Landline coaches debut on West Coast with Sonoma County to SFO service

Ground transportation to major airports keeps expanding beyond the usual car rental or rideshare options. On November 17, passengers flying from San Francisco will gain a new way to reach the airport: a direct coach service from Charles M. Schulz-Sonoma County Airport (STS) in wine country, operated by Landline.

The coach service launches with eight daily round trips, covering the roughly two-hour journey between STS and SFO’s International Terminal. Landline is operating the route independently rather than as a white-labeled airline service, continuing a trend the company has pursued alongside its airline-branded operations.

Service Structure and Pricing

Fares and Booking

Adult passengers pay $55 per one-way ticket, while children under 15 travel free. The fares sit below what travelers might expect for a car rental, though Landline notes the rides do not earn or qualify for airline loyalty points. Booking happens through Landline’s website, bypassing travel agents or airline reservation systems.

This pricing model reflects Landline’s original mission, which the company launched seven years ago to offer lower-cost surface transportation as an alternative to regional flights on short-haul routes.

Buses and Amenities

All Landline coaches are configured with 2-1 seating and equipped with high-speed Starlink connectivity. The configuration differs from typical intercity bus seating, offering more legroom per passenger and enabling travelers to work or stream content during their trip.

Passengers check in and drop their bags at the STS terminal before boarding. Once inside security at STS, travelers proceed to the coach bay and board their assigned bus.

At SFO, coaches arrive directly at Gate A3 in the International Terminal, allowing passengers to proceed to connecting flights without recleaning security. This setup functions similarly to transferring between airline terminals at a major hub, though with a ground leg substituting for an air segment.

Luggage transfers automatically from STS to the connecting flight at SFO, eliminating the need for travelers to retrieve and re-check bags. For return trips, passengers collect luggage at SFO’s baggage claim and board Landline coaches at the curb.

Partner Airlines and Terminal Placement

Launch Partners

Five airlines are launching with the service: Alaska Airlines, American Airlines, Hawaiian Airlines, JetBlue Airways, and United Airlines. Landline stated additional partners are planned for the future, though no timeline or names were announced.

Gate and Terminal Considerations

The choice of airlines matters for gate placement. Gate A3 serves terminals 1 and the international terminal, making it convenient for Alaska, American, Hawaiian, and JetBlue operations. United, however, operates from Terminal 3. Landline founder and CEO David Sunde acknowledged this friction in remarks to aviation reporters, indicating the company is working with SFO to secure a more centrally located gate as the service expands.

“We’re successful in markets when we convince people not to drive themselves,” Sunde said. “We think that the combination of an airside arrival, bag transfer to multiple major carriers and a comfortable seat with high-speed Wi-Fi is hard to beat.”

Landline’s Expansion Trajectory

Recent Growth

The SFO-STS launch represents the latest addition to Landline’s expanding network. The company has roughly doubled in size during 2026 alone, according to Sunde. That growth follows earlier milestones, including the 2023 debut of airside-to-airside bus service at Philadelphia International Airport with American Airlines—buses that operate entirely inside security between two airports.

Established Routes and Demand

Landline’s most established route operates between Northern Colorado Regional Airport (FNL) in Fort Collins and Denver International Airport (DEN). That service began in 2021 with four daily round trips and now runs 19 round trips per day, demonstrating substantial passenger demand for this travel mode.

The company also operates a remote terminal model in Framingham, Massachusetts, near Boston. What began as a three-month trial with Massport, Boston’s airport operator, was extended through March 2027 less than 30 days after launch. In late June, when the extension was announced, Landline staff reported buses frequently departed at full capacity with parking at the facility at maximum occupancy.

Future Expansion in Northern California

If the SFO-STS route succeeds, Sunde indicated Monterey Regional Airport (MRY) on California’s coast, Stockton Metropolitan Airport (SCK) in the Central Valley, Modesto City-County Airport (MOD), and Sacramento International Airport (SMF) could follow. Sunde suggested these are natural next steps rather than firm plans.

All four airports either currently or formerly supported commercial air service to SFO. United operates up to four flights daily from SFO to both Monterey and Sacramento according to current schedules. The SFO-STS air route suspended operations in 2022, while the SFO-MOD route ended in 2014 and SFO-SCK in 1993.

Substituting coaches for these short-haul flights could help address SFO’s chronic flight congestion, particularly during adverse weather. For travelers, the trade-off between a 45-minute flight and a 90-minute to two-hour coach ride with automatic luggage handling may favor ground transportation under normal conditions, especially when factoring in drive time to and from the starting airport.

Implications for Bay Area Travelers

The launch brings a new ground transportation option to a region where driving to SFO from wine country typically requires two to three hours depending on traffic, parking fees, and whether travelers must return a rental car. Landline’s model places luggage handling and security clearance at the origin airport rather than the destination, reducing overall travel friction.

Passengers cannot earn airline loyalty points on these fares, which matters less for infrequent travelers but limits appeal to frequent flyers seeking status miles. However, members of loyalty programs retain status benefits on connecting flights booked through their preferred airline.

The service begins November 17, marking Landline’s first West Coast presence and a potential test case for whether regional ground transportation can shift passenger behavior away from both short-haul flights and personal vehicle drives to major airports.
