So I have read several people saying delta is trying to clear about the pool and have even said their goal is to have the pool empty by April (more instructors? More sim slots?). Is this realistic or even possible considering Twister just posted he is still waiting at 4 months?

When I hear empty pool that makes me think that once you have the CJO you would have a couple of weeks and start training. I have an interview in April and if all goes well I'm trying to get an idea of if there will still be a 4+ month swim by then.
