From Monday (15 June), terminal operating hours will increase to 6am-10pm.
EasyJet, Wizz Air, Ryanair, Belavia, Vueling and Blue Islands will resume flights.
Hand sanitiser stations, protective screens, regular deep cleaning, and social distancing will be introduced and enforced throughout the airport, while face coverings will be mandatory.
Gatwick closed its North Terminal at the end of March.
Chief executive Stewart Wingate said the safety and wellbeing of passengers and airport workers remained Gatwick’s top priority.
"We have introduced a range of new social distancing and hygiene solutions to help this happen so we can all help protect each other when travelling through the airport," he said. "We want people to understand airports and air travel is a safe environment in this Covid-19 travelling world."
Wingate added: "The recent government announcement regarding the 14-day quarantine period for passengers arriving into the UK is, in our opinion, already having an impact on the start of air travel recovery.
"We accept the government’s absolute priority is the protection of public health, but we continue to push for regular, country by country reviews of quarantine regulations, based on medical evidence.”
Gatwick’s new guidance will be published online and will be available via its app, and reinforced by physical signage and a new film.
- Passengers required to wear face coverings within the airport, with Gatwick staff mandated to wear face coverings in passenger-facing areas of the terminals. Face mask vending machines will also be made available at the airport;
- Encouraging good hand hygiene with ample, well signposted hand washing facilities and numerous hand sanitising stations – including touch-free models – throughout;
- Frequent, enhanced deep cleaning of common-use surfaces throughout the airport with dedicated teams visible to respond to any passenger concerns on cleanliness;
- Social distancing procedures in place at check in, security, gate rooms, seating in departure halls and in restaurants, bars and shops;
- Installation of perspex screens throughout the terminals, including check-in desks, and gate rooms.
