Hi, this is going to be my first flight with KLM, from Buenos Aires to Amsterdam.

My status in SkyTeam allows me to choose my seat in advance for free, but not for my travel companion. I haven't selected any seat yet. So my questions are:

1) Am I going to be able to select both seats for free during check-in or will they be randomly assigned?
2) If they will be randomly assigned during check in, should I choose mine for free before the check-in period, and then my travel companion will be assigned the seat next to me?

Thanks!
