Why you should never drink coffee on a flight

  • Anonymous flight attendant has lifted the lid on what it’s like to work in the air
  • She says that she would never drink the coffee due to the water that’s used
  • She says the water is the same as in the bathroom and can contain bacteria

If you often order a coffee on a flight, then you might want to look away now.

A flight attendant has revealed that the water used for coffee can contain dangerous E.coli bacteria.

‘Betty,’ who says she works for a major American airline, told Vice that the water used for coffee can be the same as the water used in the plane toilets.

An anonymous flight attendant has lifted the lid on what it’s like to work in the air, and advised against ever drinking coffee on a flight due to the water used

The attendant, who wished to remain anonymous to avoid losing her job, warned passengers: ‘Don’t drink the coffee on airplanes.’

Responding to a question about the grossest thing on airplanes after the bathrooms, she told Vice: ‘It’s the same potable [safe to drink] water that goes through the bathroom system.

‘We recently had a test for E. coli in our water and it didn’t pass, and then maintenance came on and hit a couple buttons and it passed. 

‘So, avoid any hot water or tea. Bottled and ice is fine, of course.’

She made the revelations as she lifted the lid on what it’s really like to work in the air.

‘Betty’ is not the first to advise against drinking coffee on a flight.

The Environmental Protection Agency (EPA) discovered in 2012 that when they tested water on commercial airlines, 12 per cent of tested positive for coliform bacteria, which points to other bacteria such as E. coli being present also. 

Travel + Leisure magazine also spoke to a flight attendant for American Airlines, who said the water tanks in planes ‘are probably only cleaned out every six months to a year’. 

In 2016, an AskReddit thread revealed some alarming anecdotes from professed airline employees.

‘The coffee is absolutely disgusting because the no one washes the container that goes out every morning,’ said one. ‘The station agents who get paid way too little don’t give a s*** about cleaning it. I certainly didn’t when I worked for [redacted].

‘Also, because we weren’t given the proper supplies to clean it. We pretty much just rinsed it out and dumped coffee into it,’ the person added. 

There’s another reason why coffee and tea on a flight never tastes as good as on the ground.

The low cabin pressure means that water will boil at 90C rather than 100C, which can result in a poor-tasting brew as teabags are not usually designed for cooler water.
