Flight attendants are advising passengers to skip coffee and tea on flights due to concerns about the cleanliness of onboard water supplies. These beverages are often prepared using water from tanks shared with toilets and sinks that are not cleaned frequently enough.
Why it matters
The warning stems from water safety tests revealing that most airlines fail to meet basic hygiene thresholds. Many passengers remain unaware that the same water used for hand washing is also used for their hot drinks.
A water safety study evaluated 11 major and 12 regional airlines on a five-point scale. Only three airlines achieved a score of three or higher, which is the benchmark for relatively clean water.
The details
Coffee machines and water tanks on aircraft are reportedly rarely cleaned, leading to potential contamination risks. Consequently, some carriers have opted to eliminate snack and drink services entirely to avoid these sanitation challenges.

Culture Shift
This report follows a pattern set by the airline water safety testing standards, which have historically spotlighted the gap between passenger expectations and operational hygiene. It reflects a growing consumer movement toward greater transparency regarding the health standards of travel services.
Travelers may want to opt for bottled water or other sealed beverages during flights to avoid potential water tank contamination. Adopting this habit can help passengers bypass the sanitation risks associated with aircraft-prepared coffee and tea.
The takeaway
Passengers should prioritize consuming sealed, pre-bottled drinks whenever possible to ensure sanitary conditions while traveling. Staying informed about airline hygiene practices allows for better decision-making during long-haul or regional flights.
