Route 42A hits both SMF terminals every 30–60 minutes
Yolobus Route 42A runs between Sacramento International Airport (SMF) and Davis/Woodland daily, stopping at Terminal A and Terminal B. The bus usually comes every 30 minutes on weekdays during the day and about every 60 minutes late evenings and on Sundays, so check the latest timetable before you bet a flight on it.
As of early 2026, a single adult fare on Route 42A sits in the low single digits in dollars, paid with cash on board or via Yolobus mobile options. Drivers accept exact cash only, and there’s no change given, so have small bills ready if you’re boarding at SMF. Keep your paper transfer or receipt until you’re off the bus if you need to connect to another Yolobus route in Woodland or Davis.
At the airport, Route 42A picks up curbside outside both Terminal A and Terminal B; follow ground transportation signs to the “Public Transit / Yolobus” stop. The stop is in the same general curb zone as hotel and off-airport shuttles, so look for the Yolobus sign and the route number 42A printed on the bus before you get on. The bus stops in one direction only, so confirm the sign shows your destination (Davis, Woodland, or Sacramento-bound) before you tap or pay.
Service typically starts in the early morning hours and runs until late evening, covering most first and last bank of flights at SMF. Midday service toward Davis and Woodland lines up reasonably well with common departure times, but overnight there is usually a gap of several hours with no Route 42A buses at all. If your flight lands after the last run, you’re looking at a rideshare or taxi instead.
Under-seat space and overhead racks on Route 42A can handle a standard 22-inch carry-on plus a personal item, and drivers see airport bags all day. If you’re hauling multiple checked bags or oversized gear, plan to keep them out of the aisle per Yolobus rules. The stop spacing between SMF and downtown Woodland or Davis means you’ll see several red lights, so figure roughly 25–40 minutes to Davis and slightly less to Woodland, depending on traffic on I‑5 and CA‑113.
Practical tip: when you land at SMF, pull up the live Yolobus tracker before you leave the gate and only walk out to the curb once you see the next 42A within 10–15 minutes of arrival.
