Incheon International Airport (ICN) tracks 8 destinations, all international and all in South Asia, split 5 medium-haul and 3 long-haul. Four of the eight — Kathmandu, Delhi, Mumbai and Colombo — carry a verified historical direct-service record.
Korean Air is the common thread on three of Seoul's four verified routes, Kathmandu, Mumbai and Colombo, with Air India and Asiana Airlines joining on the fourth, Delhi. The unverified half of the list — Dhaka, Lahore, Islamabad and Karachi — sits at comparable or even shorter distances than several verified routes, so the gap looks more like a data-coverage question than a genuine service gap. Agents should check live GDS availability on those four before assuming no routing exists.
All 8 of Seoul's tracked connections are international: 5 medium-haul, 4.4 to 5.7 hours, and 3 long-haul, 6.5 to 6.8 hours, all to South Asian cities. Half carry verified historical service.

Four of Seoul's eight tracked connections — Kathmandu, Delhi, Mumbai and Colombo — show a verified historical operating record, three of them on Korean Air.
OpenFlights' historical route dataset records 2 carriers operating this city pair, flying Airbus A330-300. It's the best-served pair in Seoul's whole tracked network — still confirm current-day operation and schedule in your GDS before quoting, since this dataset reflects historical service, not a live timetable.

Replace xxx with the destination's own 3-letter IATA code from the tables above — the availability-check syntax itself doesn't change by destination, only the city pair does.
8, and none are domestic — all 8 tracked connections from Seoul are international, all within South Asia.
Korean Air, with a verified historical record on 3 of Seoul's 4 confirmed routes: Kathmandu, Mumbai and Colombo. Delhi, the fourth verified route, shows Air India and Asiana Airlines instead.
No — neither carries a verified historical direct-service record in this dataset, though both sit at distances comparable to verified routes like Delhi and Kathmandu.
Karachi, at 5,715 km and about 6.7 hours — one of the three long-haul entries, and one without a verified operating record here.
It's mixed rather than a clean trend: the shortest route, Dhaka at 3,736 km, has no verified record, while two of the three longest routes, Mumbai and Colombo, do. Distance alone doesn't predict verification in this dataset.
