Two Estonian siblings were arrested and fined at Suvarnabhumi International Airport today after they were found smoking on a flight, despite cabin crew telling them that it is illegal.

Meanwhile, Thai police are trying to locate a woman who was caught on camera vaping during a flight from Mae Fah Luang airport.

After the airline touched down in Bangkok, the Finnair crew reported to Suvarnabhumi Airport officials that the two siblings had smoked in the aircraft’s bathroom during the flight to Bangkok.

The cabin crew told them to stop, but they smoked again on five separate occasions. Consequently, they were each fined 20,000 Baht.

In a separate case, a viral video shows a woman smoking e-cigarettes during the flight. The nationality of the woman in question is not yet known.

Somchanok Tiamtiabrat, director of Mae Fah Luang International Airport, stated that the passenger and baggage search process usually identifies hazardous items in airports adding, though, that some e-cigarettes are made of plastic, which could be missed.

According to the Tobacco Product Control Act 2017, smoking on planes is prohibited and offenders face imprisonment not exceeding one year and/or a fine not exceeding 40,000 baht on conviction.

After the video went viral, netizens questioned how the airport authorities had allowed these e-cigarettes to pass through to the aircraft.
