Each vacancy contains basically a saab class and a 900 class or a saab class and a 200 class. Going into the future, it looks like only classes for 900 and saabs will be available. However, if movement from 200 FOs takes place, there will likely be classes for the 200.

As for the day in class that you bid, I'm not sure. It'll happen early on though and if you get a base you don't want, you can set your preference bid up to reflect what you want and then see what happens on the subsequent vacancies. Vacancies have been coming out roughly every 2 weeks and will continue to do so until the hiring stops.

Hope that helps... PM if you need further clarification.
