I agree. However, there have been instances where a plane was diverted to an airport almost at the destination, for whatever reason but usually due to weather, and the airline cancels the remaining flight. It is up to you to find your way. Hell, I landed at one airport 10 miles away from my destination due to weather and we had to call for a cab to get to the airport where we were expected.
I could easily see New England airports, where airports are so close to each other, stranding passengers 'close enough' to their destination.
