You'd be good timewise for reserve to either airport from anywhere in the city. LGA is easier from the Bronx, Manhattan, and northern Queens (Astoria, Elmhurst, Corona, and Flushing). JFK is easier from pretty much anywhere else in Queens, as well as from Brooklyn. Kew Gardens is centrally located between the two airports and a decent neighborhood to boot.
