What is the selection process for reserve callouts? At my regional, we have a hierarchy that starts with calling out people who are already out first, then a number of things, and then you can preference first/last out in PBS. Can you do it in a similar way at Spirit?

Generally, Long Call gets called first. Inside of long call callout (14 hrs) the Short call priority is based first on how many days of availability you have vs how many days the trip is. If a 3 day needs coverage then it will first go to someone with 3 days remaining. Seniority among multiple with the same days available. After that it's PFM.

If you want to be called first, you can designate yourself as such on Flica. That list goes in seniority order.

It's fewest days available first, followed by seniority next, obviously depending on the length of the trip. We don't use the first in/last out deal here.

So does your seniority get you called last or first?

Both...haha...

"within each group, rank those pilots electing to be called first, senior to junior, followed by the remain- ing pilots, junior to senior."

So if you want to fly, its senior to junior, not wanting to fly its the inverse. But as stated, If I have 3 days available and a junior pilot has 4 days available and a 3 day trip comes up, my phone will ring. If I have 3 days available and a junior pilot has 3 days available and a 3 day comes up, they will get the call, even if they just came off a trip a day prior. The one caveat, sometimes rare, is if the junior pilot will credit about 72 hours, then the schedule can bypass them for another pilot.

SlimBob basically said the same thing I did.
I dont know what pilotnicco means by "fewest days available first"

You were endeavor right? The difference with call me first here is you can change it per day of reserve a couple of days out. Unlike 9E where if I remember you were it for the whole month.

Awesome, thanks for taking the time to explain it.

You summed it up perfectly, but I was basically just referring to what you said. If you have 1 day left, they're more likely to call that person vs someone with 4 days left. Assuming it's a day trip or something.

It behooves them to keep max options open. E.g. I thought I was gonna get a trip assigned, but they gave it to an LCR, and kept me, on SCR, available.
