Big delay for SN 3604 from MRS on 23 Jun

[sn26567]

SN 3604/AA 7162 from MRS due to arrive at BRU at 8:25 on 23 Jun has been delayed until 14:45.

Any idea why?

... and another problem for SN 2054/BA 4974 from BRS, due to arrive at 13:05 and cancelled outright.

Why

Note: in both cases the plane is a BAe 146-200. The same aircraft having technical problems? Or just an insufficient number of pax?

Furthermore, flight SN 3591/AY 6611 to LYS, dep. 17:30 is also cancelled (but this should have been an ARJ 85). Maybe because Luchzak did not show up for work?
