Currently considering a trip to Argentina. ANA tools shows limited availability on LH Business but quite a lot on First (both directions). Apart from the FCT at FRA, is First actually worth it over Business? (This would be an award booking.)

Also I'm not sure if Swiss also fly to EZE and whether that's a routing that the ICC will offer. Would that be better?

We won't usually fly First and if I could get Business on Swiss then maybe that would be OK?

Yours, confused.
