United → Dulles (IAD)
SMF Terminal A · IAD is a United hub · about 5 hours
- ~1 a day 6–7 weekly
- Morning or late evening
- About 5 h 00 m eastbound
One departure most days, with published times spread between early morning and late evening depending on the season. Roll off it and there is nothing behind it that day on United nonstop.
The saving grace is that Dulles is a United hub. If the nonstop is hopeless, United can get you there through Denver, Chicago, Houston or Newark on a single carrier — and Denver in particular has enormous frequency out of Sacramento. On this route the connection is not a fallback, it is a legitimate plan A.
