Mesa:
1) 1.5hr call out or 60min if you're at GJT. 2hrs if youre at JFK I believe.
2) Can reduce your monthly guarantee to get extended call-out (12 or 24hr) but thats only if crew planning wants to give any out that month.
3) No min pay for home reserve.
4) 6, 8 and 10 hour ready reserve periods. Pay is 50% of ready (so 3hr credit for 6hr shift.) Must be released after RR ends unless they extend you to the next higher segment (6 to 8, etc.)
5) Morning, evening and standup reserve times (0500-1700, 1200-2400, 1800-0600) but these can be changed by the company if they really want to.
6) Preference system. Call me First, Call Me Last. Trips are assigned in seniority order from the CMF, then no-preference, then in reverse seniority order in the CML -- except if you're on ready in which case it's company's discretion.
7) 10 days off.
8) Theres supposedly a volunteer list for RR, but other than that it is assigned in reverse seniority order.
