Aerolineas Argentinas A313 (via FTE on the outbound, direct on return)
Aerolineas Argentinas/Austral B732/M83/M88 (3 choices: via Trelew, via RGL, or direct)
American Falcon/LAER F28 (via CRD, FTE)
American Falcon is operating on an erratic schedule at present, so double check when they are operating their services.
Aerolineas Argentinas/Austral maintains high frequency to both IGR and USH year round, with a minimum of 5 flights a day.
Aerolineas Argentinas/Austral service has improved dramatically, and the airline is modernising. 2 of their 5 oldest 732s will be retired by the end of the month, and nearly all the rest of the fleet is of '80s-build.

I know that there are some Argentines that could help you with this maybe a little more than I could but here is what I know.
Airlines in Argentina include
Aerovip(No help on that route)
LAPA/Southern Winds/Federales(Too diificult to explain)
From Iguazu you can probably fly Aerolineas Argentinas to AEP(Jorge Newberry), which is just north of downtown Buenos Aires, and then either fly from AEP to USH or take a bus to Ezeiza(EZE), where you could fly to USH. All flights could be done on Aerolineas Argentinas. If you fly from EZE to USH you would probably fly the Airbus 310.
Hope that helps a little. I know that there are many excellent Argentine sources on this board who will be able to help you further. Check out the website for Aerolineas Argentinas before you do anything else.
