We exploit exogenous shocks to flight distances over time to estimate the distance effect in airborne trade within panel regressions. We find a negative distance effect, which we interpret as evidence of a link between transportation costs and airborne trade. Notably, this relationship is driven almost entirely by changes at the extensive margin. Specifically, trade in HS 6 product categories with intermittent trading histories becomes dormant when flight distances increase. Conversely, the intensive margin of trade remains largely unaffected.
