As in Britney's original chart-topper, 2003's "Toxic", Assraf dances down the aisles, sings into the intercom and pushes a food trolley down the Airbus 330's cabin - all in flawless precision - mimicking Britney's very own dance moves for the hit.
The entertaining video garnered a lot of buzz across social media, as it managed to gather over 4,000 retweets and likes on Twitter and over 200,000 views on Instagram - so much so that it was even picked up by 9gag!
SUN, SEA AND THE SPHINX Is it safe to travel to Egypt?
A copy of the video was shared on Facebook by Liam Dineen on Sunday, and has since clocked more than 120,000 shares.
"Booking my flights on AirAsia now", said one Facebook user.
Another user called Itsnighthunt said: "This is wonderful, adore it!"
'The talent in Airasia never fails to amaze me.
Some people have speculated that the flight attendant could lose his job after the video surfaced.
But the CEO of AirAsia was so impressed with the clip that he reposted it on his own Instagram page. "Classic. AirAsia version of Toxic. Love it that staff can just have fun and be themselves", read the caption.
