Hey Doug,
JB has almost 40 planes now...granted the majority of our services are JFK-FL & CA but we also have DEN,LAS,MSY,SEA,SLC,BTV,and a couple places in upstate New York. Oh and who can forget SJU

!.
I went over to Flight Info and got some average (keyword:
AVERAGE ) monthly/yearly hours for the majors
Disclamer: I don't know how accurate these are...it's just to give us something to work with! These times are flight time only!
UAL=36/432
AAL=39/468
NWA=40/480
DAL=45/540
ALSKA=46/552
JB=47/564
CAL=49/588
USA=50/600
FRNT=50/600
ATRAN=51/612
SWA=62/744
Now granted these are the average. I think in an earlier post Doug said he flew close to 700 hours so he would be in the top end for Delta. We all know AirTran and SWA will never fly passnegers between DSM and Bejing.....but is there a need to? A lot of that of flying being done(esp. Intl) is operating under that "because we can" pretext! Kinda like showing the company's colors. Pan Am did that and look what happened to them!
