The "growth mode" memo alluded to 84-104 new hires for the rest of the year. Heck, this current bid only has 44 vacancies on it. Where is everyone coming up with these 100+ numbers? Are you sure you aren't confusing the total for 2014? I think Alaska will have a total of 160 for the year.
As far as it being "too late for July," what makes you say that? The next class starts on 7/7. They could start another class later in the month.
