Phantom Availability
Phantom Award Availability
Definition
When an award-search tool shows saver availability that actually doesn't exist when you try to book. Caused by stale cache, indirect partner integration delays, or already-booked seats.
Why it matters
Most common with Aeroplan, BA Avios, AAdvantage. Workaround: call to confirm before transferring points, especially for high-value redemptions like Lufthansa First.
