Reading the Eagle threads, it seems they are also having trouble filling classes but slowly getting that under control. I think this mini hiring sprint by Eagle kind of got Eagle's HR needing to play catch up. When things started, they wanted 50 in each class and the norm was around 15-20. It seems now that classes are starting to get up into the 40 range.
Just lurking in all the other airlines thread's, I would agree that most are having problem filling classes, yet are of no shortage of qualified applicants. I wonder where the hold up is?
