OPS Watch · 32,392 legs measured · last 90 days · 1 route outbound only
Measured from flights observed on Seoul’s own departure and arrival boards over the last 14 days. Every route below carries its observed weekly frequency, and 14 routes with enough history show how reliably they actually run: on-time share and cancellation rate from the last 90 days. Right now departures are +18 min.
All GMP nonstop destinations, ranked by weekly flights
One row per destination, both directions merged. On time means within 15 minutes of schedule; cancelled is the share of observed legs that never went. Routes with fewer than 20 observed legs show their leg count instead of a shaky number.
