Everyone gets dumped in DAY on the first award, then TYS for a month or two, then finally CLT. Depending on how long training takes you probably won't ever have to sit in DAY and will be TYS based by the time you finish IOE. If you're lucky you'll only have a couple of weeks there before being based in CLT. This is all based on past trends, which may be skewed now that new hire classes have been temporarily halted, and it's very hard to predict how things will go when they restart, and how much they've been able to shorten the gaps in training.
