KLM Flight Booking
Hubs: Amsterdam Schiphol (AMS).
KLM Royal Dutch Airlines is the world's oldest airline still operating under its original name, hubbed at Amsterdam Schiphol. It is part of the Air France–KLM group and SkyTeam, with Delta as its US joint-venture partner.
KLM serves about a dozen US gateways nonstop to Amsterdam, and Schiphol's single-terminal design makes it one of the easiest European hubs for connections to the rest of Europe, Africa, and Asia.
KLM's appeal is Amsterdam Schiphol itself — a single-terminal hub that makes tight European, African, and Asian connections far less stressful than the sprawling alternatives. As Delta's European partner it slots neatly into US itineraries. Our agents book KLM and compare a Schiphol connection with the other European gateways on your route.
Our partner agency's licensed agents book KLM in every cabin and compare it with other carriers on your route. Call (708) 866-8751, 24/7, every day.
