Yes — January is often one of the cheapest months to fly from Boise Airport (BOI) because demand drops after the winter holidays. Look for off-peak deals and last-chance winter sales; however, be mindful of ski-season demand to mountain destinations like Sun Valley. Use fare calendars and set alerts to lock in low economy prices in January.
Baggage allowances for economy tickets from Boise Airport (BOI) depend on the airline and fare class; basic economy often restricts seat selection and charges for checked bags, while standard economy frequently includes one small carry-on.

Rental cars, private shuttles, and regional buses link BOI to these mountain and outdoor destinations; travel time by road ranges from about 2 hours to Sun Valley to around 3–3.5 hours to Idaho Falls depending on conditions. When booking economy flights, compare total route time including ground transfers to choose the most cost-efficient itinerary.
Arriving at Boise (BOI) FAQs
Cheap economy arrivals labeled as Economy Class (ECONOMY) typically include a standard seat, limited or no seat selection, and potential baggage fees depending on the carrier. Amenities vary by airline — some low-cost carriers charge extra for carry-on and checked bags — so add these fees to the total fare when comparing. For best value, compare full-price economy versus basic economy on the route and consider loyalty or credit-card perks that include baggage.
Upgrading from the cheapest economy fare often requires paying a fee or using frequent flyer miles; many airlines allow paid upgrades at check-in or in the booking manage section. Bid-for-upgrade programs and last-minute offers at the gate are common on some carriers, but availability is limited. If upgrades are important, consider purchasing a refundable or standard economy fare that offers more flexible upgrade options.
Yes — arriving on weekdays, particularly Tuesdays and Wednesdays, often yields cheaper economy fares compared with weekend arrivals. Early-morning and late-night arrivals (red-eye flights) can also be less expensive due to lower demand. Use a fare calendar to compare arrival dates and save on Economy Class (ECONOMY) tickets.
Yes — December holiday travel puts upward pressure on economy arrival fares, especially in the two weeks before Christmas and the days after New Year’s. If you must travel in December, book as early as possible and consider arriving several days before peak holiday dates to reduce costs. Alternatively, targeted mid-December or early January travel can be more economical for Economy Class (ECONOMY).
Cheap economy arrivals often bring travelers to major nearby cities such as Los Angeles, New York City, Chicago, Seattle, Portland and Salt Lake City — and from those hubs you can connect to smaller regional destinations like Sun Valley, Idaho Falls, Twin Falls or McCall. Consider multi-city itineraries or budget regional carriers for last-leg connections to smaller towns. Factor ground transfer times and local transport availability when planning low-cost arrivals.
