Looking at what the guys make at Focus compared to you... They are a little better off if they don't stay out past 19 days.
Focus only pasy 3.5 hours past 19 days (but its over a two month period so they could keep you out 21 days one month and 17 the next = no overtime)

No guarantee on home basing.

Not paid block to block only on flight plan.

No pay for DH.

$2 per hour perdiem - never a penny more.

I think your slary should be higher, but overall, not a bad contract for an ACMI carrier.
