airline revenue management. The idea was simple if its implementation was less so: airlines shouldn’ t optimize each flight or seat independently. Consider a flight from Minneapolis to Tokyo. One passenger occupies a seat on the flight, but the economics of that seat depend on the entire flight network. Another passenger might want the same seat but is traveling from Minneapolis to Detroit. Yet another traveler might be connecting onward to |
Tokyo. The question becomes: What’ s the economic value of keeping the seat available for a potentially higher-value itinerary rather than selling it now? Applying IDeaS’ Opportunity Cost postulate and it becomes clear: A seat isn’ t worth what the next passenger will pay for it; it’ s worth what you might lose by giving it to that passenger instead of someone else. Leg-based optimization was conceived.
To this day, Delta uses some

version of a solution IDeaS designed years ago.
CHANNELING HOTELS Many of IDeaS’ airline applications are relevant to the hotel industry because, as Nagalia observes, both products are similar.“ You have fixed capacity, different types of paying customers and inconsistent demand,” he said.“ When you have a combination of these things, there’ s opportunity to give

different people different prices and for different products based on their willingness to buy.” As Nagalia recalls, the biggest challenge facing IDeaS at the outset was resistance.“ It was making them realize that they were leaving money on the table,” he said.
Northwest Airlines was a bridge to hotels and built on a similar concept: perishable inventory. A hotel has a fixed number of rooms and once a room isn’ t sold, it disappears
