I'm an all-rounder commercial jet pilot, as the purpose of GA flying in FS, at least to me, seems a little frivolous, that part can wait until I have more scenery, as GA under the default FS9 scenery is terrible, there is nothing exciting.
So, in the meantime, I invest in commercial jets, both large and small:
PMDG 737 & 747
CLS A330/A340
CaptainSim 707
SSTSIM Concorde
And one payware mega-hub, and one freeware to the same quality, both with AES.
Mega Airport Heathrow 2008
George Grimshaw's Boston Logan
Coming next:
Mega Airport Frankfurt
I've been so spoiled...
Anyway, typical flights for me usually start in Heathrow (though I am not British) and half the time are intercontinental, and the other half leapfrogging, usually ending in JFK in New York.
PMDG has a huge level of automation, so I can usually relax while the fight is in progress.
SSTSIM, however, requires constant attention, but gets you across twice as fast.
Those are my flying habits...
