Expect 2 years of reserve, give or take a few months. 145 people can chime in on flying/not flying on reserve. Reserve is 11 days off a month, 5 days on, 3 off with a 2 off in there somewhere. 4 commuter hotels. Preassigned 4 am reserve availability period on day one, you can request something else 10am-2pm central the day prior and find out whether you got it 4-4.20pm. Call in to confirm it 5pm-9pm central.
Need 2 flights at least an hour apart for your commuter policy.
