Airline passenger shares tip for bringing reusable water bottles on the plane: 'Did you know?'

"So you probably know you can't bring liquids onto a plane, but did you know you can bring ice?"

Reusable water bottle

With tight security restrictions and exorbitant beverage prices, it can feel impossible to find an affordable drink at the airport. 

Most Americans already don't drink the amount of water that health experts recommend, and air travel further dehydrates passengers due to the low humidity levels in airplane cabins. This means that staying hydrated is especially important when traveling by air.

An Instagram user named Krys (@krystalynngier) is going viral thanks to her simple, sustainable solution to this problem. In a recent post, she shared her tip for always having ice cold water on plane trips.

"So you probably know you can't bring liquids onto a plane," Krys says in the video. "But did you know you can bring ice?" 

This fact might sound counterintuitive, but it's true. The TSA's website specifies that frozen liquids are always allowed through security checkpoints as long as there's no melted liquid in the container.

"So I filled up my reusable water bottle with ice. I got through security and asked a little coffee shop on the other side to fill it with filtered water," Krys explains. 

Most airports also have drinking fountains or water bottle-filling stations that you can use. It's a simple trick that significantly reduces the waste you generate as a passenger.

Waste is a significant problem in the world of air travel. Airlines produced 6.7 million tons of trash in airplane cabins in 2018, and some individual airports, like the San Francisco International Airport, cycle through 4 million plastic water bottles per year. 

Airlines like Iberia are attempting to curb their plastic waste by introducing sustainability programs. Some airports — such as those in India and San Francisco — have banned single-use plastic water bottles altogether. 

The best way to reduce your carbon footprint is to avoid purchasing plastic products whenever possible. And one of the easiest ways to do that is by investing in a reusable water bottle that you can refill and wash at home. By using a reusable water bottle, you could avoid sending 156 plastic bottles to landfill each year.
