About 7C
7C is Jeju Air, South Korea's original low-cost carrier — and honestly one of the more interesting budget airlines operating in Northeast Asia right now. Built around ICN as its main hub, it punches well above its weight for a regional LCC, running 124 non-stop routes across 50 airports. The network leans heavily domestic and intra-Asian, with Korea, Japan, and China making up the bulk of destinations. Don't expect alliance perks or lie-flat seats. This is point-to-point flying, priced to move, aimed squarely at travelers who'd rather spend money on the ground than in the air.
Why fly 7C?
The honest case for 7C comes down to route access and price. If you're moving around Northeast Asia — particularly between South Korea and Japan, which accounts for 16 routes — Jeju Air frequently undercuts the legacy carriers by a meaningful margin. The ICN hub alone covers 39 routes, which gives you solid onward options whether you're island-hopping toward the Philippines or heading into China. The longest route, DPS to ICN at 5,270 km, shows the airline isn't purely a short-haul operation either. For budget-conscious nomads doing visa runs or regional loops, this kind of reach matters. It's not glamorous flying, but it gets you there without wrecking your monthly budget.

Tips for booking 7C
Book direct through Jeju Air's site — third-party platforms sometimes miss fare sales. Baggage is almost never included on base fares, so price that in before you assume you're getting a deal. The PUS hub in Busan is worth knowing about if you're already in the south of Korea and want to avoid the ICN schlep. CJU serves as a decent domestic connector for Jeju Island routes. Fare classes vary, and flexibility costs extra, so if your plans might shift, pay attention to what you're actually buying. First-timers should check-in online early — seat selection fees add up fast if you leave it to the gate.
