Inferring complete demand and actual capacity information from the airline origin and destination survey

Our methods generate itinerary-level demand and actual capacity estimation for each carrier. They are easy and inexpensive to implement. They only utilize the existing data sets (i.e., form 41 and DB1B data). They have better applicability. Compared with the existing method, our methods do not require the route attributes information or the efforts for parameter calibration. The main focus of this paper is to present the new methodology. As a part of future work, our methods may still need to be further validated by using, for example, some internal demand data from carriers.
