Jin Air

Jin Air is the low-cost airline of the Korean Air group, flying from Seoul, Busan and Jeju to Japan, China, Southeast Asia and Pacific islands. Cabin bags are usually up to 10 kg, most fares include 15 kg of checked baggage, and power banks cannot be used on board. This guide covers the Korean power bank ban, check-in, the planned merger with Air Busan and Air Seoul and how it compares with its Korean rivals.

Founded in 2008, the airline flies Boeing 737 aircraft. After Korean Air’s merger with Asiana, the airline will absorb Air Busan and Air Seoul to become Korea’s largest low-cost airline.

Power Bank Rules on Jin Air

All South Korean airlines now ban the use of power banks on board:

• You cannot charge devices from a power bank or charge the power bank itself during the flight.
• Keep power banks within reach, not in the overhead bins, with the terminals taped or in a plastic bag.
• Power banks must be in cabin baggage; up to 100 Wh needs no approval and 100–160 Wh needs approval.

Check-In in Seoul

Online check-in is available on the website and app, and self bag drop is available at Incheon. Counters close 50 minutes before international flights, so arrive at least two hours early.

Families and Special Assistance

Infants under two travel on an adult’s lap. Request wheelchairs and other special assistance at least 48 hours before the flight.

The Korean Low-Cost Merger

Korea’s low-cost market is changing:

• The three Korean Air group low-cost airlines plan to merge under one name, expected on 17 March 2027.
• Bookings on the three airlines should be honoured during the change.
• The merged airline will have a larger network from Seoul and Busan.

Is Jin Air a Good Airline?
