Amsterdam to Denver (AMS–DEN) — Airlines, Schedules & Connections

Dutch passport holders travel to the US under the Visa Waiver Program (VWP) using ESTA. Apply at esta.cbp.dhs.gov at least 72 hours before departure. ESTA costs USD 21 (about EUR 20), is valid for 2 years or until your passport expires, and allows multiple entries of up to 90 days each. Your passport must be machine-readable and have an electronic chip (all modern Dutch passports qualify). If ESTA is denied, you need a B-1/B-2 visa from the US Embassy in Amsterdam.

Direct flights from Amsterdam to the US are plentiful. KLM and Delta (joint venture partners) serve New York JFK (7 hours 45 minutes), Atlanta (9 hours 30 minutes), Los Angeles (11 hours), Chicago (8 hours 45 minutes), Boston (7 hours 30 minutes), Minneapolis, Salt Lake City, Portland, and more. United flies to Houston, Newark, Washington Dulles, and San Francisco from Schiphol. Total, around 12 US cities have nonstop Amsterdam service.
