The movie star's drinking water company Mananalu - which he founded in 2019 - recently partnered with Hawaiian Airlines.
The publicity stunt was to promote the company's new recyclable aluminium bottles, which the carrier was using to replace plastic onboard.
Since April the airline has been using the 500ml bottle across premium cabin classes flying long-haul.
"We couldn't be more thrilled to partner with Hawaiian Airlines. Together we're reducing single-use plastic bottles on flights and removing plastic from our oceans. It's perfect brand alignment," David Cuthbert, CEO of Mananalu, said earlier this year.
