A room temperature drink might be better.

Studies testing the cleanliness of both ice and water onboard flights might concern you.

Why Shouldn’t You Have Ice on a Flight?

The ice is put in a tray with a scoop, and the trays dont get cleaned very often.

Every surface on the plane is touched by hundreds of people daily and not often disinfected.

We dont have the opportunity to wash our hands at all during the beverage service.

Of course, its not clean because this is how much [time] they give us.

According to Montalvo, both time constraints and labor shortages have contributed to a lack of airplane cleanliness.

In fact, Montalvo stated her crew often has under five minutes to both clean and inspect planes.

Shes even been tasked with cleaning an entire plane by herself.

We need time and more people, Montalvo added.

You should forget about the onboard water on planes too.

A score of 3 or better indicated an airlines onboard water was relatively safe.

As the findings showed, seven out of the 10 major airlines analyzed scored under a 3.

Only Allegiant and Alaska (3.3 each) and Hawaiian Airlines (3.1) scored above the threshold.

My takeaway from doing the research was to not drink the coffee and the tea.
