1am vs 3am short call's aren't much different in my book. You won't get that 1am but 3am is pretty common overall to get pilots in position for that 5am report.

People are also conflating the old contract SC usage with the new contract. My experience is I'm already used on the vast majority of SC assignments I have received. Going forward I expect more SC per month and more usage while on SC because of the 18 hour call out. Plus day 1 is still a possible 10am show at the earliest with the only change being an extra 3 hours notice of that 10am-6pm report on day 1.

I've generally said for many categories here you are on SC unless you are on LC even if the book answer is the other way around. Adding 1 hour of pay for an unused SC is pretty cheap if it will save potential GS or the airport standby assignments. They extra hour of pay is great, but if it forces a reserve to need a hotel then it's a wash.
