Houston to Buenos Aires in business.
Houston to Buenos Aires is United Airlines' sole nonstop link between the American Gulf Coast and Argentina, operating seven times weekly on a Boeing 777 configured with United Polaris business class in a 1-2-1 layout. The route is a natural fit for Houston's energy-sector corporate travel corridor, connecting the city's oil and gas industry directly with South America's Southern Cone business hubs, while also serving strong leisure demand during the Southern Hemisphere's peak season. Scheduled flight time runs approximately 9 hours 40 minutes to 9 hours 50 minutes southbound. Polaris business class offers a genuine lie-flat seat with direct aisle access, upgraded dining service, and an amenity kit for the overnight-style routing. As the only nonstop option on this corridor, United effectively controls premium-cabin pricing and scheduling, though seven weekly frequencies keep availability comfortable for most booking windows.

Two things worth knowing.
What our specialists check before they price IAH to EZE.
The Argentine summer (December-February) is peak season, particularly around the holidays — book several months ahead for the best fares and availability. March-May and August-October offer noticeably better value while avoiding both the coldest Argentine winter months and the busiest US holiday travel dates. Argentina's currency and economic volatility can occasionally create unusual short-term fare swings worth monitoring.

- The airports
- Houston's George Bush Intercontinental Terminal E is United's international hub, with the Polaris Lounge offering elevated dining and a dedicated pre-flight spa treatment area for premium cabin passengers on this near-10-hour route. Ministro Pistarini International's (Ezeiza) international terminal serves United through Star Alliance partner lounges. Allow extra time for immigration on arrival, as queues can be lengthy during the Southern summer peak.
