No international airports hereabouts notwithstanding the many high vapour trails of planes flying to and fro across the Atlantic. But, if you must, you can fly from Glasgow to Campbeltown, Islay and Tiree with Loganair which seems to be on a bit of a roll and expanding its routes. There is also a small operation — Hebridean Air Services — which runs scheduled flights from Oban aerodrome in North Connel, hardly an airport although it badges itself as such to Coll, Colonsay and Tiree (but by no means every day of the week). You may be able to sneak on a sight-seeing trip if the plane it isn't full.
