Chris,

-On average you get 7 g-days/month.
-Every year you get whole month on reserve with alternating service periods
(i.e.from 6am-2pm on AM days, and on PM days your on from 2pm 'til 10pm.)
Also during your month n reserve you get paid an average of what
you've made in the past months + per diem for any flights.
-As an expat, your seniority goes down the drain, but you can make a "formal" request for the flights you want every month and they are usually pretty good about assigning them but no guarantees. On the contrary if you where panamanian, you could just call in the request to the schedulers...

Best of luck to you all!!
