Ever wonder why a VFR C150 can fly into ORD on the busiest day and why
at such a busy commerical place they dont try and restrict slow
private aircraft.


A VFR C150 can't fly into ORD on the busiest day and private aircraft of all
speeds are restricted at such busy airports. ORD is in Class B airspace and
on the busiest day a VFR aircraft seeking entry will be told to remain clear
of the Class B airspace. ORD is a high density traffic airport under FAR
Part 93, it is limited to just ten IFR operations per hour by general
aviation aircraft.
