Flights in and out of Alderney could be changed for the second time this month.
The airport is running on reduced hours due to a shortage or air traffic controllers in the island.
The days most impacted will be today and Wednesday.
The operational hours of the Alderney airfield for these two days will be 8am - 1pm and 2.30pm - 6pm.
Aurigny says it will be contacting affected customers.
