Connecting rural communities to the broader air network.
Founded

Headquarters
Portland, United States
SeaPort Airlines was a small regional carrier based in the United States, primarily serving underserved and rural communities in the Pacific Northwest and Mid-South regions. Operating under the Essential Air Service (EAS) program, the airline provided vital connectivity to communities that would otherwise have limited or no commercial air service.
The airline operated turboprop aircraft on short-haul routes, linking smaller cities and towns to larger hub airports. SeaPort focused on filling gaps in regional air transportation where major carriers did not find it commercially viable to operate.
SeaPort Airlines ceased operations in 2016, leaving several communities it served scrambling to find alternative air service arrangements. Its closure highlighted the ongoing challenges faced by small regional carriers dependent on government subsidies to sustain operations in thin markets.
Hubs & network
SeaPort Airlines primarily operated from Portland International Airport (PDX) and Memphis International Airport (MEM) as its main bases.
Fleet
SeaPort Airlines operated Cessna 208B Grand Caravan and Pilatus PC-12 turboprop aircraft on its regional routes.
