Jin Air (LJ) is the low-cost subsidiary of Korean Air, flying domestic Korean routes plus a network across Japan, China, Hong Kong, Macau, Taiwan, Southeast Asia, Guam and the US territories. Unlike the strictest ultra-low-cost carriers, Jin Air still bundles a free checked allowance into most fares — but the exact weight and piece count varies significantly by route
The headline rule: one carry-on up to 10 kg plus a personal item, and a free checked allowance that is 15 kg on domestic and most international routes, 20 kg (1 piece) on Mainland China routes, and a generous 2 pieces × 23 kg on USA and US-territory routes (including Guam). Anything beyond that is bought by the kilo, and it is always cheaper prepaid online than at the airport.

| Weight limit | 15 kg / 20 kg / 23 kg depending on route (single-bag piece limit applies; check route specifics) |
| Typical fee | Excess sold in 5 kg increments — prepaid online is meaningfully cheaper than buying at the airport. International excess rose by roughly KRW 5,000 per 5 kg (domestic ~KRW 2,000) in a July 2024 fee revision, and Korean LCCs raised fees again into 2025–26. |
What each fare includes
| Fare | Personal | Cabin | Checked |
|---|---|---|---|
| Standard fare | 1 under-seat item | 10 kg carry-on + personal item | Free allowance per route (15 kg / China 20 kg / USA-Guam 2×23 kg) |

What you actually get on a cheap fare
What you actually get at deal prices: Jin Air is more generous than most ultra-low-cost carriers — even its cheapest tickets typically include a 10 kg carry-on plus a checked bag. On the routes aifly tracks, the base fare bundles roughly 1 × 15 kg checked on most international/domestic sectors, stepping up to 20 kg on Mainland China and a standout 2 × 23 kg on USA/Guam routes.
That means on a typical Jin Air deal you rarely need to pay extra to check a normal-sized suitcase — a real advantage over Jeju Air, T’way or the big-three European LCCs where a checked bag is always a paid add-on. If you pack heavy, buy the extra 5 kg online rather than at the gate; the airport gap is steep.
Oversize, sports & special items
Oversize & overweight: Single checked bags are subject to a per-piece weight cap and a linear-dimension limit; pieces over the cap are charged as oversize/overweight and may need to be tendered at a dedicated counter. Confirm the exact thresholds for your route when booking.
Sports & special equipment: Jin Air sells dedicated golf packages — Golf Pack Basic around KRW 70,000 / USD 70 and Golf Pack Special around KRW 86,000 / USD 86 (Special is limited and first-come, first-served). The Golf Pack can be bought by anyone, not only golfers. Other sports gear (skis, bikes, surfboards) is carried as oversize baggage subject to fees and packing rules.
Buying extra: Prepaid excess baggage can be purchased online or via the call centre up to 24 hours before departure, in fixed weight units (commonly 5 kg), at rates below airport excess pricing.
