The collapse of airline Flybe will not hit flights between Anglesey to Cardiff according to the company's franchise partner.
Flybe went into administration overnight, putting 2,000 jobs at risk, after a bid for fresh financial support failed.
The airline ran the booking service on the Wales airlink.
But Eastern Airways actually operates the service and this morning stated that flights would continue to operate as normal between the airports in Cardiff and RAF Valley.
The 7.35am service from Cardiff to the island took off as normal this morning.
The booking service has currently been switched to a phone only operation but a new booking system is expected to be up and running in the next few days.
A spokesman said: "Eastern Airways flights will continue to operate as normal and we advise passengers to arrive at their airports as usual today."
They said they will honour any tickets on Flybe services operated by Eastern Airways for travel today, Friday or Sunday.

A spokesman said: "Passengers booked to travel on Flybe flights operated by Eastern Airways, including the Cardiff – Anglesey service, are to check-in as normal with booking confirmation as flights will be departing as normal. We will honour all bookings today and tomorrow and revised details for bookings will be advised via our website in due course. As an independent airline, we shall restore the former stand-alone booking processes and ensure no effect to the regional air services we operate."
Eastern has been asked what will happen to tickets booked with Flybe on the service beyond those dates and if passengers will need to book new tickets.
A statement from Cardiff Airport said: "Flights to Anglesey, Teeside and Aberdeen will continue to operate as normal with Eastern Airways. Customers due to fly with Flybe to other destinations are advised not to travel to the Airport. All flights with other operators are flying as normal."
