About OC
OC is a regional carrier operating entirely within Japan, running 20 non-stop routes across 9 airports. With a total network spanning just 6,636 km, this is hyper-local flying — the kind of airline built to connect smaller communities rather than chase long-haul glory. Fukuoka (FUK) anchors the operation as the main hub, with five routes radiating outward. Nagoya, Nagasaki, and Tsushima round out the secondary hubs. Think short hops, domestic focus, and a route map that exists because trains and highways don't always cut it in island Japan.
Why fly OC?
The honest answer is convenience. If you're moving between places like Tsushima (TSJ) and the mainland, OC may be your only realistic option — and that alone makes it worth knowing. Regional carriers like this tend to operate on thinner competition, which means prices aren't always rock-bottom, but you're paying for access, not amenities. The FUK hub gives you a solid connection point if you're already routing through Fukuoka. Compared to burning a full day on surface transport, a short OC hop saves real time. For points travelers, I'd check whether your credit card travel portal can book these fares directly — that's often the cleanest play when frequent flyer programs aren't in the picture.

Tips for booking OC
Book early and check directly. Regional Japanese carriers don't always show up cleanly on global aggregators, so go straight to the source. The longest route in the network is FUK to KMQ at 627 km — short enough that you won't miss lie-flat seats, but pack light because regional aircraft typically have tight overhead storage. Don't expect lounge access or alliance benefits here. If you're connecting from a major carrier into FUK or NGO, build in buffer time — regional check-in processes can move slower than you'd expect. And confirm baggage allowances before you show up, because small carriers often have stricter weight limits than the big names.
