1 place to board, none of them "Williamsport" itself. The distance is from the centre — an airport an hour out is a different journey from one thirteen kilometres away, and folding that into a flight time is the false claim this site exists to avoid.
Every destination from Williamsport placed by compass bearing. Not a map — the angle is the only geography kept, so an empty quarter means nothing goes that way, not that it is sea.

All 21 of them, deduped across every terminal — 21 by air.
Our records for journeys from Williamsport were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
