I'm flying ex AMS to the US in a few days on KLM. The flight is showing no availlability in any class of service on Galileo. I'm familiar with the procedure in the US, but not AMS. My questions:

What is the typical Euro range for the compensation?

Where does one volunteer - check-in desk, gate, telephone check-in the day before?

Any strategies for being selected for bumping? I am Worlperks Platinum if it makes a difference.

Thanks for your help.
