VFR flights in the class B isn't the thing making it rare.
But having one of the commercial operators go VFR is basically unheard of.
Also landing VFR is very very rare at LGA. The environment is just too busy to have someone who can't fly IFR.
JFK occasionally allows VFR into the field with prior coordination. But i've also heard that go sideways more than once.
Landing VFR 22R when the heavies are on a chain into 22L isn't fun.
Controllers also get it wrong or rather confuse the VFR pilots because they speak a different language.
"Cleared for the visual approach 22 R, fly heading 250 to join the final approach course!"
You guessed it, stayed on the 250 heading.
Heard another flight going VFR into 22R veer to the left.
But that was a business jet doing a reposition i believe.
He got to fly a bonus round.
The really unusual thing is the airline flight, even if it's a repo, go VFR.
Most aren't allowed to do that due to internal regulations.
