What SeaPort Airlines does
SeaPort Airlines is a regional commuter airline operating as a division of the Kalinin Group of regional airlines, which also owns Alaska Seaplanes and Island Air Express. The company provides scheduled passenger flights and charter services across the Pacific Northwest, connecting Seattle (Boeing Field), Portland (PDX Business Aviation), Spokane (Felts Field), and Redmond, Oregon (seasonal) using a fleet of more than two dozen nine-seat Pilatus PC-12 turboprop aircraft. The airline's core operating model exploits the sub-12-seat regulatory threshold to operate from small business aviation terminals outside TSA jurisdiction, enabling 20-minute check-in, free adjacent parking, and avoidance of Sea-Tac International Airport congestion. Service frequency is up to 20 daily flights on weekdays with shuttles every 45 minutes on the Portland-Seattle corridor.
The company's revenue model is built on three streams: scheduled passenger tickets (one-time payment at booking), charter services (custom-quoted per mission), and the Corporate Advantage Account program (prepaid balances providing recurring revenue and preferred pricing for frequent business travelers). Go-to-market is direct-to-consumer via the flyseaportair.com website, toll-free phone reservations, and email, supported by Google AdWords remarketing and earned regional media coverage. Customer segments center on time-conscious business travelers and commuters frustrated with major-airport congestion, supplemented by individual leisure travelers and SMB corporate accounts. No AI or machine learning capabilities are evident in operations, marketing, or product features.
SeaPort operates as a private subsidiary under Kalinin Group, led by Chairman and CEO Kent Craford, who co-founded the original SeaPort Airlines in 2008. The current operation was revitalized in 2025 with a new leadership team, tighter business model, and renewed Pacific Northwest focus, followed by 2026 route expansion to Spokane and seasonal Redmond service, including a 19% capacity increase on the Portland-Seattle core route.

SeaPort Airlines competitors and assessment
Company assessmentDirect peers
- Kenmore Air Express: Kenmore Air operates scheduled seaplane and wheeled service between Seattle (Boeing Field), Victoria, and other PNW destinations. Closely comparable to SeaPort in Pacific Northwest geography, Boeing Field hub, and regional business-traveler positioning; also a Kalinin Group sister brand via Alaska Seaplanes.
- Southern Airways Express: Southern Airways is a small scheduled commuter airline operating Part 135 service with Cessna Caravans to underserved US communities. Closely comparable to SeaPort in fleet type (small turboprops), operating model, and regulatory structure.
- Silver Airways: Silver Airways operates scheduled regional turboprop service in Florida and the Caribbean. Comparable to SeaPort as a small scheduled regional carrier using pressurized turboprops on thin-but-recurring city pairs.
- Surf Air Mobility: Surf Air operates scheduled and membership-based regional flights in California and the western US. Comparable to SeaPort in its subscription/recurring-revenue model and focus on underserved regional city pairs using small aircraft.
- Mokulele Airlines: Mokulele Airlines operates scheduled inter-island commuter flights in Hawaii using Cessna Caravans on a Part 135 model. Comparable to SeaPort in small-aircraft scheduled regional service and short-haul shuttle economics.
- JSX: JSX operates scheduled semi-private regional flights using 30-seat Embraer ERJ-135/145 aircraft from private terminals with a hop-on, no-lines experience. Directly comparable to SeaPort's TSA-free, business-aviation-terminal model targeting time-sensitive regional travelers.
- Cape Air: Cape Air operates scheduled regional flights in the Northeast, Midwest, and Caribbean using small Cessna 402s and Tecnam P2012s. Comparable to SeaPort in its Part 135-style regional commuter model and short-haul city-pair focus.
Broad incumbents
- SkyWest Airlines: SkyWest is the largest US regional carrier, operating branded flights for Alaska, Delta, United, and American. Comparable as a regional-scale operator flying short-haul routes across the PNW, but with jet equipment and airline-partner economics versus SeaPort's Part 135 model.
- Alaska Airlines: Alaska Airlines dominates PNW scheduled service from SEA, PDX, and GEG with mainline jets and regional partners. Directly competes with SeaPort on the Seattle-Portland and Seattle-Spokane corridors and is the primary incumbent SeaPort positions itself against.
Regional players
- Harbour Air: Harbour Air operates scheduled seaplane service in British Columbia and the broader Pacific Northwest. Comparable as a small-aircraft scheduled regional operator in SeaPort's geography, though focused on seaplane routes and primarily Canadian.
