Clean airport, great variety of destinations (also international). The security personnel ist very unfriendly and rude. Even to old people, who might fly for the first time and do clearly not know the drill. Not a single hand to help only harsh comments. The waiting time at the check in (or even only baggage drop off) is way too long. They should check out Amsterdam or even Eindhoven where you can drop off your baggage by yourself! That would be a great improvement.
