Weren't LS using a Flightline 142 on the NCLLGW run?
Sunday would have been a difficult day for Flybe, with most weekend travellers having to book single tickets with JET2 for the Friday/Saturday and then the same with Flybe for the Sunday night. The initial pax loads however, have been excellent.
Irrespective of the loadfactor, the cost of operating the Q400 on the route will be approx 40% less than a 146, so although the pax numbers may be the same between Flybe and JET2, Flybe will be making money on this route - probably from the word go!
