When Alaska Airlines talks about upgrading the “end-to-end experience,” it isn’t doing it in small ways. On Thursday, the airline confirmed its next big move at Seattle-Tacoma International Airport: a massive, higher-end lounge planned for the C Concourse that will open late 2027.
This won’t be a simple expansion of the existing Alaska Lounge formula. The new club is set to measure 41,000 square feet across two floors—described as Alaska’s biggest club yet. And while the first story will still have a more traditional Alaska Lounge setup. the second story is where the airline intends to separate premium travelers from the rest.
That top floor is designed for travelers flying long-haul flights in lie-flat seats. Alaska’s vision for the space is being compared to the highest tiers of other U.S. carriers’ premium lounges—such as United Airlines Polaris Lounge. American Airlines Flagship Lounge. or Delta One Lounge. including Delta’s lounge at SeaTac that opened last year.
The guest experience there is expected to include shower suites and a la carte-style dining. with Alaska CEO Ben Minicucci describing the lounge as something that leans into the airline’s Pacific Northwest ethos. Speaking to him last month in Rome. Minicucci said the facility will “cater to the true premium customers. ” adding: “If you’re going to charge for the [lie-flat] product. we want the entire end-to-end experience to be fantastic.”.
Access is also being tailored for Alaska’s and Hawaiian Airlines’ most frequent long-haul flyers. Top-tier Titanium elite members from Alaska and Hawaiian Airlines’ Atmos Rewards program will be able to enter the elevated space when flying long-haul.
For Alaska, this lounge is also a piece of a broader plan being built at SeaTac. Last month. the airline cut the ribbon on a luxe new check-in facility at SEA that includes a private entrance to the Transportation Security Administration checkpoint. With the premium lounge scheduled to open late next year’s timeframe. the company appears to be trying to complete the “ground” side of the premium journey for these travelers.
The timing matters. Alaska is building toward a global hub at SeaTac and plans to launch at least a dozen long-haul international routes from the airport by 2030 after previously operating only domestic and short-haul international service. Among those routes is a nonstop flight to Rome, which was taken for the trip described last month.
Service to London’s Heathrow Airport (LHR) begins Thursday. Alaska already operates nonstop service to Seoul and Tokyo.
The lounge plans also include a more inclusive option on the first floor. That traditional Alaska Lounge space on the first story will be accessible to anyone with an Alaska Lounge or Alaska Lounge+ membership. along with travelers who gain day access via the airline’s premium credit card. SeaTac currently has three standard Alaska Lounge locations. including an N Concourse outpost that is described as doubling as the go-to club for travelers flying internationally.
Even as the Seattle build moves toward its late 2027 opening, Alaska is already pointing to the next lounge upgrade. Before the new Seattle facility opens, the airline expects to unveil its newest outpost at Portland International Airport (PDX) this summer.

Late 2027… so basically not for anyone who’s flying this week. Cool, I guess.
41,000 square feet sounds huge but I swear every lounge is the same when you get in there. Lie-flat seats mean they’ll finally fix the bathroom situation? Like are the showers actually free?
Wait so this is in the C Concourse (like near security)? I’m confused because I thought Alaska already had their “premium” area at SEA. If they’re separating long-haul people on the second floor then how do they even decide who counts as “premium”? Sounds like a money grab but also maybe nice?
Every time Alaska says “end-to-end” I hear “more rules, fewer places to sit.” But shower suites and a la carte dining… that’s wild. I wonder if they’ll really let Hawaiian people in too or if it’s one of those like ‘eligible tier’ things that never feels eligible. Also why 2027, couldn’t they just update the old lounge like… now?
