Hi,
I know it is not that intresting but as of tomorrow seems like CO changed the equipment on the route to brussels from a 767 to a 777.
Not really a clue on why they did that, to my knowledge they do not need the extra capacity but that is maybe misinformation from me.
As a result a lot of extra seats are available (look e.g. at tomorrow

, and for people with already a confirmed exit seat check your reservation as my seat was not an exit seat anymore when they swapped the equipment (was done over the weekend as far as I can tell)
Regards,
