With prior 121 Jet-time, you'll get a call at 850TT...I was hired at 802 back when they were desperate - right place at the right time.
My numbers for '08 (lineholder)
June: Block 96, Credit 104
May: 96/108
April: 87/102
March: 94/108
February: 84/104
January: 91/102
Considering that that is with flying being very tight, you can squeeze the same. I still had 12+ days off a month...just be creative. My best month was last year, blocking 99.8 hours and crediting 144. Have only credited <100 hours once (reserve month), and brought in 30K first year.
