Landline is building infrastructure that lets passengers clear security and check in for their flight closer to home before they ever reach the airport. We provide seamless ground connectivity on behalf of American Airlines, Air Canada, and other major carriers integrating booking, secure transport, and baggage handling into a single ticket across a growing North American network. Backed by top-tier venture investors and partners like CLEAR, we've spent years making the travel day seamless for millions of passengers. Now we're building the next piece: secure remote checkpoints that let travelers clear security and check in in the city.
