The American pop star plays a flight attendant in the video, directed by award-winning music video director Joseph Kahn.
Real-life flight attendants might be more used to serving hard passengers than working as undercover spies - as Spears does in the video - but when the passengers are gone, it's another story.
"Not only that they are excited about Britney landing in Bangkok and love the song Toxic, but they also had a lot of fun representing our brand". Thankfully, Nok Air executives loved it.
As Britney Spears prepares for Friday evening's concert - the first of two at Bangkok's Impact Arena - three parodies of her "Toxic" video, which featured the multi-platinum recording artist as an air stewardess, have themselves become worldwide hits.
Assraf Nasir, a crew member for AirAsia acted out a similar rendition of the dance moves in March.
The video went viral and is still doing the rounds on social media.
"Classic. AirAsia version of Toxic". "The talent in Airasia never fails to amaze me", he posted on Instagram.
This wasn't just a video created for fun, either.
