First year capt pay is $15/duty hour in the states and $18/duty hour in the Caribbean. The majority of lines have a guaranteed weekly minimum of 35+ hours.
In the states any duty time over 40 hours in a week gets paid time and a half.
In the Caribbean any duty time over 8 hours in a day gets time and a half. For example 9 hours duty time = eight hours at $15 and one at $22.50
$15 x 35 hours = $525 per week = $2100 per month = $25,200 per year before taxes in the states.
