Decision matrix for BOI
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.
When the clock matters
BOI uses America/Boise (MST, UTC-07:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
