Aurigny is reminding passengers to wear face masks when travelling with the airline.
It says all customers travelling to any destination must wear a mask, and those who are not wearing a mask at the departure gate will be denied boarding and will not be able to travel.
It will be each customer’s responsibility to ensure they have a mask and they should continue to wear their masks until they leave the airport at their destination.
A limited supply of masks are for sale at Guernsey Airport, but stock levels cannot be guaranteed.
Passengers who remove their masks during the flight or fail to comply with the requirement will be treated as a 'disruptive passenger'.
The only people who are exempt from the rule are children up to the age of six and people with a medical reason.
Aurigny says the introduction of this requirement means more people will be able to travel per aircraft and customers will not have to practice social distancing on board.
