I've known that site for a while, but never knew that they had such detailed info! Thanks for the heads up - and THERE goes my afternoon, haha!
And while you are studying up, can you or anyone else figure out what the quoted language in red below means:
Prior to commencement of travel:
When a customer is unable to travel due to their own illness or the illness of a travel companion (family member or not), Air France and KLM will waive advance reservation/ticketing requirements and service charges (if applicable) when the customer wishes to travel later.
KLM will apply the same for an immediate family member who is not traveling
Not clear to me what benefit this is attempting to give to family members who are
not travelling.
