About LJ
LJ is Jin Air, a Korean low-cost carrier that operates out of Seoul's Incheon (ICN) and a handful of other Korean hubs. Think budget flying with a distinctly Northeast Asian flavour — the kind of airline that fills seats between Korea and Japan on a Tuesday afternoon and gets you to Phu Quoc cheaper than you'd expect. With 112 non-stop routes spread across 39 airports, it's not tiny, but it's not trying to rule the world either. The network leans heavily domestic and regional, which is exactly what a budget carrier should do well.
Why fly LJ?
Honestly, the main reason to fly Jin Air is price. If you're positioning through ICN — which, if you travel Asia regularly, you probably are — Jin Air can slot into your itinerary in a way that saves real money compared to full-service options. Seventeen routes into Japan is solid coverage for a budget carrier, and the Phu Quoc (PQC) to Seoul run at 3,775 km shows it's not just hopping between nearby islands. The Philippines and Taiwan coverage also means it's a legitimate option for building a Southeast Asia loop without constantly switching carriers. Service is functional and no-frills, which is fine when the price is right.

Tips for booking LJ
Baggage is where budget carriers get you, and Jin Air is no different — check your fare class before assuming anything is included. The Busan (PUS) hub is worth knowing about if you're already in southern Korea; 18 routes out of there gives you real options without backtracking to Seoul. GMP, Seoul's domestic airport, only has 5 routes, so don't assume you can connect everything through there. Book direct through Jin Air's site for the best fare visibility, and if you're doing a visa run circuit through Japan or Taiwan, the frequency on those corridors makes it pretty convenient.
