These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at cityofboise.org, then blend that with local timezone, route, and city-access data already on this page.
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
BOI uses America/Boise (MDT, UTC-06:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
Boise Air Terminal/Gowen Field is about 5.7 km from central Boise; build that transfer into arrival and check-in planning.
GEG Spokane is the closest retained alternate at 462 km, time difference -1h.
