St. Mary's Airport is the main air gateway to the Isles of Scilly, an archipelago located approximately 45 kilometres southwest of Land's End, Cornwall. It serves the island of St. Mary's, the largest of the Scilly islands, and handles scheduled, charter, and helicopter services connecting the islands to the UK mainland. The airport is one of the smallest commercial airports in the United Kingdom, with a short grass and tarmac runway infrastructure suited to light aircraft and small turboprops. It is operated by the Council of the Isles of Scilly and plays a vital role in sustaining the island community, providing a lifeline link for residents and a key access route for tourists. Given the islands' remote location and limited ferry connections, the airport sees significant seasonal traffic, particularly in summer months when tourism peaks. Skybus, operated by Isles of Scilly Travel, is the primary airline serving the airport with routes to Land's End, Newquay, and Exeter.
