I had the opportunity to participate in a sightseeing flight on board of a VLM Fokker-50 (base at EBAW, Belgium).
The aircraft is nice to fly with, there was more legroom than I expected. The only thing that drew my attention is that, when applying throttle on take-off, the aircraft started to shake very heavily. On this website, I was told that this was possibly due to the fact that VLM pilots hold the parking brakes until the engines spool up. But don't worry, not many airlines do this (I think) and it was great!
Enjoy your flight! And if you'd like to see some pictures taken from the inside of a Fokker-50, check out http://users.telenet.be/PowerCorruptionLies/Roundflights.htm
