About HD
HD is a regional Japanese carrier operating a tight domestic network built around Hokkaido and the main islands of Japan. With 22 non-stop routes connecting 11 airports, this is an airline that knows its lane — it's not trying to fly you to Bangkok or Los Angeles. The whole operation stays within Japan, which tells you a lot about the business model: short hops, high frequency, local demand. HND is the main hub with six routes, but Sapporo's CTS airport is close behind at five, making Hokkaido clearly central to what HD does.
Why fly HD?
If you're moving around northern Japan — particularly between Hokkaido and the rest of the country — HD fills gaps that bullet trains either can't reach or make genuinely inconvenient. The longest route, FUK to CTS at 1,416 km, is a solid example: flying that saves hours compared to any surface alternative. For travelers focused on Hokkaido specifically, having a carrier that treats CTS and HKD as real hubs rather than afterthoughts is actually meaningful. You're not routing through Tokyo just to get somewhere that's geographically closer to Sapporo. That kind of logical routing is underrated, and frequent travelers to the region will feel it immediately in saved time and simpler connections.

Tips for booking HD
Book directly and check whether your fare includes checked baggage — regional carriers in Japan often strip that out at the base price. HND is HD's biggest hub, so if you're connecting from an international flight into Tokyo, that's your most reliable entry point into the network. CTS is worth knowing too; Sapporo's airport is well-connected within HD's system and often cheaper to fly into than you'd expect. The network covers 20,074 km total but stays entirely domestic, so don't look for international codeshare shortcuts here. First-time flyers should set expectations accordingly — this is a point-to-point domestic operation, not a full-service carrier with lounges and loyalty complexity.
