In 2026, whether KLM allows 2 bags depends strictly on your "Ticket Type" and "Loyalty Status." For Economy Light tickets, there is zero checked bag allowance. For Economy Standard/Flex, you are allowed 1 checked bag (23kg). To get 2 checked bags, you must either book a Business Class ticket (where you get 2 bags at 32kg each) or be a Flying Blue "Silver, Gold, or Platinum" member (or SkyTeam Elite). For a peer-to-peer "win" on 2026 "intercontinental" flights: Business Class passengers are also allowed 2 hand-luggage bags plus a personal item, with a combined high-value weight of 18kg. If you are an Economy passenger needing a second bag, it is a peer-recommended "high-value" strategy to buy the extra bag online at least 24 hours before your flight, which is often 30% cheaper than the "High-Intensity" fees charged at the airport check-in counter.
