Discounted KLM rewards to Europe

I fly to Amsterdam often, despite trying to avoid Schiphol airport because it gets so congested and is frightening to stand in confined areas in long lines. The queues are always long at customs and the ceilings low..

KLM and Air France have really good discounted Promo Rewards starting at 3,600 miles from Paris to Rennes. But the big deals are on long-haul flights, like from Seattle. Get a discount of 50% on flights between Seattle and anywhere in Europe.NYC to Europe is also on sale.
KLM Royal Dutch Airlines, (Koninklijke Luchtvaart Maatschappij), is a genuine Royal Airline! The King of Holland has been seen flying their 747s.
