LAN responded today (4 weeks after my initial message) with the following:
Dear Mr. skywalkerLAX,
We inform you that we have received your request of category match.
Regarding this, we inform you that we have cheked the attached statement, but there is no flights in LAN routes, therefore we need to know the reason why you want this macth to be done.
Thanks for choosing LAN,
LANPASS Service
So I answered that our operations in South America are new and therefore I had no reason to fly these routes in 2008.
Oh well, lets wait for the answer. I expect it at the end of February.
Cheers,
S
