Multi-segment award estimates: inspect every segment
Original explanation or a governed summary with official sources; current official terms remain authoritative.
Rule version and operating carrier
One loyalty programme can price its own flights and partner flights under different rules. Each segment should record origin, destination, operating carrier, cabin, travel date, and rule version. If no exact supported rule matches, show unsupported instead of guessing.
An estimate is not availability
Required miles, taxes, and carrier charges can change. Even when a rule can be calculated, it does not mean a redeemable seat is available. Confirm the final amount and availability in the programme’s official search or booking flow.
