Greetings Iberia flyers! I have asked over at the LAN forum but so far with no luck so I thought I might try here.

I am trying to understand qualifying flights for credits to the LANPASS program. According to LAN.com tickets with fare bias codes beginning with "ID" or "AD" are not eligible for kilometer accumulation. My problem is that just doing a dummy booking only gives me the class "I" and nothing more. Can anyone shed some light on this? Perhaps "ID" and "AD" fare basis codes are well known to members of this forum?

The ticket in question would price at about US$4000 so it would be a deal breaker if the flight is ineligible for point (kilometer) accumulation.

Thanks in advance for any insights.
