Checking in for your Jin Air flight, step by step

Jin Air's international conditions of carriage (revised 31 January 2025) devote a chapter to check-in and boarding, setting out check-in deadlines and boarding deadlines. These times depend on the departure airport and the destination, and the airline may deny carriage to a passenger who arrives after the deadline that applies to their flight.

The exact time that applies to you is the one printed on your Jin Air booking confirmation or displayed at the departure airport. Allow plenty of margin rather than cutting it close: during peak season at Incheon or Gimpo, bag drop and security queues get longer, and arriving late at the counter cannot be made up.

Online check-in, meanwhile, only opens during a limited window before departure: check the airline's official website for the opening and closing times that apply to your flight, since they are not the same across the whole network.

Jin Air offers online check-in on its official website and through its mobile app, as well as self-service kiosks at several Korean airports. The principle is the same everywhere: identify the booking with the reservation number or ticket number and the passenger's name, exactly as it appears on the passport.

Certain travellers still need to go through the counter, as is common with low-cost airlines: unaccompanied minors, passengers needing special assistance, women in late pregnancy, animals in the cabin, groups, tickets changed at the last minute, or destinations requiring a visa check. In these cases, online check-in may not go through and an agent will need to validate your booking on site.

If you are travelling with checked baggage, completing check-in in advance does not exempt you from going to the counter or the bag drop, which also closes before departure.

Once check-in is confirmed, the boarding pass is available as a mobile version in the app, sent by email as a PDF, or printed at the counter or a kiosk. Check that the name, date, flight number and gate match your booking, and keep the document accessible until you leave the arrival airport.

The mobile boarding pass is not accepted everywhere: some foreign airports served by Jin Air still require a paper version, particularly when immigration control or customs asks to see it. If in doubt, get your pass printed at the counter before going through the checks.

As for documents, bring a valid passport and, if required by the destination, a visa or electronic travel authorisation. Jin Air's conditions of carriage include a right to deny carriage, and incomplete travel documents are one of the common reasons for being turned away at check-in.

Jin Air runs on a low-cost model: the checked baggage allowance depends on the fare purchased and the route, and any excess is charged as a supplement. Cabin items are also limited in number, size and weight under the airline's conditions of carriage; weigh and measure your cabin bag before departure, as checks at the boarding gate are frequent.

A few points worth sorting out during check-in rather than at the last minute:

• seat selection or purchase, including extra legroom seats, which are often paid options;
• buying extra baggage allowance, best checked on the airline's official website, since prices can differ between advance purchase and the airport;
• declaring a musical instrument, sports equipment or an animal, which requires prior approval;
• lithium batteries and items forbidden in checked baggage, to be removed from your case before bag drop.

If you can no longer find your boarding pass, if your name was entered incorrectly, or if online check-in will not go through, head to the Jin Air counter as soon as you reach the airport: a name correction or a visa check takes time. To avoid having to watch for check-in to open, you can hand your check-in over to iBoardingPass, which completes it as soon as it opens and sends you your boarding pass by email.
