This just in: KLM Royal Dutch Airlines is lowering fares from the U.S. to four ever-popular cities in Europe by up to 35 percent, in Cyber Monday sale launching December 1.

This winter and spring, the sale gives you the chance to explore art in Amsterdam, mosques in Istanbul, thermal baths in Budapest, and street food in Bucharest.

The sale covers any U.S. gateway city, including NYC, Washington, D.C., Atlanta, Chicago, L.A., and San Francisco -- for travel between December 29, 2014 and March 27, 2015. While exact numbers are pretty hush-hush, we did reach out to KLM to find that rates from JFK, as one example, will be as low as $655 round-trip. 

If the prices don't sway you, our friends at the airline remind us of a few fantastic events happening during the sale months, including the Budapest Fish Festival (February 13-16), the 5 Days Off Electronic Music & Art Festival in Amsterdam (March 4-8), and Istanbul’s Mercedes-Benz Fashion Week (March 16-21).
