This is all very interesting to read, especially the rather consistent views herein concerning the difference between LAN in the air and LAN on the ground.

Here's a current concern that may fit into this discussion. I just flew BA from IAD to LIS, and then again from BCN to IAD--both via LHR. I was excited that this time around I could apply kms on these flights to my LANPASS account, which is at about 30,000 kms thanks to a flight last year between MIA and EZE. However, thus far LAN has only added a measly 1,871 kms to my account so far for that entire itinerary.

Is it a fight with LAN to get them to update kms? Would the BA flights somehow not be eligible for full km earning on LAN?

Thanks for anyone's input.
