I'm curious how this was funded. If the authors had asked most anyone involved in Airline reservation management they would have told them this plain and simple as it is no secret. Yield management and airline network dynamics are just some of the drivers for these "common sense violations".

Also just to correct another comment on how often fares change. For international flights airlines can publish new fares to ATPCO up to 10 times per day however with newer pricing strategies/technologies such as bid-price the fares can change to meet the demand curve in near realtime.

Airline pricing and revenue management is a very complex and interesting topic that has always pushed the envelope of technology and business management. There is a reason why google purchased ITA. I was really excited to see a paper on the topic post on HN but in the end this study has very little substance to add to the many bodies of work out there.
