Aurigny flights continue to be disrupted following a bird strike on Friday (17 March).
The airline says significant damage was done to its Embraer 195 jet's engine cowling following 'a substantial bird strike'.
Aurigny says the part affected isn't held as regular spares.
It has led to disruption and delays to the airline's schedule while it sources a replacement.
A loan aircraft has been brought in, and passengers travelling over the weekend were moved onto alternative services.
The leased plane is understood to be a 17.5 year old G-POWM Airbus A320-232 from Titan Airways.
Guernsey airport stayed open late to allow for the rescheduled flights.
Saturday's 14:50 flight from Guernsey to Gatwick was finally in the air at 9pm. The return 17:50 flight from Gatwick arrived in Guernsey at 11.20pm.
Two have been cancelled today (Monday 20 March), but Aurigny says all other services are expected to operate as normal.
The airline apologised to its passengers and said it was doing 'its utmost' to ensure minimal disruption to their travel plans.
