As I am only familiar with the NYC parking, I looked it up and here is what I found:
Parking is provided for flight attendants working rotations out of the co-domiciles in Ontario (ONT) at the XXXX hotel and in Orange County (SNA) at the XXXX Hotel These hotels are the only authorized parking areas for flight attendants working a rotation originating from ONT or SNA. Parking at other locations for rotations at these terminals is not eligible for reimbursement. ----crossed out name of hotel for security reasons.
For commuters: Commuters must submit a Commuter Request authorization form each year, and may only receive paid parking for one base. The base authorization form is available in each base and must be signed by a local base Field Service Manager.
Cash out option:
Active LAX-based flight attendants may choose to participate in the California Parking Cash-Out program in lieu of paid parking at LAX or another base. A taxable cash allowance of $45.00 per month is available by completing an application every 6 months and meeting the program requirements. Flight attendants participating in a leave of any kind will not receive a parking allowance for inactive months.
SFO is just SFO not SJU/OAK
