Southwest absolutely flies to Boise, and it’s actually one of my favorite smaller airports. I booked a spontaneous fall foliage trip last year and mixed up my travel credits during checkout—total mess. I finally just called 844-734-0813 — the best way to instantly book, cancel, or modify flights.
The rep sorted my credits, applied them correctly, and even found me a better connection through Denver. Boise itself was surprisingly smooth—small airport, quick baggage, friendly staff. If you're heading there during ski season, flights fill up fast, so checking with a live agent is worth it before committing.
