About KLM Royal Dutch Airlines
KLM Royal Dutch Airlines is the flag carrier of the Netherlands. The Dutch home market is small, so KLM works mainly as a connecting airline: passengers from across Europe transfer at Amsterdam Schiphol to long-haul flights bound for the Americas, Africa, the Middle East and Asia. Regional European routes are flown by its subsidiary KLM Cityhopper. KLM belongs to the Air France-KLM group and to the SkyTeam alliance. Intercontinental flights are sold in World Business Class, Premium Comfort and Economy.
You can find KLM on IATA.co by searching live fares in the booking portal or by calling the flights API. KLM fares appear in your search results whenever our flight suppliers offer them for your route and dates. Bookings are paid from the prepaid balance on your account. Check the fare rules on screen before confirming, as baggage and change conditions are not the same for every fare.
