If your on reserve you may just break guarantee if it gets busy. But either way..reserve doesn't have to be a paycut...just pick up stuff on an off day (if your not commuting). I was probably home twice as much on reserve vs having a line..and many months by picking stuff up I made > or = the pay i'd make on line. Went 5 months at one point without having a 4 day trip and being one of the most junior pilots in domicile. So its not all bad
