Was browsing trough the flights at biac's website and I found the following thing. Since it wasn't mentioned yet on the 'spottersdatabase' and there was not yet a topic about BRU 09.10 yet , I opened this.
Maybe someone want to spot this one:
ARR---12:10---Porto------AHY 6719---Azerbidjan airlines----A319-100
Plane looks like this , really gorgeous. And typically , another school/working day is there when the specials arrive.

ETD not yet given on biac (might be not be able to check it anymore).
But if the plane is not just another charter wich stands there the whole day I would guess it leaves around 13:20 (NOT CONFIRMED!!!)
