About the Daegu → Jeju route
Daegu to Jeju is about as domestic as domestic gets — 330 km, roughly 23 minutes in the air, and you'll spend more time taxiing than cruising. Five carriers operate this route (KE, OZ, LJ, 7C, and TW), which tells you something useful: there's enough demand here to keep the low-cost carriers honest and the full-service options competitive. This is overwhelmingly a leisure route. Daegu residents heading to Korea's favorite island escape aren't interested in business-class upgrades — they want to get there fast and spend the money on black pork and rental cars instead.
Why travel from Daegu to Jeju?
Jeju earns its reputation the old-fashioned way. The island's volcanic — including Hallasan, the highest peak in South Korea — draws hikers who want something genuinely dramatic, not just a gentle trail. The eastern coastline around Seongsan Ilchulbong is worth the trip alone, a tuff cone rising straight out of the ocean that looks slightly unreal at sunrise. For Daegu travelers specifically, Jeju also means seafood that doesn't come from a tank on a city street — haenyeo divers still bring up fresh abalone and sea urchin daily. Families come for the beaches in summer, couples come for the slow pace year-round, and anyone who's tired of mainland Korea's density comes for the breathing room.

Practical tips for TAE → CJU
Avoid July and August unless you enjoy crowds that make Gimpo Airport look spacious — Jeju gets overwhelmed in peak summer. Spring (April to May) and autumn (September to October) offer better weather and meaningfully lower fares, especially on LJ or 7C where the base price already assumes you're packing light. Seriously, check your baggage allowance on low-cost carriers before you print that boarding pass. CJU arrivals are straightforward — the airport is compact and taxis are metered and reliable. Limousine buses cover most resort areas cheaply. No visa issues for Korean nationals, and the island uses Korean Won throughout.
