I was hired at the end of September, got off IOE in January, and held CLT in February. So I was based in Cinci for 2 weeks(ish). If they can keep hiring 10 a class, like they had show up yesterday, that'll be more people below you than I had out of training.
I'm expecting 8 months- a year of reserve.
And it's a blended schedule so you have no say in which plane you fly unless you have a good bit of seniority.
