I checked out out all 8 OW FF plans circa 2001, info was quite hard to get on half the plans (including IB and LA), but at that time both IB and LA plans were awful compared to the rest of OW (maybe EI was equally bad). I think LA and IB have improved substantially since then, but I would guess they are about half the AAdvantage value. But both IB and LA share a characteristic: they offer some high value benefits for their Emeralds in their home city (MAD and SCL). Things like free valet parking, free car washes while at the airport, free limo service -- quite valuable, but only if you live in MAD or SCL, and qualify for top-tier.
