Thursday Feb 11: no luck! The weebsite was barely working; I tried to OLCI a dozen or so times before finally succeeding at 5 hours before departure. On one of my unsuccessful OLCI attempts I saw that only one Biz class seat was left; by the time I was successful with OLCI I was not offered the chance to buy an upgrade. Flight had no more than 6 empty seats.

Today: success! Only 1 Biz class left empty; 9 were free at T - 5 hours.
