Which airlines fly the route (and which are cheapest)

A single reference carrier plus strong hub alternatives define this market:

• Air Europa — the carrier that links Paraguay and Spain, operating the corridor and usually setting the benchmark fare.
• LATAM (via São Paulo or Santiago) — competitive one-stops across its dense Brazilian and Chilean networks.
• Aerolíneas Argentinas / LATAM (via Buenos Aires) — the natural routing for travelers in Paraguay’s southeast.
• LATAM (via Lima) — a Pacific-side alternative.

The key: Air Europa sets the corridor’s reference price, but one-stops via Buenos Aires, São Paulo, or Santiago can be meaningfully cheaper if you have time flexibility. Compare all Asunción–Madrid routings at once before you commit.

Airports: Silvio Pettirossi (ASU) and Madrid-Barajas (MAD)

Asunción – Silvio Pettirossi International (ASU)

Paraguay’s main international gateway, in Luque about 10 km from central Asunción — one of the closer capital-to-airport distances in South America.

• Arrive 3 hours before an international departure.
• Transit: taxi or rideshare (~20–30 min from downtown); allow time in Asunción traffic.
• Tip: Silvio Pettirossi is a smaller airport with limited long-haul frequencies, so build buffer time around connections.

Madrid – Adolfo Suárez Barajas (MAD)

Your gateway into Spain and onward Europe. Air Europa and SkyTeam partners typically use T1; Iberia/oneworld use T4/T4S. Confirm your terminal on aena.es before arranging ground transport. Metro line 8, the Exprés Aeropuerto bus (24 h), and the Cercanías C1 train all reach central Madrid in 30–40 minutes.

When is the cheapest time to fly to Madrid?

Public search engines show consistent seasonality on Southern Cone–Spain corridors:

• May, September, October, and November — the cheapest months: demand drops after the European summer and outside Paraguay’s holiday peaks.
• February and March — another low-price window.
• December–January and July–August — the most expensive, driven by holidays, the diaspora return, and the European summer peak.
