Where you can fly nonstop from Boise this winter (2026–27)
Every nonstop from Boise Airport (BOI) this winter, including the new Honolulu and Santa Rosa seasonals, with indicative fares checked Oct 16, 2026 and labeled round trip or one way.
Prices checked October 16, 2026, between 10:46 and 10:50 AM MT
Winter is when a nonstop matters most. A missed connection in a snowstorm can eat a day of a short trip. Here's every nonstop Boise Airport (BOI) lists, sorted by what's running this winter. We also include a one-time price check so you know roughly what to expect.
How to read the prices on this page
- Every fare below is indicative and subject to change. We last checked it on October 16, 2026, between 10:46 and 10:50 AM MT, on Google Flights only. We didn't compare against airline websites or other booking sites. Another source may show a lower or higher price, so this is not a "cheapest fare" list.
- Prices are for 1 adult, economy, nonstop, for one sample trip: Tue Jan 12 → Tue Jan 19, 2027. Santa Rosa is the exception at Sat Jan 16 → Sat Jan 23, because that's when we found a nonstop. Each fare is labeled round trip (RT) or one way (OW).
- Google says its prices include standard taxes and fees. Checked bags are not included. Every fare we recorded showed 0 checked bags. Most showed 1 carry-on included, but United's fares to San Francisco, Denver and Chicago O'Hare showed no carry-on. Where an airline ties United's price, we show both. The lowest fares are often basic or saver fares with tighter change and seat rules, so read the fare rules before you buy.
- For a round-trip price, confirm the return flight is also nonstop and fits your schedule when you book. The airline or booking site confirms your final total.

Honolulu, in practice: the nonstop takes about 6 hr 47 min westbound on the flight we checked. HNL serves Oahu, so Maui, Kauai, and the Big Island need another flight. See our Boise to Honolulu guide.
Santa Rosa, in practice: the nonstop takes about 1 hr 50 min on the flight we checked. It lands at Charles M. Schulz–Sonoma County Airport, closer to wine country than SFO or OAK.

Winter booking tips from Boise
- Compare one ways too. On several routes the lowest round trip and the lowest one way were on different airlines. Two one-way tickets can sometimes beat a round trip. Since they're separate tickets, a delay on one doesn't protect the other.
- Price the bags. None of the fares above included a checked bag, and some United fares didn't include a carry-on. Add your bags before comparing. Google Flights has a bags filter that does this.
- Read the fare rules. The lowest fare is often the most restrictive on changes, refunds, and seat selection. In winter, flexibility can be worth a little more.
- Confirm seasonal dates. Winter-only routes like Palm Springs, Bozeman, and Chicago Midway don't fly every day of the season. Check the airline's schedule for your exact dates.
- Give yourself a buffer in a storm. Nonstops remove the connection risk, but they don't remove weather. Check your flight status with your airline before you drive to BOI.
