Saver-Level Inventory

Saver Award Availability
Definition
Award seats released at the cheapest published price. Typically 0-4 saver seats per flight, often released 11 months out and then closed within hours.
Why it matters
Saver inventory is the only point worth chasing. Use ExpertFlyer or AwardLogic for inventory alerts, and have transfer points pre-positioned in airline programs that don't require multi-day transfers.
