Alaska Airlines is going global, but can Seattle support it? We break down the load factors, hub strategy, and what’s at stake for their international network.
Alaska Airlines’ first Boeing 787 Dreamliner flight from Seattle to Rome kicked off last week. It gained a lot of fan fare on FlightRadar24’s Instagram. That kind of consumer excitement signals something real. Alaska is no longer a regional carrier playing West Coast-only operations.
Since their acquisition of Hawaiian Airlines, the airline has expanded to Europe and international destinations throughout Asia, transforming from a West Coast-only operation into something that looks increasingly like a national and international player.
But here’s a question…is the foundation they’ve built strong enough to support their international ambitions?
Let’s analyze the case for and against that notion.
Alaska’s hub structure tells you everything about their operational strategy. Their hubs are concentrated entirely on the West Coast: Seattle, Anchorage, San Francisco, Los Angeles, Portland, and San Diego.
| Airport | Alaska’s Market Share % | Next Largest Carrier Market Share |
| Seattle | 47.85% | Delta – 19.49% |
| Anchorage | 61.89% | Delta – 13.57% |
| Portland | 32.5% | Southwest – 13.28% |
Seattle is without a doubt their super hub, where the bulk of their high-yield route pairs and international flying originates. Their California hubs focus primarily on Hawaii flying, leisure flights down to Mexico and with some transcons sprinkled in.
Their reliance on San Francisco and Los Angeles has slightly begun to diminish, as those airports are notably difficult to remain competitive in, relatively speaking against United and Delta. More recently, Alaska has been growing operations at nearby San Diego instead. But ultimately, the goal of these California hubs is to help flow more customers towards Seattle.
Alaska is one of the only airlines to geographically isolate their hubs to a single coast. Delta, United, and American have a presence in major cities throughout the United States. Southwest and Frontier, despite not officially labeling their core cities as hubs, maintain a footprint at large airports across the country.
The only relatively large airline that mirrors this strategy is JetBlue. They’ve largely scaled back their West Coast presence when they dropped Long Beach in favor of Los Angeles. But now primarily focus much of their flying on the East Coast, like when they first started.
JetBlue is navigating their own issues of mixed brand identity, caught between East Coast flying, low-yield Latin American routes, and transatlantic ambitions. While the geographic concentration strategy is similar to both airlines, Alaska is executing the strategy considerably better. JetBlue, by contrast, is reportedly on the brink of bankruptcy partially due to their own brand confusion.
| Airline | Hubs | East Coast | Midwest | West Coast |
| Alaska Airlines | ANC,LAX,PDX,SAN,SFO,SEA | 0 | 0 | 6 |
| American Airlines | CLT,ORD,DFW,LAX,MIA,LGA,PHL,PHX,DCA | 5 | 2 | 2 |
| Delta Air Lines | ATL,BOS,DET,LAX,MSP,JFK,LGA,SLC,SEA | 4 | 2 | 3 |
| United Airlines | ORD,DEN,IAH,LAX,EWR,SFO,IAD | 2 | 2 | 3 |
| Frontier Airlines | ATL,DEN,PHL,LAS,DFW,MCO | 3 | 1 | 2 |
| JetBlue Airways | BOS,FLL,JFK,MCO | 4 | 0 | 0 |
| Southwest Airlines | MDW, BWI, DAL, LAS, BNA, PHX, MCO, SAN, DEN | 3 | 2 | 4 |
| Allegiant Air | LAS, AZA, SFB, | 1 | 0 | 2 |
| Sun Country Airlines | MSP | 0 | 1 | 0 |
This West Coast only strategy has been working for Alaska for a long time. But the core question of this analysis is whether that geographic isolation is leaving revenue or potential customers on the table, specifically when it comes to their overseas intercontinental operation.

One of the main benefits of building a network around Seattle is that virtually every high yield connecting flight into SEA is a lengthy flight. That distance alone creates a natural opportunity to market premium cabin arrangements and convert passengers into Mileage Plan members. That recurring loyalty income matters a lot especially in today’s airline market.
