Ten overnight hours from the US — the route where a lie-flat seat pays for itself in the first morning meeting.
Buenos Aires' international gateway is Ezeiza (EZE), about 22 miles from the city center. From North America it's a 9–11 hour overnight run: American flies from Miami, Dallas–Fort Worth and New York JFK, United from Houston and Newark, Delta from Atlanta, with Aerolíneas Argentinas and LATAM adding their own lie-flat services. From Europe, Iberia and Air Europa via Madrid, British Airways from London, Lufthansa from Frankfurt, and Turkish via Istanbul carry the traffic.
Because nearly every long-haul arrives overnight, business class is unusually rational here — you land at breakfast and work the same day. Seasons are inverted: the southern summer, December through February, is peak, and July brings a second bump for ski traffic to Patagonia.

| Route | Typical published fare | Notes |
|---|---|---|
| From the U.S. | $4,500–$9,000 round trip | Miami and Houston usually price lowest; December–February peaks hardest (as of August 2026). |
| From Madrid | €3,000–€6,500 round trip | Iberia vs Air Europa competition makes Madrid the value doorway from Europe. |
| From London | £3,800–£7,500 round trip | BA nonstop, or one stop via Madrid — the connection often saves four figures. |
For the December–February southern summer, book four to six months out — those cabins fill with holiday and Antarctica-cruise traffic. March to November is the value window, with April–May and September–November the sweet spots: pleasant weather, soft fares, and the widest consolidator discounts. Biirdee prices US, Madrid and one-stop routings against each other on every quote.

As of August 2026, published round trips from the US typically run $4,500–$9,000 and €3,000–€6,500 from Madrid. Biirdee's unpublished fares usually undercut those ranges by 30–60%.
Roughly 9 hours from Miami, 10–11 from Houston, Atlanta or New York, and 12–13 from Madrid or London — almost all of it overnight, which is exactly when a lie-flat seat matters most.
American's refreshed 777 cabins and United's Polaris are the strongest US options; from Europe, Iberia's next-generation business class on the A350 leads. LATAM is the pick for connecting onward within South America.
International long-haul lands at Ezeiza (EZE). Aeroparque (AEP), close to downtown, handles domestic and regional flights — useful if you're continuing to Patagonia, Mendoza or Iguazú.
