King County International Airport-Boeing Field (KCIA) is sharing future airport plans at its upcoming open house as part of the Vision 2045 Airport Plan process. The goal is to have a plan that will allow KCIA to evolve and adapt to meet changing aviation needs over the next 20 years. KCIA invites airport tenants, airport users, and community members to learn about the selected preferred alternative which includes projects the airport is including in the Vision 2045 Airport Plan. The preferred alternative was selected based on technical analysis of the airport’s future needs and input shared during the Vision 2045 process. The selected preferred alternative and alternatives considered are available to view on the project website, KCIAPlanning.com. The open house will be held on Thursday, May 14, 2026, from 5:30 to 7:30 p.m. at the KCIA Flight Service Station, 6526 Ellis Ave. S. in Seattle. Attendees can stop by any time to talk with the study team and share their feedback. “The preferred alternative we will share at this at open house is the culmination of our technical work and the feedback from airport tenants, airport users, and the community that helped shape the process,” said airport director John Parrott. More details Attendees can get more details and optionally register for the event at KCIAPlanning.com. There will be no formal presentation. Free parking is available in the building’s parking lot and on nearby streets. A King County Metro bus stop at Ellis Avenue South and South Warsaw Street, across from the KCIA Flight Service Station, serves the 124 and 60 lines. Interpretation will be available in Cantonese, Khmer, Mandarin, Spanish, Tagalog, and Vietnamese. If individuals are unable to attend the open house, the study team has posted information for viewing on the project website, including the preferred alternative and a video presentation explaining the alternative evaluation process. The study team will host an additional open house and engagement opportunities as the process continues through 2026. Learn more about KCIA at kingcounty.gov/airport.
