Not that it really matters.... even pre-cleared flights must still operate to airfields with C&I processing capability, which LGA is.
Well, actually it does matter. LGA
has that technical capability, but on a limited scale--meaning that airlines cannot simply fly there from anywhere they want. Yes, there are Customs/INS agents on staff at the airport, for private aircraft or emergencies, but the airport is not set up to handle planeloads of international arrivals on a regular basis--the passenger terminals are domestic only. When you arrive at LGA
from a foreign airport with preclearance facilities, it is no different from arriving on a domestic flight--you just step off the plane and are free to go wherever you want. So, the reality is that airlines can operate international nonstops to LGA
only from those locations with preclearance facilities (including, as I learned today, AUA).
