No break in hiring or training, as far as I know. Just lots of applicants and interest in Frontier right now (something about being at the beginning of a big hiring wave appeals to folks, I guess). Frontier doesn't hire into a pool, so classes are filled 4-6 weeks earlier. Interviews are usually conducted over 3 days, once a month, to fill a class of 24 for the following month or the next month. i.e. May interviewees filled the last slots in June and the rest went to July's class. No breaks, just busy. Which is great news for those getting interviews now! For those still waiting, just be patient. Your phone call will come.
