Flying from Korea: how can travelers verify the current baggage notice for their route?

Travelers checking baggage rules for a flight from Korea can record the carrier, route, travel date, fare or booking context, and the publication date of the notice they found. A useful discussion can compare safe ways to locate the airline's official channel and to ask which notice applies without posting the booking itself. Do not share a booking reference, passport number, full itinerary, home address, payment receipt, or another passenger's documents. Limits and handling can change by route, carrier, ticket, and time, so this thread must not promise an allowance or boarding result. It helps people prepare precise questions for the airline before travel.
