Amsterdam is in my top 3 favorite places. The canals, the laid back vibe, the abundance of ultra famous art, the endless supply of cheese! These flights are January through late March and again in late October through December 1st, including the week of Thanksgiving.
These are for 6, 7, 8, and 9 day trips and are with United so they have all the amenities. Most flight schedules only have one layover that is under 3 hours. That means you can get to Amsterdam in 11 hours! Whaaat! If you plan a longer trip, you can venture into the country side to see some windmills!
