This would be a return to STN for Transavia as they previously served RTM about 18 years ago.
I agree with the previous comments regarding Transavia and a link from STN to Paris. I also agree with the previous comments regarding SAS possibly resuming CPH rather than fellow Sky Team members Air France or KLM resuming STN from their respective hubs.
But nonetheless it's great to see another airline at STN and hopefully we're see some more announcements regarding new airlines in the coming months.
