Staff working at Aberdeen, Glasgow and Southampton airports will be provided with personal protective equipment (PPE), including face masks.
Protective screens have been installed in key areas, including the check-in and security halls.
Passengers will be asked to come prepared with their own facial coverings and will have to observe physical distancing wherever possible.
The health measures are being introduced along with hygiene enhancements by owner AGS Airports as a number of airlines prepare to resume domestic flights later this month.
AGS has also enhanced its “already-thorough cleaning regimes” with a specific focus on hard surfaces, which will be regularly disinfected as part of the additional health measures.
At Glasgow, routes being introduced include easyJet to Belfast International and Gatwick, and Loganair to Southampton on June 15.
Aberdeen will gain flights on June 8 to Bristol with Loganair and Stavanger by SAS, followed by Soutampton via Newcastle on June 15 and Eastern Airways to Teesside and Newcastle on June 22.
AGS Airports chief executive Derek Provan 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.
“These measures, which are in place at all three of our airports, will ensure we help each other to travel safely through our terminals at a time when we are working to get our country and the economy moving again.”
