Which airports are banning plastic water bottles?

The prohibition makes LAX the second airport in the world to prohibit the use of plastic water bottles, following San Francisco International Airport (SFO) in 2019. In 2021, SFO extended the plastic ban to all types of beverages.



Several major airports have led the charge in banning the sale of single-use plastic water bottles to meet 2026 sustainability goals. San Francisco International (SFO) was the pioneer, followed by Los Angeles International (LAX) and London City Airport. In 2026, many other hubs like Madrid-Barajas and Amsterdam Schiphol have implemented similar bans or high taxes on plastic containers. These airports encourage travelers to bring their own reusable bottles, providing "Hydration Stations" or high-tech water refill kiosks throughout the terminals. This shift is part of a broader "Green Aviation" initiative aimed at reducing the millions of tons of plastic waste generated by travelers every year. It is a high-value strategy for any traveler in 2026 to carry an empty reusable bottle through security; not only does it help the environment, but it also saves you from paying the "premium" $5 to $7 price for a boxed or glass-bottled water inside the departures lounge.
