That's why I would advise engaged flyers not to build strategies where their (re-)qualification depends on last-minute, potentially disrupted travel wherever possible. Travel in the dying days of December is always going to be risky, given what happens in both CDG and AMS if a snowflake shows up within 50 clicks (or, in AMS, if the wind gets above 5 knots!

)
But a "retro-claim" on a straightforward KLM flight can be initiated as soon as you land. Try it next time!
