Buenos Aires EZE - Asuncion ASU, eff 15NOV22, 3x w, operated by JetSMART Argentina. This will be the 3rd international route for the Argentine franchise, and the 12th for the group.
Fares start at around US$60 o/w for the 1h 30 min flight. Not much of a low cost fare it would seem, but then full service Aerolineas Argentinas is charging $150 for the same route, but out of AEP.
