The conference call said two 717 in the first half of 2004 and four more in the second half. The 737's should start arriving in June, with 8 of them here by year's end. Figue 10 weeks training from Indoc through IOE . . . so that says pool fills the March classes, then April newhires for the 737, probably interviewing in Feb or March.
Figure 12 pilots per plane, and 15 retirements for the year, and you end up with about 180 pilots.
