The Best Incentive Travel Destinations from London

Only the two pillars that genuinely depend on where attendees fly from are re-scored. Value shifts with the fare difference between the US-blend baseline and this origin; air access blends each destination's global nonstop coverage with a published origin-to-region reachability score. Both adjustments flow into the composite at the Index's published pillar weights — value 15%, air access 20%.

• value_o = value + 20 · (fare_US − fare_origin) / max(fare_US, 300), capped ±20
• air_o = 0.5 · air_access + 0.5 · reach(origin → region)
• total_o = total + 0.15 · Δvalue + 0.20 · Δair
• fare = $118 + 0.913 · d^0.75, anchored per destination
• city fares: fare = ($118 + 0.9127 · d^0.75) × destination anchor, d = great-circle km from LHR

Fares come from a distance-based model anchored to each destination — modeled ballparks, not live quotes. Every input is published; no destination pays to be ranked. The global Destination Index is the canonical standing.
