2nd Pakistan B772LR on delivery

Should be departing BFI at 1730z today as PIA7774 for JFK.

PIA7774 arrived last Thursday, March 23, at JFK and went no further.

Was it supposed to go onward to Pakistan in ‘delivery’ mode, or did it go into commercial service at JFK and proceed under a normal flight number on a PIA flight route?

I know the first 772LR did this, I believe in MAN, picking up passengers on the way to Pakistan for the first time, so I wouldn’t be surprised if that is what happened here.

Departed JFK as PIA7744 if you look.
