I did nothing but standups at OO for almost ten years. It allowed me to have a completely different career at the same time outside of aviation. I'd usually do Thurs, Fri, and Sat stand-ups. I'd work Mon-Fri in the office , drive to the airport on Thursdays, do a stand-up, drive back to the office, then back to the airport Friday night, then home on Saturdays. There's absolutely no way I could have done my other job if stand-ups hadn't existed.
Some of them were easy. The soft time was amazing. I'd fly ~300 block and credit 1000/yr. Some of the trips gave you almost legal rest. Like SFO-STS, you'd be wheels up at 1930 and in the hotel by 2015. Then back out again at 0530 for an 0615 departure, and back in my car by 0715. Some of them were terrible, like SFO-MRY which only gave us 4 hours of sleep opportunity.
The crews were great. You'd get to know everyone because you flew with the same people all the time. We called ourselves vampires and it was rare that we flew in daylight hours.
Standups weren't for everyone, but I loved them. Well, most of them. One time I accidentally bid Edmonton standups from SFO. Those were a complete nightmare. But overall? I'd do them again in a heartbeat.
