Revenue management

On a flight to Goa, two passengers were discussing about the price they paid for the flight and hotel. They were amazed at the price difference as one of them was charged 6800 INR for a round trip airfare and 30000 INR for a hotel and the other 4600 INR for the airfare and just 18000 INR for the same hotel. The first passenger had booked his flight and hotel only one day in advance while the other a month in advance. How can the same airline or hotel manage profit by charging so discriminately? The answer to this amusing question is “Revenue Management” .
