As of 2026, Bellingham International Airport (BLI) is primarily served by Alaska Airlines, Allegiant Air, and San Juan Airlines. These carriers provide a strategic mix of daily regional connections to major hubs, ultra-low-cost direct flights to leisure destinations across the Sun Belt, and essential commuter links to the San Juan Islands.
Bellingham International Airport (BLI) has solidified its reputation as a preferred alternative to the larger, more congested hubs of Seattle-Tacoma International (SEA) and Vancouver International (YVR). For travelers residing in Whatcom, Skagit, and Island counties—as well as those crossing the border from British Columbia—the airport offers a streamlined, efficient experience. By 2026, the airport has maintained its status as a vital economic engine for the Pacific Northwest, balancing local commuter needs with high-volume seasonal tourism.
Alaska Airlines: The Gateway to the Global Network
Alaska Airlines remains the cornerstone of legacy service at Bellingham International. Operating primarily through its regional subsidiary, Horizon Air, Alaska provides frequent daily flights that connect Bellingham to the rest of the world.
Connecting via Seattle-Tacoma (SEA)
The primary route offered by Alaska Airlines from BLI is the short hop to Seattle-Tacoma International Airport. This flight, typically lasting between 40 and 55 minutes, is the primary lifeline for business travelers and international vacationers. From the Seattle hub, passengers can access Alaska’s extensive domestic network and the broader oneworld® alliance, which includes partners like American Airlines, British Airways, and Cathay Pacific.
In 2026, these flights are predominantly serviced by the Embraer 175 (E175) jet. The E175 is favored for this route because it offers a three-class configuration—First Class, Premium Class, and Main Cabin—ensuring that the "mainline" experience begins the moment a passenger boards in Bellingham. Unlike the turboprops of the past, these jets offer a quieter cabin and no middle seats, a significant selling point for local travelers.
Loyalty and Logistics
For frequent flyers, the Mileage Plan program is a major draw. Passengers flying out of Bellingham earn full miles that count toward elite status. Additionally, Alaska Airlines offers a "Wine Flies Free" program for Mileage Plan members on certain West Coast routes, although this is more common on flights departing from regional wine hubs.
When flying Alaska from BLI, check-in is located at the southern end of the terminal. Because BLI is a smaller facility, the transition from the check-in desk through TSA security to the departure gates (usually Gate A or B) is remarkably fast, often taking less than 20 minutes outside of peak holiday windows.
Allegiant Air: The Low-Cost Leisure Specialist
Allegiant Air is the largest carrier at Bellingham International by destination count. Their business model focuses on "point-to-point" service, connecting smaller cities like Bellingham directly to popular vacation spots without the need for a layover in a major hub.
Current 2026 Destinations
Allegiant’s schedule is highly seasonal, reflecting the travel habits of Pacific Northwest residents seeking sun during the rainy months. As of 2026, regular direct destinations from BLI typically include:
- Las Vegas, NV (LAS): A perennial favorite with near-daily service.
- Phoenix/Mesa, AZ (AZA): Serving the Valley of the Sun, primarily through the Phoenix-Mesa Gateway Airport.
- Oakland/San Francisco, CA (OAK): Providing access to the Bay Area.
- Los Angeles, CA (LAX): Frequent service to the heart of Southern California.
- San Diego, CA (SAN): Popular for family vacations and military travel.
- Palm Springs, CA (PSP): Usually offered as a seasonal winter route (October through May).
The Allegiant Service Model
Allegiant operates as an ultra-low-cost carrier (ULCC). This means their base fares are often significantly lower than legacy competitors, but they utilize an unbundled pricing model. Passengers should be prepared for additional fees for:
- Carry-on bags and checked luggage.
- Seat assignments.
- In-flight refreshments (water and snacks).
- Priority boarding.
In 2026, Allegiant has integrated more of the Boeing 737 MAX aircraft into its fleet serving Bellingham, replacing older Airbus models on certain high-demand routes. These newer aircraft offer better fuel efficiency and slightly updated cabin interiors. Travelers are encouraged to use the Allegiant mobile app for digital boarding passes, as printing a pass at the airport counter often incurs a convenience fee.
San Juan Airlines: The Regional Lifeline
While the major carriers focus on the mainland, San Juan Airlines provides an essential service for locals, tourists, and property owners in the nearby archipelago. This is a "commuter" or "bush" airline experience that operates out of the general aviation side of the airport or specific commuter gates.
Routes and Charters
San Juan Airlines offers scheduled flights from Bellingham to:
- Friday Harbor (San Juan Island)
- Eastsound (Orcas Island)
- Lopez Island
- Roche Harbor
These flights are typically operated using small, high-wing aircraft like the Cessna 207 or Cessna 172. The flight time is usually under 20 minutes. Beyond scheduled flights, they are the primary provider of point-to-point charters throughout the Pacific Northwest and British Columbia.
Why Choose the Air over the Ferry?