Those premium loyalty miles earned on transcontinental flying feed directly into Alaska’s international product. Loyal Alaska customers accumulate points on those long domestic legs, and suddenly a trip to Rome using Alaska doesn’t seem like a stretch. Miles can lead to perks or shave a few dollars off the fare. International routes depend heavily on premium cabin revenue to stay profitable, and Alaska’s domestic network is quietly building the customer base that sustains it.
Seattle, for all its strengths as Alaska’s fortress, has a geography problem. It sits in the Pacific Northwest and it is not Los Angeles, and it is not Chicago. The local population base it draws from is significantly smaller than the mega-hubs Delta and United operate from.
| City | 2020 Census Population | Tourists visited |
| Seattle | 737,015 | 39.6 million (2025) |
| Los Angeles | 3,898,747 | 49.1 million (2023) |
| Chicago | 2,746,388 | 55 million (2025) |
| New York City | 8,804,190 | 65 Million (2025) |
Pacific Northwest residents will naturally funnel through Seattle using Alaska out of convenience. But outside that region, West Coast travelers tend to gravitate toward LAX, SFO, or even Phoenix for their international connections. Alaska knows this, which is why Seattle relies heavily on connecting traffic to feed its operation.
On a more national scale, you’re asking loyal Alaska Airline travelers from Boston, Atlanta, or Chicago to connect through Seattle to reach a destination they could access more directly on Delta from JFK or United from O’Hare. The inconvenience compounds, and Alaska’s price advantage or premium perk package has to work harder to compensate. No customer in their right mind wants to double-back just for the fun of it.
However, it appears that Alaska has already solved the international flight dilemma for their East Coast travelers.
Alaska’s Oneworld membership provides a partner network at key East Coast international gateways. Most notably JFK, where Alaska has gone as far as building an Atmos lounge despite operating only a handful of their own flights there.
They’re leaning on Oneworld partners who already have a robust schedule from that airport rather than competing for gates directly or committing their own aircraft on routes. Given how expensive and difficult gate access is at major East Coast airports, it’s a smart allocation of resources.
Alaska’s international product itself has also taken a meaningful step forward. The new cabin experience on the 787 Dreamliner, combined with the Airbus A330s inherited from Hawaiian Airlines, gives Alaska a competitive widebody product they simply didn’t have ever before.
A baseline Dreamliner delivers an experience that is genuinely comparable to what United, American, or Delta offer on similar long-haul routes.

While much of this analysis has focused on the challenges of flying eastward toward Europe, Alaska’s Pacific routes deserve their own attention, because the data is encouraging.
It’s long been known that United and Delta both dominate transoceanic flights from the United States. American simply doesn’t offer the volume of Asia service that either carrier does, leaving a meaningful gap in the market. Alaska has a real opportunity to step into that space.
Based on BTS data, Alaska is holding their own.
| Airline | Route | Departures | Seats | Passengers | Load Factor |
| Alaska | SEA – NRT | 62 | 18358 | 12832 | 69.8% |
| Alaska | SEA – ICN | 46 | 13900 | 8571 | 62.1% |
| Delta | SEA – ICN | 64 | 18961 | 13428 | 70.8% |
| United | SFO – NRT | 62 | 17369 | 13245 | 76.2% |
Alaska’s cornerstone routes between Seattle, Tokyo, and Seoul are performing on par with what Delta and United are currently running on directly comparable flights. The passenger counts, seat capacity, and load factors are competitive. That’s not a small thing for an airline that is still relatively new to this space.
Europe still presents more questions than answers due to the sheer fact that the service just started. The Rome launch is exciting, but it’s one route. But there’s more coming. Iceland and London are starting up in a few days.
Alaska’s Pacific operation already has some legs to it. Which is great for Alaska Airlines to be confident about when it comes to their international product.
For now, their West Coast strategy remains the clearest path forward for their international service.
Alaska has the product. The honest question is whether Seattle’s metropolitan area, even with robust connecting traffic, can generate the demand needed to scale their international network the way the airline clearly intends to. Which it likely can, evidenced by their success in the Asia market so far.
But Delta isn’t standing still in Seattle. Southwest has moved into Anchorage. The competitive pressure on Alaska’s home turf is real and arriving from multiple directions simultaneously.
The Rome launch is an exciting opening move. But one flight being hyped on FlightRadar24 tells you about enthusiasm, not load factors. That’s the number worth watching.
