Part 121 · Reserve, open-time & MEL
Reserve crew
Track reserve crew as LONG_CALL and SHORT_CALL with callout and no-contact handling, so the desk knows who's available and who's been used. Reserve coverage lives in the same system as the lines it backs up. It replaces the reserve list kept on a separate sheet.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Crew desks filling trips from reserve who need to know at a glance who's available and who's already been used, without reconciling a separate list against the schedule.
What it replaces
The reserve list kept on a separate sheet, and callouts recorded as phone notes nobody else can see.
What reserve crew gives you
- Reserve tracked as LONG_CALL and SHORT_CALL
- Callout and no-contact handling
- Reserve coverage in the same system as the lines it backs up
LONG_CALL and SHORT_CALL with callout tracking
Reserve crew tracks as LONG_CALL and SHORT_CALL, with callout and no-contact handling recorded, so the desk knows at a glance who's available and who's already been used. A callout is a recorded action on the reserve record rather than a phone note nobody else can see, and a no-contact tells the desk to move on.
- Reserve tracked as LONG_CALL and SHORT_CALL
- Callout and no-contact handling
- A callout is a recorded action, not a phone note
Coverage in the same system as the lines
Because reserve coverage lives in the same system as the lines it backs up, the desk doesn't reconcile a separate sheet against the schedule when it needs to fill a trip. Reserve and the lines it stands behind sit in one place.
- Reserve coverage in the same system as the lines it backs up
- No separate sheet to reconcile against the schedule
- Reserve and the lines it backs up in one place

How it works
Reserve crew, step by step
Place a reserve crew member as LONG_CALL or SHORT_CALL.
Call out a reserve when a trip needs covering; the callout is recorded.
Mark no-contact when a reserve can't be reached, so the desk knows to move on.
Read reserve coverage in the same system as the lines it backs up.
Questions
Reserve crew — frequently asked
How is reserve crew tracked?
As LONG_CALL and SHORT_CALL, with callout and no-contact handling, so the desk knows who's available and who's been used. Reserve coverage lives in the same system as the lines it backs up.
What happens when a reserve can't be reached?
The desk marks them no-contact, so the status is recorded and the desk knows to move to the next available reserve rather than waiting on a name that won't answer.
