Tea Expert Reveals Why to Skip Hot Drinks When Flying

Many travelers look forward to enjoying a hot cup of tea or coffee while soaring at 30,000 feet, finding the offer comforting and cozy. However, according to tea expert Arthur Gautier from Nio Teas, there are compelling reasons to reconsider this travel tradition, and they extend beyond concerns about caffeine.

The water tanks don’t get cleaned as often as you’d think

Unless you’re traveling with an airline that boasts advanced cleaning technology, those onboard water tanks are not routinely sanitized between flights. Gautier emphasizes that the water used for tea and coffee typically comes from large tanks that may go for days or longer without being properly cleaned. “It’s not always as clean as you might think,” he notes, particularly on long-haul flights with tight schedules for maintenance.

A 2019 study by the EPA found that several airlines did not meet federal safety standards for their water systems. This finding may confirm the suspicions of many travelers.

That machine is right next to the lavatory

Most coffee machines on flights are situated close to the bathrooms. This proximity can be concerning, especially since Gautier mentions that these machines are often cleaned only when they malfunction. Thus, what you might be sipping could contain more than just oversteeped Earl Grey.

If you still want something warm, bring your own setup

Should you still crave the comfort of a warm beverage, especially on long journeys, Gautier suggests a practical alternative. Request a cup of hot water, but have your own water bottle at the ready. Use the hot water to warm your bottle or to steep your tea directly if you feel comfortable doing so. Opt for teas that steep well at lower temperatures, such as green, white, or herbal blends like chamomile or peppermint. “It’s not the easiest setup,” he admits, “but it’s cleaner, and you still get that comforting ritual.”

If you decide to go this route, steer clear of black teas or oolongs that require boiling water to fully develop their flavors, as the lukewarm water provided mid-flight won’t do them justice.

Your tea won’t taste right at altitude anyway

Even in the best circumstances, your cup of tea will not have the same taste in the air. The pressure in the cabin diminishes your sense of taste, particularly for sweet and salty flavors. “At altitude, your sense of taste drops,” Gautier explains, “so your favorite tea might taste flat or muted, irrespective of how skillfully you brew it.”

For tea enthusiasts or those seeking a caffeine fix with their in-flight snacks, now might be the time to explore a new option. For those sensitive about water quality, it’s best to stick with sealed bottles and bypass the mystery brew altogether.
