It operated scheduled service from its bases at Portland International Airport (PDX) (Pacific Northwest region) and Memphis International Airport (MEM) (Mid-South region). From 2013 to January 2016 it also operated a Southwest region from San Diego International Airport (SAN).
SeaPort Airlines used the callsign "Sasquatch" to communicate with air traffic controllers. The carrier played off this in early 2013 when it introduced "Roger, The SeaPort Airlines Sasquatch" as the airline's mascot.
On February 5, 2016 it was announced by the airline it had filed for voluntary Chapter 11 bankruptcy after being forced to reduce its route network as a result of a national pilot shortage. Normal day-to-day operations were set to continue during the company reorganization.
As of September 20th 2016, the company is no longer in business after its Chapter 11 bankruptcy was converted to a Chapter 7 liquidation. 
|Cessna 208 Caravan||5||0|
The Cessna 208 Caravan is a single turboprop engine aircraft.
SeaPort Airlines operated scheduled commuter service in two distinct geographical areas connecting rural communities to the national transportation network: the Pacific Northwest with destinations in Oregon, and the Mid-South to include destinations in Arkansas and Texas.
Until January 2016 the airline also had a Southwest region with destinations in California and Mexico.
Pacific Northwest service
SeaPort's Pacific Northwest Service at its Portland International Airport (PDX) hub was historically targeted at commuters between Seattle and Portland wishing to avoid congestion at the larger Seattle-Tacoma International Airport and the main commercial terminal at Portland International Airport. In late 2011, SeaPort began to reinvent its business model and the carrier ended its namesake route between Seattle (Boeing Field) and Portland on January 27, 2012.
As part of this business shift, on January 15, 2012 SeaPort Airlines began nonstop flights between Portland International Airport and North Bend/Coos Bay utilizing Cessna 208 Caravan single turboprop engine aircraft.
On October 21, 2008, SeaPort Airlines was awarded a two-year government grant to provide commercial service from Portland to Eastern Oregon Regional Airport in Pendleton beginning December 1, 2008, replacing subsidized service by Horizon Air.
On March 12, 2010, SeaPort won a two-year Essential Air Service contract to provide three daily flights Sunday through Friday between Salina, Kansas and Kansas City International Airport. As part of this growth SeaPort secured Department of Transportation approval to add daily flights between Kansas City International Airport and Harrison, Arkansas. In July 2011, SeaPort began service to Dallas Love Field from El Dorado and Hot Springs. However, the airline no longer serves Dallas.
In February 2013, SeaPort Airlines announced that its contract to provide Essential Air Service ("EAS") at McKellar-Sipes Regional Airport in Jackson, TN had been extended by the US Department of Transportation through January 31, 2014. The carrier had been awarded a one-year, rather than the typical two-year contract, due to the low number of passengers that used the flights operated by the previous carrier providing EAS, which had put Jackson’s continued eligibility for subsidized air service at risk. However, the airline no longer serves Jackson.
On January 16, 2016, SeaPort ceased service to Salina, Great Bend, and Kansas City, citing a nationwide shortage of regional airline pilots.
On May 1, 2013, the airline began service connecting Imperial/El Centro to San Diego and Burbank. The EAS contract was awarded to SeaPort in January 2013, replacing incumbent carrier SkyWest Airlines, which linked Imperial to Los Angeles.
In July, 2014, SeaPort Airlines announced it would begin nonstop service between Burbank and San Diego on October 1, with four weekday flights each way, and reduced service on weekends.
Later the airline added service to Sacramento and Visalia as well as its first international destination, San Felipe in Mexico.
SeaPort later ceased all operations in California and Mexico on January 15, 2016.
