Former flight attendants have cautioned air travelers to be more mindful of what they eat and drink during flights, warning that some in-flight options may pose health risks.
Alex Quigley, who spoke in an interview with Women’s Health, revealed that hot beverages such as coffee and tea are among the riskiest choices due to questionable water storage practices on aircraft.
“Aeroplanes utilise potable water tanks, and often, that water sits there for a long time. There’s no telling how often or when the tank has been cleaned last,” Quigley said.
He added that leftover coffee is often disposed of in plane toilets, with little evidence of tanks being regularly washed.
Beyond hot drinks, Quigley cautioned against meat-based meals, noting that long delays and improper storage can compromise food safety, raising the risk of food poisoning.
He also advised passengers to avoid strong-smelling snacks, such as barbecue-flavoured corn nuts, which can become unpleasant in pressurised cabins.
Equally concerning is alcohol consumption midair.
Quigley explained that high altitude reduces the body’s ability to absorb oxygen, leaving passengers more dehydrated and light-headed.
Another flight attendant added that acidic or salty drinks like Bloody Marys and orange juice could be particularly harsh.
Experts also warned that foods consumed before boarding, especially beans, dairy, sodas, or fatty meals, may lead to bloating and discomfort once in the air.
