I booked my ticket home today, Buenos Aires to Amsterdam. I'm flying together with my friend who had booked BA -> Amsterdam -> Düsseldorf, but is getting off in Amsterdam as it is as close to home. Booking to Düsseldorf has been cheaper than booking only to Amsterdam.
I actually bought a return ticket. Without a return ticket the same flight would have cost almost 1000 dollar more.
So now there are two seats one from Düsseldorf to Amsterdam and one from Amsterdam to BA, which are now going to be empty.
