Alaska Airlines Grows More With 4 New US Cities From Seattle & 1 Seasonal Route To Mexico In 2027

Alaska Airlines announced an aggressive expansion plan for 2027 focused on Seattle-Tacoma International Airport, pledging five additional nonstop routes from Seattle, including year-round services to Charlotte, Norfolk, Jacksonville, and Des Moines, as well as a seasonal connection to Guadalajara, Mexico. The news signals a broader network-growth push for Alaska Airlines from Seattle, even as the carrier confronted profitability challenges in its most recent quarter. The information originates from Simple Flying’s coverage of Alaska’s 2027 route expansion and forms the core of the airline-focused update for SmartMarty Sky.

In addition to the Seattle expansion news, multiple outlets reported on a weather-driven diversion involving an Alaska Airlines flight operating from Dallas/Fort Worth to Seattle-Tacoma International Airport. The flight was diverted to Yakima, Washington, where a large group of passengers and crew—reported as about 127 to more than 130 people—spent the night at Yakima’s airport terminal or nearby areas. Multiple sources cited a weather disturbance over western Washington as the cause of the routing change that brought the aircraft to Yakima before rejoining its service plan, with the Yakima stop described as necessary to accommodate the disruption.

The aircraft in the Yakima diversion was identified as a Boeing 737 in several reports, and the diversion occurred as the flight approached Seattle and encountered unfavorable weather. The extended layover at Yakima was attributed in part to fueling procedures at Yakima International Airport, contributing to a longer-than-expected stop. The reports consistently describe the overnight stay as taking place at Yakima’s airport facilities, with ground handling continuing there rather than at Seattle that night, and the overall event described as weather-driven rather than an in-flight incident or mechanical failure.

NBC Bay Area contributed a parallel piece on a separate Alaska incident, describing an Alaska Airlines jet identified as Flight 528 that executed a sharp pull-up during its approach into San Francisco International Airport, resulting in an aborted landing or go-around after the flight encountered a second aircraft on or near the runway. NBC Bay Area framed the event as a runway situation that prompted federal scrutiny and a formal review process, rather than detailing any injuries or fatalities. Other outlets summarized NYC-area aviation events that day as unrelated to the Alaska incident.

The compiled material confirms that the weather-driven Yakima diversion involved passengers and crew who spent the night in Yakima, with various outlets noting the range of people affected (from 127 to more than 130). Ground handling and fueling delays at Yakima International Airport were cited as contributing factors to the prolonged layover, and the reports consistently specify the diversion originated on a Dallas/Fort Worth to Seattle route before routing to Yakima rather than proceeding to SEA that evening. The time and exact flight number from DFW to Seattle were not established in the material.

Beyond the Seattle-focused expansion and the Yakima diversion, the reporting set also includes details about Alaska Airlines’ proposed Anchorage–Tokyo Narita service. Simple Flying reported that Alaska is pursuing a seasonal, once-daily nonstop service from Ted Stevens Anchorage International Airport to Tokyo Narita, targeting a May 13, 2027 start date, subject to government approvals. The planned aircraft for this route is a Boeing 737 MAX 8, with an estimated flight time of about eight hours and 15 minutes. The material notes that regulatory approval is a prerequisite for launch, and no final launch date beyond the proposed May 2027 window is provided.

The Business Journals’ coverage, drawing on CBC and TravelPulse Canada-derived outlets, reinforces the Anchorage–Tokyo Narita plan, reiterating the MAX 8 equipment and the roughly eight-and-a-quarter-hour duration, while underscoring that regulatory clearance remains a prerequisite. CBC’s portion of the compilation adds a separate note about Porter Airlines’ winter schedule movements but does not provide further Alaska-specific operational details beyond the Anchorage–Tokyo Narita concept.

Overall, the collection of material presents Alaska Airlines pursuing growth from Seattle with five new U.S. city routes and a seasonal Guadalajara service for 2027, alongside a separate weather-driven Yakima diversion affecting a DFW-to-SEA flight and a distinct Alaska route proposal to Tokyo Narita from Anchorage. The sources consistently describe the Yakima stop as weather-related and the Tokyo Narita plan as contingent on regulatory approval, while not providing a final launch timeline beyond the targeted May 2027 window. The incident involving Flight 528 at SFO is characterized as under federal review with no reported injuries in the material.
