Route brief · BOS → LCA
We track this route, but every cached fare we held for it has expired — the last one on August 30, 2026. That does not mean the route is expensive today; it means our crawl has not turned up a fare on it since, so we have nothing of our own to show you and will not invent one. The route stays on the board and this page fills back in the moment a fare returns.
Around 13 hours in the air, BOS → LCA.
