Passengers travelling through Glasgow, Southampton and Aberdeen airports will be asked to bring their own face masks as key routes are relaunched this month.
Staff at the three airports have been provided with personal protective equipment (PPE), including face masks.
Structural changes have also been made to the buildings to combat the spread of Covid-19.
Protective screens have been installed and hand sanitiser dispensers placed throughout the AGS airports. Surfaces will be cleaned with electrostatic fogging machines which disinfect within two minutes.
Touch points and security trays will be treated with an antimicrobial product that kills germs, lasts for up to 30 days, and has been tested as effective against Covid-19.
Floor markers are also in place to aid social distancing and anyone with coronavirus symptoms is being asked not to travel to the airports.
Domestic routes will be relaunched at Glasgow and Aberdeen airports throughout this month to cities in England and Northern Ireland and to Stavanger in Norway.
Derek Provan, chief executive of AGS Airports, said: “Our airports have remained open throughout this pandemic to provide crucial lifeline services.
“During this time, we’ve worked closely with both the UK and Scottish governments, and their officials, to ensure we follow all health guidance.
“As the lockdown begins to ease and airlines start to confirm plans to restart domestic connectivity, it’s important we do everything we possibly can to keep our airports clean and safe for our staff and for our passengers.”
