Using LANPASS km to Upgrade
Just curious, how easy is it to use LANPASS km to upgrade an economy class ticket to business? Possible to do online, or must one call in?
I don’t see any mention on the website of the fare category making a difference (as is the case for coupon/Comodoro upgrades). I also see a note on LAN saying this is a benefit with "limited" availability, but I'm not sure how to interpret what that actually means!
Secondly, is it possible to use km to upgrade if the itinerary includes a TAM segment? I’m looking at a possible trip in October that would involve 1/4 segments that is operated by TAM, but my read of the site suggests that km upgrades can only be used on LAN operated flights.
