I'm sure they have multiple gates that could handle an e175, but at a busy time of day, they may all be occupied back-to-back. At any rate, @

Regarding landing at the wrong airport, it's definitely an inconvenience, but to me it seems like a much more reasonable option than delaying the flight further and wasting fuel hopping from JFK to LGA.
