Having been flying European Shorthaul from quite a few years now, I don't think I have ever flown a complete flight to Flight Plan. Always get directs, even if it only takes a dog leg out. In about 70% of cases if we want a direct we are normally given it or something similar when we ask or within a couple of minutes of asking. Generally, ATC route us direct before we can ask for it.
It might be simpler to ask has anyone ever flown an entire route as filed...I reckon there would be fewer takers on that. Obviously really shortflights don't count as it's hard to deviate from a straight line over a few miles.
Anyone else?