For many, the choice to fly San Juan Airlines is a matter of time management. The Washington State Ferry system, while scenic, often faces significant delays, reservation shortages, and long transit times from the Anacortes terminal. Flying from BLI allows travelers to bypass the drive to Anacortes and the ferry wait entirely, making it possible to reach Friday Harbor from Bellingham in a fraction of the time.

The Canadian Factor: Why BLI is "Vancouver South"
A unique aspect of Bellingham International Airport is its heavy usage by Canadian citizens. Located just 20 miles south of the Peace Arch border crossing, BLI serves as a secondary airport for the Lower Mainland of British Columbia.
Cost Savings for Canadians
The primary driver for Canadian travelers is cost. Flights originating in the United States do not include the high international taxes and airport improvement fees (AIF) typically found at Vancouver International (YVR). For a family of four flying to Las Vegas or Orlando, the savings by driving across the border and flying out of Bellingham can often exceed $500–$800.
Border Logistics in 2026
In 2026, savvy travelers monitor border wait times via the Washington State Department of Transportation (WSDOT) or official Canadian border services apps. It is generally recommended to allow an additional two hours of "buffer time" during peak weekend travel periods to account for potential delays at the Peace Arch or Pacific Highway crossings.
Airport Amenities and Terminal Logistics
Bellingham International is a single-terminal airport, which simplifies the travel process. However, its small size means that amenities are focused on quality rather than quantity.
Parking Options
Parking at BLI is divided into three main categories:
- Hourly/Daily Lot: Located directly across from the terminal. Best for short trips or picking up passengers.
- Economy Lots (A and B): Located within walking distance or a short shuttle ride. These are the most cost-effective for long-term stays.
- Off-Site Parking: Several private lots near the airport offer competitive daily rates with shuttle service to the curb.
In 2026, the airport has expanded its electric vehicle (EV) charging stations in the main daily lot to accommodate the growing number of local travelers using electric transport.
Dining and Security
Post-security, passengers have access to Halibut Henry’s, a local favorite offering coffee, snacks, and Northwest-themed souvenirs. There is also a sit-down cafe and bar area that serves local craft beers—a staple of the Bellingham culture.
The TSA checkpoint at BLI supports TSA PreCheck. Because of the airport's layout, there is no dedicated "Clear" lane as of 2026, but the standard and PreCheck lines are rarely long enough to necessitate one.
Historical Context: The Departure of Southwest Airlines
Readers looking for Southwest Airlines should note that the carrier ended its service at Bellingham International in August 2024. While Southwest's entry into the market in 2021 initially brought increased competition and lower fares to Denver and Oakland, the airline eventually exited the market due to broader fleet constraints and a shift in their regional strategy. As of 2026, Southwest has not announced a return to BLI, leaving Allegiant as the primary provider of low-cost direct flights to the Southwest United States.
Frequent Questions Regarding BLI Airlines
Does Delta or United fly out of Bellingham?
As of 2026, neither Delta Air Lines nor United Airlines operates direct flights out of Bellingham. Travelers who prefer these carriers typically fly Alaska Airlines to Seattle-Tacoma (SEA) and transfer, or they drive to Vancouver (YVR) or Seattle (SEA) to catch direct flights.
How early should I arrive for a flight at BLI?
For domestic flights on Alaska or Allegiant, arriving 90 minutes before departure is generally sufficient. If you are checking bags with Allegiant or traveling during a major holiday (such as Thanksgiving or Christmas), arriving two hours early is recommended to ensure you clear the bag drop and security.
Are there international flights from Bellingham?
Bellingham International does not currently offer scheduled commercial international flights to destinations outside the U.S. (with the exception of some San Juan Airlines charters to British Columbia). Despite its name, the "International" designation primarily refers to its ability to handle customs for private aircraft and its proximity to the border.
What is the best way to get from Vancouver, BC to BLI?
Most travelers from Canada drive and park their vehicles at the airport. However, the Quick Shuttle service continues to provide bus transportation between downtown Vancouver/Richmond and Bellingham International Airport. Additionally, some travelers use the Amtrak Cascades to the Fairhaven Station in Bellingham and take a short rideshare to the airport.
Can I fly to Hawaii from Bellingham?
Direct flights to Hawaii are not currently offered from BLI in 2026. Travelers wishing to visit Hawaii typically fly to Seattle via Alaska Airlines and connect to a direct flight to Honolulu, Maui, or Kona. Occasionally, Allegiant has explored Hawaii routes from the West Coast, but these have not historically operated out of Bellingham due to runway and aircraft range considerations.
Expert Recommendation for Travelers
If you are booking a flight from Bellingham in 2026, download the airline's mobile app immediately. Both Alaska and Allegiant have moved toward a digital-first model where gate changes, baggage tracking, and boarding passes are handled via smartphone. For those seeking the best value, Allegiant’s "Bundle" options (like Allegiant+ or Allegiant Total) often prove cheaper than adding a carry-on bag and seat selection separately at the end of the checkout process.
