flying at an altitude of 35,000ft and that the pilots had reported no problem with the aircraft.
The Boeing jet lost contact with Malaysian air traffic controllers a little over two hours into its flight.
Reports from China's Xinhua news agency said later that the aircraft was lost in air space controlled by Vietnam and did not enter Chinese airspace or make any contact with Chinese controllers.
'Our team is currently calling the next of kin of passengers and crew,' the airline's chief executive, Ahmad Jauhari Yahya, said as the airline issued a statement saying its 'thoughts and prayers' were with all those on board as well as their families.
Finding planes that disappear over the ocean can be difficult. Airliner 'black boxes' - the flight data and cockpit voice recorders - are equipped with 'pingers' that emit ultrasonic signals that can be detected underwater.
Under good conditions, the signals can be detected from several hundred miles away, John Goglia, a former member of the U.S. National Transportation Safety Board, said.
If the boxes are trapped inside the wreckage, the sound may not travel as far, he said. If the boxes are in an underwater trench, that also hinders how far the sound can travel. The signals also weaken over time.
Unconfirmed reports said it was believed the missing aircraft was involved in a crash in August 2012 when it damaged the tail of a China Eastern Airlines plane at Shanghai Pudong Airport.
The reports said that in that incident the tip of the wing of the Malaysian Airlines Boeing 777 broke off.
Retired American Airlines captain Jim Tilmon told CNN that 'it doesn't sound very good,' as the search continued for the missing jet.
'The route is mostly overland, which means there would be plenty of radars and radios to contact the plane.
'I've been trying to come up with every scenario that I could just to explain this away, but I haven't been very successful.'
Mr Tilmon said the jet was 'about as sophisticated as any commercial airplane could possibly be.'
Plane's disappearance echos Air France crash
Air France flight 447 crashed over the Atlantic in 2009
216 passengers were killed along with 12 crew members - five Britons were among the dead
Aircraft crashed when pilots lost control when ice crystals affected sensors used to measure the plane's speed
Investigators took two years to find the Air France plane
A leading aviation safety expert has said it is 'extraordinary' that the pilots of a missing Malaysia Airlines plane carrying 239 people did not make a distress call.
The Boeing B777-200 aircraft would have been cruising at about 35,000 feet when it lost contact over the South China Sea, giving the pilots 'plenty of time' to report any technical problems, Flight Global's operations and safety editor David Learmount said.
Mr Learmount said: 'Something happened and the pilots did not tell anyone. Why? It's a good question.
'It's extraordinary the pilots failed to call because they had plenty of time to. Unless there was a bomb on board but there has been no evidence of that.'
Mr Learmount, who is a pilot, drew comparisons with the Air France 447 plane crash over the Atlantic Ocean in 2009, which killed 216 passengers and 12 aircrew, including five Britons.
The aircraft crashed when pilots lost control after ice crystals affected sensors used to measure the plane's speed, he said.
Mr Learmount said: 'This is an historical comparison and could be a coincidence.
'It also happened in the early hours of morning, after midnight in the dead of night, and went missing without a call from the pilots.
'Modern aircrafts are beautifully built and incredibly safe.
'If the engines were to fail because of some kind of interruption to the fuel flow, they can glide with no problems whatsoever for about 40 minutes at that height.'
Mr Learmount said the time which the Malaysia Airlines plane went missing may be significant.
He said: 'Between midnight and 2am you're not at a mental or physical performance high - you're at the lowest performance standard in the 24-hour cycle.'
The failure to locate the plane so far was not unusual, he added, with investigators taking two years to find the missing Air France 447 plane.
However, Mr Learmount admitted he was 'puzzled' why authorities had not divulged a more accurate location of where the aircraft went missing.
'They may not know precisely but they know pretty accurately,' he said.
The 53-year-old Malaysia Airlines pilot, Zaharie Ahmad Shah, has more than 18,000 flying hours and has been flying for the airline since 1981, the company's chief executive Ahmad Jauhari Yahya said.
The first officer, 27-year-old Fariq Hamid, has about 2,800 hours of experience and has flown for the airline since 2007.
BOEING 777: ONE OF THE WORLD'S SAFEST JETS
The Boeing 777 flown by Malaysia Airlines that disappeared over the South China Sea is one of the world's most popular - and safest - jets.
The long-range jumbo jet has helped connect cities at the far ends of the globe, with flights as long as 16 hours.
But more impressive is its safety record: The first fatal crash in its 19-year history only came last July when an Asiana Airlines jet landed short of the runway in San Francisco. Three of the 307 people aboard died.
Airlines like the plane because it is capable of flying extremely long distances thanks to two giant engines.
Each engine is so massive that a row of at least five coach seats could fit inside it. By having just two engines, the plane burns through less fuel than four-engine jets, like the Boeing 747, which it has essentially replaced.
"It has provided a new standard in both efficiency and safety," said Richard Aboulafia, an aviation consultant with the Teal Group.
"The 777 has enjoyed one of the safest records of any jetliner built."
Besides last year's Asiana crash, the only other serious incident with the 777 came in January 2008 when a British Airways jet landed about 1,000 feet short of the runway at London's Heathrow Airport.
Malaysia Airlines did have an incident in August 2005 with a 777 flying from Perth, Australia, to Kuala Lumpur, Malaysia's largest city.
While flying 38,000 feet above the Indian Ocean, the plane's software incorrectly measured speed and acceleration, causing the plane to suddenly shoot up 3,000 feet.
The pilot disengaged the autopilot and descended and landed safely back in Perth. A software update was quickly made on planes around the world.
Malaysia Airlines has 15 Boeing 777-200ER jets in its fleet of about 100 planes. The first was delivered on April 23, 1997, and the most recent on December 13, 2004, according to Boeing. The 200ER is one of four versions of the 777.
The 777 is capable of flying 7,250 miles non-stop. Its two Rolls-Royce Trent 875 engines each have 74,600lb of thrust, letting the plane cruise at Mach 0.84, or nearly 640 mph.
A new model has a list price of 261.5 million US dollars (£156 million), although airlines usually negotiate discounts.
The 777 was the first twin-engine plane to be immediately certified to fly over the ocean as far as 180 minutes from any emergency landing airport.
Government safety regulators have determined that it could fly for nearly three hours on a single engine in the case of an emergency.
