44 non-stop routes across 15 airports. Main hub: Ketchikan (KTN).

About K3

K3 is a regional carrier built entirely around the remote communities of southeastern Alaska, and it makes no apologies for that focus. With 44 non-stop routes spread across 15 airports, all of them domestic, this is an airline shaped by geography rather than commercial ambition — the kind of operation that exists because roads often don't. Ketchikan's airport (KTN) anchors the network with 13 routes radiating outward, connecting a coastline where floatplanes and small aircraft aren't a novelty but a practical necessity for daily life.

Why fly K3?

If you're heading into the deeper reaches of the Alexander Archipelago, K3 may simply be your only option — and that's worth understanding before you start comparing prices. Thorne Bay (KTB) and Edna Bay (EDA) are not places you reach by interstate. The fact that K3 serves these communities at all is the point. For travelers with genuine curiosity about Alaska beyond the cruise-ship ports, this network opens up fishing villages, old-growth forest communities, and coastline that most visitors never see. The longest route in the system, KPB to KTN at 163 kilometers, gives you a sense of scale — these are short hops, but they cover terrain that would otherwise take hours by water.

Tips for booking K3

Book early if your travel dates are fixed — small regional carriers on thin routes don't have spare capacity to absorb last-minute reshuffling. Connections through KTN are worth building extra time around, since weather in southeastern Alaska moves fast and departure windows can shift. Pack light and practically; luggage policies on aircraft serving remote Alaskan strips tend to be strict on weight, so check allowances carefully before you arrive. Don't expect the amenities of a mainline carrier — no lounges, no frequent-flyer miles worth chasing. What you get instead is access, which on these routes is worth considerably more.
