Alaska Airlines said Thursday it will add five nonstop routes from Seattle-Tacoma International Airport in 2027, beginning with seasonal flights to Guadalajara, Mexico, on March 18. Daily flights to Charlotte, North Carolina, and Norfolk, Virginia, are scheduled to start June 10, followed by Jacksonville, Florida, and Des Moines, Iowa, on June 24. Tickets for the routes are on sale, the airline said.

All four domestic routes are planned for year-round service. The Guadalajara flights are scheduled three times a week through early August. Regional reporting confirmed the five routes. The airline said the additions would bring the number of destinations it serves nonstop from Seattle to 119. For Jacksonville, Norfolk and Des Moines, Alaska describes the routes as the first nonstop links to Seattle. Charlotte already has nonstop service on another airline.

Charlotte and Norfolk start on June 10

Charlotte Douglas International Airport said Alaska will be its ninth domestic airline partner and will fly the route with a Boeing 737. The published schedule has the Seattle flight leaving in the morning and arriving in Charlotte in late afternoon. The return leaves Charlotte shortly before 6 p.m. local time and arrives in Seattle the same evening. Axios reported that the new service adds a carrier to an airport that also saw JetBlue return earlier this year.

Norfolk is scheduled to start the same day. Its Seattle departure is earlier than Charlotte’s, and the return is scheduled for 5:01 p.m. local time. The airline’s schedule and the independent timetable published by AeroRoutes both show daily service. Travelers continuing beyond Seattle will need to check the connection times for the specific flight they select, especially when their next flight leaves before the evening arrival.

Jacksonville and Des Moines follow two weeks later

The June 24 additions also have morning departures from Seattle. The schedule shows a late-afternoon arrival in Jacksonville and a return that gets to Seattle at 9:40 p.m. local time. Des Moines has an earlier return, scheduled to reach Seattle at 5:36 p.m. The routes offer direct options for travelers who previously had to make a connection, while their different arrival times can matter for those continuing through the hub.

The schedule reviewed by AeroRoutes lists Boeing 737-900ER aircraft for Jacksonville and Norfolk, while Horizon Air is scheduled to fly the Des Moines route with an Embraer E175. The airline also describes Des Moines as its first service to Iowa. Taken together, those plans show that the airline is using different aircraft for different markets, with daily service in each case. The booking schedule is the place to check the aircraft and cabin offered on a specific date.

Guadalajara is a seasonal overnight flight

The Guadalajara departure is scheduled for 11:15 p.m. in Seattle, arriving at 5:11 a.m. local time the next day. The northbound flight is scheduled to depart after midday. The overnight timing means the arrival date differs from the departure date for travelers leaving Seattle. The late departure and early arrival also make airport transfers and accommodation times worth checking when booking the trip.

Aviacionline reported that Alaska plans to use a Boeing 737 on the route. The airline’s posted schedule lists service into early August, with Aug. 9 as the published end date, and shows three flights a week. Passengers planning travel around the beginning or end of the season should use the flight calendar for their exact dates. The domestic routes have daily schedules, giving those travelers more choice of departure day.

Alaska’s schedule lists separate start dates for the two directions because the southbound flight crosses midnight. The first departure from Seattle is scheduled for March 18, with the first return from Guadalajara on March 19. That matters to passengers booking separate legs or arranging an airport pickup. The route’s timetable is useful for planning, while the carrier’s booking calendar shows which of the three weekly flights are offered on particular days.

Seattle gains more routes for local and connecting travelers

The additions are part of a broader expansion at Seattle, according to reporting carried by The Spokesman-Review. The airline’s count of 119 nonstop destinations measures the reach of Alaska’s Seattle schedule once the routes are added. The most direct change for local travelers is the ability to fly without changing planes on the new city pairs. For travelers coming from the four U.S. destinations, the schedule also adds a way to reach Alaska’s hub and connect to other flights.

Charlotte’s airport pointed to connections through Seattle to the Pacific Northwest, Alaska and Hawaii. A nonstop flight from Charlotte to Seattle still leaves a separate decision about when and where to connect for those destinations. The departure and arrival times, the seasonal limits on Guadalajara service and the daily frequencies on domestic routes are the practical details that distinguish the five additions. For now, the published schedule sets out the launch dates and planned frequencies for travelers deciding whether the routes fit their 2027 plans.
