Essential Refund Guide: Japanese & Korean LCCs

​May 21, 2025


Have you ever asked yourself, "Why is the refund fee more expensive than the flight ticket?" or "Why did the airline suddenly claim it's non-refundable?"

Don’t worry—this detailed guide will walk you through the refund rules of Japanese and South Korean low-cost carriers (LCCs), equipped with practical, expert insights!

Key Highlights: Different "Personalities" of Japanese vs. Korean LCCs

  • South Korean LCCs

South Korean LCCs are fiercely competitive, accounting for 65% of domestic and 30% of international routes. Their refund policies tend to be more "flexible." Refunds are possible both before and after departure (with service fees deducted), and the bar for involuntary refunds is comparatively low

  • Japanese LCCs

In contrast, Japanese LCCs are more "cautious." Only 35% of domestic and 15% of international flights are LCCs. Their refund policies are "strict"—voluntary refunds after departure are usually not allowed, and involuntary refunds may require delays exceeding four hours. They're strictly "rule-following."


Agent Toolkit: 9 Common Refund Pitfalls & How to Avoid Them

1. Refund Early—It Pays Off

For most airlines, even those permitting post-departure refunds, pre-departure refund success rates and processing speed are significantly higher.

Atlas Tip: Don't wait until the last minute, even if post-departure refunds are allowed.

2. Group Bookings—Split Before You Refund

  • Scenario: A customer books for 3 people and wants to refund 1 ticket.

  • Pitfall: Refunding the whole PNR may result in canceling all tickets.

  • Solution: Always split the PNR and refund only the intended passenger.

3. Refund Deadlines—Miss It, Lose It

Reminder: Each LCC has different refund timeframes. Missing them can result in losing the refund.

Japan:

  • Within 10 days post-departure:

    • 7G, 6J, JH, MZ, MM: Voluntary refunds not allowed; only involuntary.

    • BC: Post-departure voluntary refunds cover only taxes; full involuntary refunds only if done before departure.

  • Within 30 days post-departure:

    • HD: Voluntary refunds post-departure cover only taxes; involuntary allowed.

South Korea:

  • Within 1 year after issuance: 7C, BX

  • Within 30 days post-departure: RS, ZE

  • Within 60 days post-departure: LJ

4. Involuntary Refunds—Know the Valid Scenarios

Some airline self-service portals don't support involuntary refunds. Confirm before processing.

Japan:

  • Before departure:

5. Voluntary Refunds—Watch for These Details

Even if the airline supports voluntary changes, rules differ.

7. Medical Refunds—Required Documents

Customer: “Can I get a refund if I’m sick?”

Answer: Depends on the airline.

For those that allow it, you’ll need:

  • A passport copy

  • An English-language medical certificate

8. VCC Refunds—Avoid Getting "Stuck"

Warning – JH & MZ:

  • Refunds deduct fees first, then return the balance.

  • VCC users must ensure:

    • Card isn’t expired

    • Balance ≥ refund fee (typically ≤ ¥8000)

    • Card supports multiple authorizations

Warning – HD, 7G, 6J:

  • Require original payment card number and validation.

  • VCC users risk rejection if card is expired.

9. Post-Flight Refunds—Language Barriers

Warning – BX & RS:

  • PNRs are not accessible online after departure.

  • Refunds require calling Korean-speaking customer support.

Solution: Advise customers to confirm bookings before departure.

  • Atlas currently does not handle post-flight refunds for BX and RS.
