Block time and connection math
| Measure | Value |
|---|---|
| Airport pair | San Francisco (SFO) → Buenos Aires (EZE) |
| Great-circle distance | 10,410 km (6,468 mi) |
| Non-stop flight time | 12.91 h (12 h 55 min) — 850 km/h + 40 min taxi model |
| One-stop total (est.) | ≈ 15.4 h (15 h 24 min) |
| Two-stop total (est.) | ≈ 19.4 h (19 h 24 min) |
| Time-zone shift | 5 h ahead (UTC−8 → UTC−3) |
Estimates use the site-wide 850 km/h cruise + 40-minute taxi model; real block times drift with winds and routing.

Airlines planning the SFO → EZE leg start from the same arithmetic this page uses: 10,410 km ÷ 850 km/h, then the 40-minute airport allowance. Each stopover adds ground dwell at the hub, so the totals model out to about 15.4 hours for one stop and 19.4 for two.
The clock moves 5 h forward (UTC−8 → UTC−3), so a morning departure can land well into the local evening.

Montevideo (MVD) is the nearest alternative endpoint, 205 km from Buenos Aires — close enough that some fares from SFO price it as the same destination. From SFO, reaching MVD instead takes about 0.9 h — less airborne time than the 12.91 h non-stop, and the surface leg into Buenos Aires still has to be won back.
Where a matching calculator page exists (SFO → MVD among them) the links are in the Related list below. Remember the destination is the point: any airport below that adds more than a couple of hours of surface time to reach Buenos Aires needs a substantial fare gap to justify.
