A quick internet search reveals claims of having had to use final reserve fuel.

could you please share some links showing KLM aircraft having had to use final reserve fuel?
I found one incident of a Fokker 70 of KLM Cityhopper which landed in Bremen in 2004 with 750 kg of remaining fuel.

Otherwise there have been very few unplanned landings in recent years because of unexpected headwind, lower than desired flightlevels etc. I think it is around 1 unexpected landing every 2 years thans to KLM using CONT90 or CONT99.
