Decision logic

— Cash beat award on every cabin tested — Avios redemptions on QR LIS routes are pricing at 1.2¢/point, well below your portfolio's 1.6¢ baseline.
— Skipped Lufthansa Group despite competitive base fare: MUC connection adds 11kg CO₂ and 2h with no comfort gain.
— Tried 4 hidden-city constructions (LIS → MAD throwaway, BOM → LIS → OPO throwaway); none beat Balanced after risk-adjusting for forfeited return.
— Mistake-fare scan returned no anomalies on this route in trailing 14 days.

What I cannot see

— Indian consolidator network (Akbar, Riya, TBO) — these are offline channels; manual call may surface ₹4–8k savings on QR.
— Award space for Star Alliance partners booked through Aeroplan — Seats.aero coverage is incomplete for AC partner award inventory.
— Bundle pricing with hotel — Expedia package math not yet integrated; if you're booking 14 nights in Lisbon, a bundle could reclassify the winner.
