According to what I have heard recently, they are in financial trouble at the moment and lots of pilots have been fired (Embraer and ATR fleet). They often sack pilots even those with a significant experience and quite high seniority while in the meantime they replace those guys by wannabe pilots willing to pay for a type rating and 500 hours free (almost) of salary.
Their ATR75s PAX version are almost never flying and this is indeed a pain for the company.
The MD82 fleet I don't really know about it, but since Spanair crashed one in Madrid last year, the Real Madrid team don't want to travel in that flying rubish anymore.
The B737 fleet seems to be going well though. Those aircraft are always flying. Lots of contracts with DHL (when the B757 is too big for some routes).
