A British tourist and his wife lost their luggage when they put it through an x-ray scanner at the 'world's worst airport'.

Daniel Lynch and wife Abigael were going through security checks when the sling bag allegedly mysteriously vanished at the Ninoy Aquino International Airport in Manila, the Philippines, on March 2.

The couple said they put their belongings through the machine as they prepared to leave for London, UK, but one of the bags, which contained a phone, wallet, and some IDs, did not come out the other side.

Footage shows the airport officers searching around the machine while the distressed Filipina wife was heard speaking to them.

Abigael said: ‘We have so many bags, we haven't even finished yet and one has already gone missing.'

Manila International Airport Authority Executive Assistant Attorney Chris Bendijo told local media they have started investigating the incident.

He said: ‘When the victims entered, there was a group of about four to six individuals that followed them.

‘In the X-ray area, we found four suspicious people, two males and two females, who hounded the British national, and we believe one of them took the bag.'

The official also clarified that none of the suspects worked for the airport, nor were they passengers.

The bag remained missing while the couple boarded their flight to London later that day.

American luggage app Bounce listed the state-run Ninoy Aquino International Airport as the world's worst airport for business class travellers in 2022. It ranked bottom 38th out of 38 busy airports all over the world.

This year, it was ranked '4th worst airport in Asia' for business travellers by UK website businessfinancing.co.uk, citing passenger reviews for international airports from airlinequality.com.

In September last year, an airport screener was caught on camera allegedly swallowing a wad of stolen cash from a tourist worth 300 USD.

In 2013, a high-profile extortion racket called 'drop bullet' was uncovered, where airport personnel allegedly planted bullets in luggage to extort passengers.

Earlier this month, horrified passengers found bed bugs on the benches and rats scurrying across the ceiling in the departure lounge.
