Quick answer

You cannot fully book a Korean Air unaccompanied minor (UM) flight online — you must arrange it by phone (or at a ticket office) so the airline can confirm an escort slot, record both guardians’ details, and attach UM service to the ticket. Call +1 (888) 217-2892 (24/7) to book and add UM service in one call. Children under 5 can’t fly alone; UM service is mandatory for ages about 5 to under 12 on international flights and optional for ages 12–17. Fees are typically about $100–$150 each way on long-haul international routes, on top of the airfare. Korean Air’s official line 1-800-438-5000 handles flight status, refunds, baggage, and check-in.

What is Korean Air’s Unaccompanied Minor (UM) service?

It’s a paid escort program for children flying without a parent or qualifying adult. Trained staff help the child at check-in, through security to the gate (with a guardian gate pass), during boarding, in flight, and at arrival — where the child is released only to the pre-named guardian with matching photo ID. Most U.S.–Asia UM trips connect through Korean Air’s hub at Incheon International Airport (ICN), a major SkyTeam gateway. UM service is available in all cabins, including Prestige Class. Note that cabin crew check on the child and assist with meals and comfort, but do not provide constant one-on-one supervision.

Korean Air unaccompanied minor age rules (2026)

Age is based on the child’s age on the travel date. Confirm specifics for your route when booking, as cutoffs can vary slightly by country and connection type.

Child’s age (on travel date)	International flights	Domestic (within Korea)
Under 5	Not accepted alone — must travel with an adult (18+)	Not accepted alone
About 5 to under 12	UM service required	UM service required (commonly under ~13)
12 to 17	UM service optional (parents may request it)	Optional
18+	Treated as an adult	Treated as an adult

 

The accompanying adult, when one is required, generally must be 18 or older — so a 16-year-old sibling cannot serve as the escort. For ages 5 to under 12 on international routes, UM service is mandatory and cannot be waived.

Why you have to call to book (it can’t be done fully online)

Korean Air’s online engine doesn’t support completing a UM reservation. A phone call is required because:

• Escort capacity is limited — only a set number of UMs are accepted per flight, so a slot must be confirmed.
• Guardian information must be collected for both the drop-off and pick-up adults (names, addresses, phones, ID).
• Korean Air must prepare the UM “Handling Advice” form tied to the booking.
• The UM service fee is added manually, separate from the airfare.
• Connection rules must be reviewed — some connecting or late-night itineraries aren’t allowed for minors.

Book the ticket and UM service together — call +1 (888) 217-2892 (24/7).

 

How much does Korean Air charge for an unaccompanied minor?

The UM service fee is charged separately from the airfare, and the child is generally booked in an eligible adult-level fare (not a child discount). Fees depend on route and segment. The figures below are typical estimates — confirm the exact amount for your itinerary when you call.

Route type	Typical UM service fee (each way)
Long-haul international (U.S. ⇄ Seoul/ICN)	About $100–$150 USD per direction
Shorter international / regional	About $50–$100 USD
Domestic (within Korea)	Lower regional fee (varies)

 

Fees are charged per direction and sometimes per flight segment on connecting itineraries. Siblings traveling together may be covered by a single fee — confirm at booking. Fares and fees change and vary by route and season.

How to book a Korean Air unaccompanied minor flight, step by step

1. Gather your information first

Child’s full legal name (as on passport), date of birth, and passport details; preferred nonstop flights; and full details for the departure and arrival guardians (name, address, phone, relationship, ID).

2. Call to book the ticket + UM service

Call +1 (888) 217-2892 (booking help) or 1-800-438-5000 (Korean Air official). State the child’s exact age and that you need Unaccompanied Minor service; the agent confirms escort availability, books an eligible fare, adds the UM fee, and records guardian details.

3. Choose nonstop flights

Nonstop is strongly preferred. Korean Air may restrict UMs on certain connections, overnight layovers, or the last departure of the day to avoid a child being stranded.

4. Submit the UM request early (24–48 hours ahead)

Request and confirm UM service well before departure — escort slots can fill, and last-minute requests may be denied.

5. Pay and save your confirmation

Pay the airfare plus the UM service fee and keep your booking reference and any UM paperwork the airline sends.

6. On departure day

Arrive 2–3 hours early, check in at the Korean Air counter as a UM, complete the Handling Advice form, get a gate pass to escort the child to the gate, and stay at the airport until the flight departs.

7. In flight & at arrival

Cabin crew check on the child and assist with any approved connection. At arrival, staff escort the child to the named pick-up guardian, who must show matching photo ID and sign for the child.

Documents you’ll need (the UM form & more)

Unaccompanied Minor “Handling Advice” form

The core UM document. It records the child’s details and flight, the departure (sending) and arrival (pick-up) guardians and their ID, emergency contacts, and any medical, dietary, or special needs. You typically complete it at the airport on departure day.

Child’s travel documents

A valid passport for international travel, any required visa or Korea K-ETA, and — often recommended or required — a notarized parental/guardian consent letter from a non-traveling parent.

Guardian identification

Both guardians need government-issued photo ID. The pick-up guardian’s ID must exactly match the name provided at booking, or the child will not be released.

2026 entry note: Korea’s K-ETA requirements have changed periodically and exemptions vary by nationality — verify your child’s K-ETA/visa status before travel using official Korean government resources.

Pre-call checklist

• Child’s passport and date of birth
• Exact spelling of the child’s name (as on passport)
• Departure guardian: name, address, phone, ID, relationship
• Arrival/pick-up guardian: name, address, phone, ID, relationship
• Preferred dates and nonstop flight options
• Visa/K-ETA confirmation if applicable
• Payment method, and any medical/dietary needs or labeled medications

Good to know: connections, pick-up & contingencies

• If a connection is unavoidable, staff escort the child between flights — but overnight or tight/last-flight connections may be refused.
• If the named pick-up guardian doesn’t arrive, the child stays in airline custody until a verified guardian is confirmed; additional fees or a return flight may apply — always have a reachable backup contact.
• Avoid the last flight of the day so there’s recovery time if the flight is delayed.
• Pack a carry-on with snacks, entertainment, a charged phone and charger, a comfort item, and labeled medications.
• Brief your child that a uniformed Korean Air staff member will help them, and keep your phone on from drop-off until pick-up is confirmed.

Korean Air–Asiana merger: what it means for UM bookings in 2026

Korean Air and Asiana are integrating, with full integration targeted for December 17, 2026, after which Asiana operates under the Korean Air brand. For now, book UM service with the airline that operates the flight — if a segment is Asiana-operated, confirm whether Korean Air or Asiana UM rules apply. After integration, expect Korean Air UM policies and fees to govern combined operations, with more route options through ICN but possible schedule and aircraft changes during the transition.
