what is the downside of this statemewnt? For family fares, I can guess that there are more cons than pros to following the practice of being closed as the inventory class is closed. This, because: 1. It won't allow the airline to keep providing dynamic offers to customers while the inventory is completed (choices are reducing and may force a customer to look for other alternatives; go with competition). 2. As a result of reduced options for branded fares, customers may tend to perceive that they are being forced to acquire ancillary products at a higher cost than in the bundled offer, leaving only the option of "a la carte" services. 3. Damage to the brand could result from not always presenting the options to customers. One of the reasons for these "sub-brands" is the intent to boost the airline's strategy. A good point of doing this practice could be to obtain more revenue because of the sale of the remaining branded fares available that are high priced and less appealing for many passengers in the early stages of the flight schedule. However, this could have some drawbacks that need to be pondered
