I saw a study that JetBlue did on virtual basing and if you have more than about 40 hotel rooms per night at any particular city, virtual basing could save some serious money. The biggest issue is you need to have a large enough "pool" of local people to make the base work. Basically, everyone who elects to be in the virtual base will get a schedule and also have to cover so many days of SC reserve. In the past, virtual bases were very difficult to manage, but apparently with the advent of PBS and more powerful computers, it should be a simple thing to do that will save the company alot of cash on hotel, transportation, and perdiem costs.
