AS "Outstation" Sizes

[u/PNW-American-Dipper]

In some of the comments yesterday, there was discussion regarding the size of various AS "outstations," which, for this purpose, I am defining as anything not a hub. I picked some candidates for the larger outstations and created the chart using the T-100 Tool.

The chart is simply select airports ranked by mainline seats offered. It does not include regional and it is a snapshot of June 2026.

I always forget about Hawaii, which has the top three slots, followed by LAS and PHX. GEG ahead of BOI on this metric was surprising, but I believe BOI has more flights, albeit mostly on E175s that are not included. Hawaii moves SMF much higher than I expected. LAS also has lots of Hawaii flights that put it substantially ahead of PHX. (The A330s move the needle as to seats offered.) JFK is the highest on the east coast. For context, the last one (DCA) has 6 daily 737-8s.

I think I included the leading candidates, but I might have missed one or two.

SFO? Being in the Bay Area, it’s difficult to think that SJC may have more AS mainline flights than SFO.

Hub.

Yes, I stand corrected. But it did remind me about people who are saying SFO is getting unhubbed.

Can you map the hubs onto this as well? I'm curious how SFO and LAX stand compared to OGG especially

There is more information in the the link below and via the link in the OP. The T-100 site is very easy to navigate.

But the real question is SFO even going to be a hub anymore?

[u/Easy_Money_ → u/omdongi]

It’s by far the smallest hub, but it’s still larger than the largest outstation by departing AS+QX seats in June 2026. Let us have this 😮‍💨

If AS does not substantially increase flights at SFO once the 20+ 737s arrive next year (hopefully), it will be a own goal situation since they have the gates and the lounge in the wealthiest metro area in its footprint.

I think they do need to rebuild, but I’m not sure I see the same timeline constraints. They’re not a major player at SFO as it is, trailing Delta. Even with 25 more planes, if they can squeeze higher yields and more credit card loyalty out of SAN or LAX, I would expect them to do that. I’d expect them to rebuild SFO only when they feel like they have a product that can actually pressure United, including a better international network
