I sat short call at one point, waiting to be used, with 2 other people (overlapping, no less). They had 2 trips in NYC and I couldn't even call crew scheduling (got hung up on 3 times while listening to the sweet hold music) to try and grab them. I would need to be released from SC early to take them (ended at 2200, report was 0600) and it was an easy fix. The end result: I didn't get either trip, ended SC with a credit, went home, and they gave -both- trips to Green Slips less than 12 hours out.
