Seaborne Virgin Island Inc, operating as Seaborne Airlines, is a FAR Part 121 airline headquartered in Carolina, Puerto Rico, near the territory's capital of San Juan. It operates a seaplane shuttle service between St. Croix and St. Thomas. Originally headquartered on St. Croix in the US Virgin Islands, the company relocated to Puerto Rico in 2014.
Since April 2018, the airline had been owned by its parent company Silver Airways. On June 11, 2025, Silver Airways ceased all operations and sold all their assets.
