Jetstar Flight Cabin Fills With Condensation Fog Before Takeoff

A Jetstar flight from Bali’s Denpasar Airport to Melbourne filled with thick condensation fog before takeoff, according to video posted on TikTok. The fog became so dense that passengers could see only about two or three rows ahead while the aircraft remained on the tarmac at Denpasar.

TikTok user Giselle posted footage showing travelers adjusting their overhead air vents in an attempt to disperse the haze. In a caption on the video, she wrote that the plane’s air conditioning appeared to be working overtime. She noted in a voiceover that condensation can occur when there is a large temperature difference between the cabin and outside air.

Giselle told Yahoo Lifestyle the haze was visible from the moment passengers boarded but grew progressively thicker. ” Cabin crew addressed the situation by making several announcements that the mist came from the cooling system and posed no danger.

Comments on the video included both expressions of alarm and statements that the phenomenon is normal. One commenter wrote they would have left the aircraft, while another noted it occurs frequently in tropical areas. A third person said a similar event had happened to them departing from a tropical airport and that it had been startling.

Some viewers compared the scene to a nightclub or haunted house. Others pointed out they had experienced milder fog on planes but never to this extent. One commenter with 30 years of frequent flying said they had never seen fog this thick inside a cabin.

The fog results from sharp differences in temperature and humidity, particularly when hot, humid outside air meets cold air from the aircraft’s air conditioning system while the plane is stationary. The mist typically clears once the aircraft begins moving or the cabin temperature stabilizes.
