I'm guessing they actually do check to see that you're a resident since the prices are that much cheaper for locals.
I'm not sure this is the case. Just last week I flew on a locally purchased inexpensive LAN domestic ticket in Peru, and though I was asked for ID a check-in (my passport), at no time was it ever mentioned that the fare did not apply for me. It may be different in Argentina.
I think it is different for Argentina. The LAN website itself states specifically that you must be a resident to get these prices and then says something about article 4 of the resolution 35 in 2002 from the Secretary of Transportation. My guess is this means the Argentine government is partially subsidizing flights for residents in order to keep prices so low.
If someone has recent experience to the contrary then please let me know!
I think we're going to try and do Iguazu regardless, the lowest fares I've found are $274 each, which isn't horrible.
