The move follows a campaign against the so-called tampon tax
Glasgow Airport will make available free sanitary products for female passengers.
It follows a campaign by central Scotland Labour MSP Monica Lennon to end period poverty in Scotland.
Lennon has proposed a bill at the Scottish Parliament to ensure free access to sanitary products, including in schools, colleges and universities.
Tampons and pads will be made available in toilets within the main check-in hall and in arrival halls.
Glasgow Airport managing director Amanda McMillan said the firm was happy to support the initiative.
She said: "We met with Monica earlier this year and she highlighted the need to address what is a real issue for many women.
"Millions of passengers travel through our doors on an annual basis and this trial will ensure that our female customers have access to these essential products."
Lennon said: "Providing free sanitary products at the airport sends out a strong message that periods are normal and I know this will be appreciated by passengers.
"No-one should have to go without access to vital sanitary products, so it's great that Glasgow Airport are leading by example on this issue."
In July, the Scottish government announced a six-month pilot project in Aberdeen to provide free sanitary products to women and girls from low-income homes.
