Surely,
I would have thought it would cope ok, provided all of these flights aren't checking in at the same time (unlikely as I guess we are talking 1 rotation per day on each route, using a couple of based a/c?)....they seem to manage ok with the 737/A320/757 charters during the Summer.
There also usually seem to be a couple of stands (the ones alongside the new Multi-storey) that are rarely used except during the busiest parts of the day.
I assume BEE will be using the 146 for these routes? - will they make it to Malaga & Murcia with a fullish load one wonders?
Good luck to them anyway - I've already booked to JER in Sept, £53 per head return, including all the "charges".
