Sorry to hear that you're still waiting. The last class we ran was Feb 4 - all 717. A good friend of mine was in that class, and he is still waiting for more new hires so he can maybe get off reserve.
I understood it the same way as you in regards to the postponement of new hire classes due to DC-9 retirement schedule, and transitioning current people over to the 717.... BUT... I know that right now we are short DC-9 FO's. There is a memo in the crew lounge asking DC-9 Captains to please volunteer to fly trips from the right seat because of the shortage. What happened is that we let people (especially FO's) move off the DC-9, and yet we have not retired the -9's in an equal pace with the transitions. This has led to many stories regarding what/where/who is going what/where/who.
It appears on the surface to me and alot of people that there is very poor logistical planning in this company. It has appeared to be like that for some time..... but I also believe that as a company, this can be a strength. I do not believe thay are that incompetent. I believe that they literally think certain operational specific things out daily, believe that management doesn't care what the appearance is, only the fact that they can change logistically on a dime to adapt to the market and economy, regardless of how it looks, and who it inconveniences. This is the difference of a "relatively" small compnay such as us, versus "large" airlines. Since I'm just a line puke I cannot confirm this... only my opinion.
Hope you get a call soon.
