The Fleet Strategy & Portfolio Management function maintains the authoritative ledger of every aircraft in the enterprise fleet and ensures that every operational decision is grounded in accurate, real-time data.

This role requires deep aviation maintenance expertise, demonstrated authority with maintenance organization
