Reserve at Horizon is as follows:
- 13 days off in 35 day bid period.
- 2 hour call-out in SEA/PDX, 1:30 in the other bases.
- 14-hour blocks of being contactable. There's AM and PM, with different start/end times depending on the base.
- Airport reserve also exists, but tends to go senior. Basically, sit in the airport and wait.
