Jetstar passengers 'freak out' over cabin phenomenon: 'Never seen anything like it'
Passengers on a recent Jetstar flight from Bali to Australia were completely baffled when boarding the plane, as the cabin appeared to fill with what looked like thick smoke. Those on the plane could barely see in front of them when they searched for their seats as the phenomenon unfolded. One Aussie on board said "I've never seen it that bad".
Theories began to fly online as Aussies attempted to understand what was going on after a passenger shared a video. One respondent admitted the scene left her feeling "freaked out".
Some speculated that the smoke came from a fire, while others believed it to be antibacterial spray. A third thought it was simply condensation caused by humidity.
However, Jetstar told Yahoo "customers shouldn't be concerned" by the sight, explaining exactly what's going on.
"My Jetstar flight was like this from [Bali] to Sydney last weekend, I've never seen anything like it," one said, admitting they "thought something was wrong with the plane".
The traveller who took the vision told viewers he believed there was a simple explanation for the issue.
"I think with the humidity in Bali and the air on the plane, it just fogged up way more than it should've," he said.
It's not the first time travellers have been concerned by such a sight — with a similar scenario taking place last year.
Jetstar confirmed that the phenomenon happens when "warm and humid air mixes with cooler and drier air from the aircraft air-conditioning system, forming condensation.
'Customers shouldn't be concerned as it's a common occurrence in hot and muggy environments like Bali and usually clears quickly," the spokesperson said.

Professor Martin Singh from Monash University previously told Yahoo News Australia the smoky air is caused by the cool air conditioning inside the plane interacting with high levels of humidity outside.
"When the hot moist air from outside mixes with the cool air in the plane, it causes condensation," he explained. "This is the same process that causes you to be able to see your breath when it is particularly cold out."
He explained "key physics" is taking place, saying the amount of water vapour present in the air is "much higher at a higher temperature".
"When moist air cools down, it becomes 'saturated' with water vapour, and any further cooling results in condensation," he said.
Passengers travelling to humid destinations in Australia like Cairns and Darwin can also expect to see the mist.
