SeaPort Airlines 9-Passenger Pilatus PC-12 Will Offer Boeing Field Air Shuttle A commercial airplane will depart from Spokane’s historic Felts Field general aviation airport for Boeing Field next week for the first time since 1946, allowing passengers to avoid Transportation Security Administration (TSA) checkpoints.The Pilatus is one of four in SeaPort Airline’s new Pacific Northwest fleet, which will begin offering four round trips to Seattle’s Boeing Field most days, starting March 9. “It revolutionizes the way that people get between our two great cities,” chief pilot Ian Fisk said. “And it gives people a little bit of their precious time back.” “You can wake up in Spokane, do a full day’s business in Seattle and be back home here for dinner,” said Kent Craford, CEO of SeaPort’s parent company, Kalinin Companies.
