1. What does itinerary, segment, flight, equiment and seat exactly mean in the Business Domain Model?
In my opinion, a segment is defined as one takeoff and one landing on an itinerary. For example, if you want to travel from country A to country C and there's stopoever at B (A->B->C), there'll be two segments included in the itinerary. But why a segment only has one flight in the model, I had thought there should be more than one flight for a segment?
The equiment is an airplane, I think.
But what confused me is that the segment and flight have the one to one relationship in the Business Domain Model?
