Shambles and certainly not what Southend needs...
I would forget OLT..It was possible to book, so god knows what the fuss was about and why flights are cancelled.
SEN: are better of without them.
We had at BLK Danish Air Transport (DAT connecting BLK with Northern France, although billed Paris.
Botton like their website BLK to Albert Picardie Airport never really happened...We could go on the website, maybe find a one way booking.At least the website was in English.
I think maybe SEN might have put their pax in the picture, especially if tickets had been booked.
