A new airline has agreed to take over twice-daily flights between Cardiff and Anglesey after they were suspended.
LinksAir, which previously ran the Welsh government-subsidised service, said it was out for tender but no contract had been signed with another airline.
But the Welsh government said alternative carrier, Citywing, had now stepped in.
Passengers were told to turn up and travel as normal on Monday.
A Welsh Government spokesman said:
“The provider of the intra Wales service withdrew their service without notice today, but we have secured an alternative carrier to enable the service to continue without interruption.”
