Well that's interesting. Seems month to month block hours are increasing by large %'s proportional to our green slips we've been handing out the last 6 months. If UNA'S returning were just filling the gap and now increase in hours, I'd say hiring makes no sense. With more flights coming each month and some months having 3x more green slips than ever recorded for that month, hiring large numbers seems to make sense to me. But I may be overlooking something....
