They will definitely hire into it again but currently the 175 program is backlogged while the 145/CR7 programs have been relatively idle since the spring. Based on the current training schedules, I would guess that the 175 will again be offered to new hires in January/February timeframe.

That being said, holding out for the 175 right now would be, in my opinion, a penny wise, pound foolish decision. Highly prized among airline executive management but not very smart for an airline pilot working in a seniority based system. If you hold out for the 175 now, you may be sitting right seat in three years to someone who took the first class offered, hired two months before you but with a much better seniority.
