Route 4 hits Boise Airport every 30 minutes on weekdays
ValleyRide Route 4 is the only fixed-route bus serving Boise Air Terminal/Gowen Field (BOI), stopping at the Main terminal and running between the airport and downtown Boise. This standard city bus is part of the Valley Regional Transit system, so you pay normal local fares, not a special airport surcharge. Look for the Route 4 sign at the airport stop near the Main terminal arrivals area.
A regular adult one-way fare on ValleyRide Route 4 typically matches standard Boise city bus pricing, so you’re paying local rates instead of a premium shuttle fee. You buy your ticket onboard from the driver using exact change or with an accepted pass; there’s no separate airport ticket booth. Compared to taxis and rideshares that can run many dollars more into downtown, this keeps your airport transfer budget-friendly.
On weekdays, Route 4 usually runs about every 30 minutes during daytime hours, with reduced frequency in the early morning and later evening. Service patterns can shift on weekends and holidays, so check the latest ValleyRide schedule before you land or leave. If your flight arrives close to the end of service, build a buffer of at least one full headway so you’re not watching the last bus pull away.
ValleyRide Route 4 connects the Main terminal at BOI with central Boise stops that link to other local routes, letting you reach key areas of the city without a car. If you’re transferring to another ValleyRide route downtown, plan at least 15–20 minutes between scheduled arrival of Route 4 and your next bus. That gap covers minor delays and keeps you from sweating a missed connection at the downtown transit center.
Practical tip: Check the exact Route 4 timetable for your flight’s day of week, then screenshot it while you still have Wi‑Fi at the Main terminal so you’re not scrambling for data at the curb.
