Other North & South America Frequent Flyer Programs - LAN Airpass on LH-Ticket -worth cheating?

Sorry double-post (M&M Forum)...

Hi folks,

i´m going on a round trip to chile this autumn, flying in to SCL on a LH-award ticket in F (MUC-GRU-SCL (opt. by TAM)) . I´m now up to a buy some domestic segments on LAN trying to get the Airpass which is obviously limited to oneworld tickets.
The question now is how this is checked, because booking is not a problem at all without any proof? Showing the intl. Boarding pass at the check in or even at the gate? How frequently is this checked? What about checking in online and just walking through? How much would be the "fine"?
Any experiences yet?

PS: The the price for a regular tickets is more than double, so i´d take some risks!

Thanks for your help!

Normally they such passes must be booked with a reference to the original long-haul ticket number so I'm not sure how you'd book one without that. If you can then have at it, I'd say.

i have booked a LAN south american airpass twice already - nobody wanted to see the longhaul boarding pass - however i had the longhaul on LA.
what you could do is to make a reservation only for FRA-SCL-FRA on the LAN website and use the booking reference number for the reservation of the SAA airpass.

BTW, maybe of interest to all others:

2. ELIGIBILITY
Level Arriving with LAN (SA3) applies for passengers NOT residing
in South America holding an international ticket showing arrivals
to and departures from South America on any aircraft operated
by LA/LP/LU/4M or XL.
From Europe, it also applies to flights operated by IB.
Also applies for brazilian residents holding an international
LU/LA/LP/4M or XL ticket showing departures from and arrivals
to Brazil.
Level Arriving with Others (SA4) applies for passengers NOT residing
in South America holding an international ticket showing
arrivals to and departures from South America on airlines participating
on the oneworld alliance (must have MITA agreement
with all the carriers participating in the routing). Also applies for
South African Airways (SA), Aeromexico (AM), Air China (CA) and
United Airlines (UA). Passengers of our frequent flyer program LANPASS qualify for the
South America Airpass. Compensation passengers also qualify.
Passengers with ID/AD tickets do not qualify for the South
America Airpass.

what would be interesting is how they try to figure out whether you are a brazilian resident or not.

Can anybody say if the above text about Brazilian residents applies to Brazilian residents, arriving from outside South America and have a ticket to Brazil with Lan, or living in Brazil and flying to another city in SA with LAN?
