Expanding the Model


I want to fly from San Francisco to New York. What Flight do I take?

My itinerary requires me to take Flight 837 from San Francisco to Chicago and Flight 1024 on to Miami.

And apparently we were wrong when we stated that a Flight arrives at one City.

It seems that a Flight can arrive at multiple cities in sequence, even if my itinerary does not visit all those cities.
