Having spoken to someone at JXT today the first flight has about 6 booked on it. I'd imagine it's going to be slow going but it will pick up. 6 PAX at an average price of £93.60 equal £562 which on a 30 minute sector should mean a bit of a profit on the J31. Not a massive one, but a profit all the same.
How come I am still able to book 16 seats on it if I wish? 18-16=2, not 6.
Anyway, if there are 6 pax onboard, I am sure they will return if the service is good enough!
BUT if the airline can fill planes like M2, then they maybe able to pull off this mission of domestic niche services from BLK!
Good luck to the airline!
