on January 25, 2018, their intention to serve the airport with five daily flights, three to Oakland and two to Las Vegas. However, on November 15, 2018, Southwest reversed that decision and transferred its slots to Alaska Airlines. Between Alaska and United, the initial commercial flight schedule for the airport included 24 daily departures, which was 50 percent higher than airport managers had initially planned for. In June 2018, the FAA announced an additional review of environmental impacts of passenger airline service, delaying the start of service between November 2018 and November 2019. The environmental review was completed in September 2018, and no significant additional environmental impacts were found, clearing the way for commercial service to start in early 2019. Alaska previously announced that it planned to inaugurate service on February 11 with a ceremonial flight to Las Vegas, before ramping up to a full schedule of 18 departures on March 12, 2019. Alaska added that the gradual ramp-up would allow the airline and its employees to ensure operations at the new airport terminal were running smoothly. Alaska later announced in January 2019 that it was tentatively postponing the start of operations from February 11 to March 4, 2019, due to the 2018–19 United States federal government shutdown further delaying governmental approval to begin service. The first Alaska Airlines flight from Paine Field, carrying invited guests to Portland, departed at 10 a.m. on March 4, 2019; it was then followed by public flights to Las Vegas and Phoenix. United began service to Denver and San Francisco on March 31, 2019. The San Francisco flights ceased in March 2020, after the airline found insufficient demand. Within a year of opening, the commercial terminal served more than one million passengers. Long-term plans for the terminal include free luggage carts, a cellphone lot, and a consolidated rental car center. The airport's operators have also stated their desire to see larger planes, including Boeing 737s, serve the terminal and routes to destinations like Hawaii. The commencement of commercial service brought new noise complaints from nearby residents, including 10 households who submitted 62 percent of the 3,656 complaints filed in December 2019. San Juan Airlines announced plans in April 2019 to begin scheduled service from the separate Castle and Cooke Aviation building at Paine Field, in addition to its current charter offerings. Two daily flights to Friday Harbor Airport on San Juan Island began on
