Only correct for intra-European flights. There seat selection happens at check-in time, 30hrs before departure.
On transatlantic (and I assume other flights leaving Europe as well) offer seat selection from 90days before departure. A colleague just used that feature a few days before for a flight between AMS and SFO.
