About This Route
Buenos Aires (EZE) is a marquee South American destination, reachable in business class via LATAM and United on lie-flat widebodies. The overnight flights from US southern gateways make a flat bed especially valuable. Award demand peaks in the US summer and around the Argentine shoulder seasons.

💡 Insider Tip
The long overnight to EZE makes business class worth it. LATAM from its regional hubs and United nonstops (from Houston/Newark) both release award space. Search 2-5 months out. Like São Paulo, this is a lower-competition route in award content with genuine availability - a good under-the-radar sweet spot.
