Why You Might Want to Skip Coffee on Long Flights

Ah, the allure of a hot cup of coffee at 35,000 feet—tempting, isn’t it? Especially when you’re trying to stay awake through the latest in-flight movie or need a pick-me-up after navigating airport security. But before you flag down the flight attendant, here’s why you may want to skip that cup of coffee on long haul flights.

The Not-So-Fresh Truth About In-Flight Coffee

Water Tanks: A Hidden Culprit

The water used for brewing coffee on planes comes from onboard tanks that, according to some flight attendants, aren’t cleaned as regularly as you’d hope. In fact, a former flight attendant mentioned that these tanks are “rarely cleaned unless they are broken.” That doesn’t exactly inspire confidence, does it?

And here’s the kicker: if you do pick up a mild bacterial bug, you probably won’t feel the effects until you’re a few days into your trip—by which time you’re blaming the resort breakfast, the street food, or the poor hotel manager who served you prawns with a side of regret.

Speaking from personal experience, I’ve had my fair share of Delhi belly in the first 72 hours of a trip. But since I stopped drinking tea and coffee on flights? Not a single incident. Coincidence? Perhaps… but I’m not risking it.

Proximity to Lavatories

Adding to the ick factor, these water tanks are often located near the aircraft’s lavatories. While there’s no direct evidence of contamination, the mere thought is enough to make some passengers opt for bottled beverages instead.

Caffeine and Dehydration

Long flights already pose a risk of dehydration due to the dry cabin air. Caffeine, being a diuretic, can exacerbate this issue, leading to increased trips to the restroom and potential discomfort, especially for us travellers over 50.

Opt for Bottled Beverages

Stick to bottled water or canned drinks. They’re sealed, reducing the risk of contamination, and help maintain hydration levels during your flight.
