One thing you can try to do as a reserve pilot to increase your pay is to pick up Open Time which pays 120% of base pay.

But as a reserve pilot you can only pick up open time on your 11 days off.

The OT you pick up increases your guarantee by the value of the trip.

When you are on your reserve days, you try not to fly so that your days "on" are your days "off".

So say you are able to pick up 8 hours of OT flying on your days off.

Your 75 hour guarantee as a reserve pilot is now 75 hours + 9.6 hours or 84.6 hours of pay for the month.
