I just realized something, and confirmed it with KLM just to be sure.

Previously all European promo's were Europe 1/2/3. Now they are just 'Europe'. This means flexible pricing: The advertised price is ONLY when departing from Europe 1.

When departing from Europe 2 or 3 the price will go up by about 50%. While last year, the price was the same for all of Europe. Yet another devaluation (besides the ridiculous 20% discount...where are the 50% promo's like we used to have?).
