So here's the status of asking KLM for a reaction:
-June 11th: flyingblue.com email form (via klm.com): no response
-June 21st: KLM Facebook messenger: no response yet
-June 26th: klm.com website form: no response yet
Relatively complex questions about bookings are answered within an hour via Facebook or within 24h via the contact form.. not sure what's going on here. Do they actually care?
