Certainly an unexpected route
Indeed, I think another German, Med, or UK domestic destination (eg, SEN) was thought more likely.
This one has a very short season of only around 2 months, so looks speculative (or aligned to a Danish tour operator who may have bought a lot of the seats?).
Wondering if all of this years Ryanair and Eurowings destinations are returning next year? (I know ALC is operating through the winter, so assume that is)
Looks like Flybe's are, with the exception of STN.
