Even if Sea Air were a more established airline, I just can't understand why they think they will be able to sell tickets for a route between Luton and a summer-holiday-centric destination like Rijeka in Croatia starting in late October. Furthermore, it seems to fly 1x weekly from Luton to Rijeka, but 2x weekly form Rijeka to Luton.
Seems so bizarre, that my gut tells me there's something more to this but I just don't have the full story.
