About Boise Airport
Boise Airport is a mid-size regional hub serving the Treasure Valley with direct flights to major West Coast hubs and limited cross-country options. Delta and Southwest dominate the schedule, with Delta operating the most frequent service to Salt Lake City, Denver, and Seattle. It's a straightforward, uncrowded airport — you'll rarely wait more than 10 minutes at security — but international options are limited. Most Americans flying internationally from Boise connect through Salt Lake City (SLC), Denver (DEN), or Seattle (SEA), which actually often works in your favor for pricing since you're combining a cheap regional flight with a connecting route. The airport sits just 4 miles south of downtown Boise, making ground access quick and cheap compared to larger metros.
Terminals & Airlines
Boise Airport operates a single terminal building with one main ticketing level and one security checkpoint. Southwest and Delta occupy the bulk of gates (B1-B20), while United, Alaska, and American share the remaining gates (A1-A15). Allegiant operates from a separate cargo-adjacent gate. There's no terminal confusion here — it's refreshingly simple. All major airlines check bags, ticketing, and TSA PreCheck enrollment in the same central area.
Getting to the Airport
Uber/Lyft from downtown Boise costs $12–18 (4 miles, 10–15 min). Valley Transit bus Route 40 ($2.50, 30–35 min) runs from downtown to the airport terminal hourly 5am–11pm. Rental car shuttles from major companies depart near baggage claim every 5–10 min. Parking in the economy lot runs $15/day; valet is $22/day. If you're flying out early, Uber is worth it to avoid the lot shuttle wait.
Parking
The main economy lot (Lot A) is $15/day and fills up before 9am on peak travel days. Use the online reservation system on the airport website for guaranteed spots at $13/day. Park & Fly services like Park Boise charge $10/day but add 10 minutes to ground transport. Valet ($22/day) is surprisingly reasonable and worth it if you're gone more than 3 days and flying early. Skip on-airport parking for trips longer than 5 days — use a Park & Fly lot instead.

Pro Tips for Flying from Boise
Boise has zero TSA PreCheck lines most mornings — if you don't have it yet, enroll here and sail through in 5 minutes. The enrollment office is in the main terminal near baggage claim.
If you're priced out of direct BOI flights to the coasts, book BOI→SLC on Delta or Southwest ($89–140) and connect to international hubs. Salt Lake City is 60 minutes away and has 3x the European, Asian, and Latin American options. Total savings often exceed $200 vs. driving.
Southwest operates most BOI departures but doesn't allow international bookings beyond Mexico. If you need flexibility for international trips, stick to Delta or United for direct-through-connection options.
The airport wifi is terrible — pay $7.95 for 24 hours through TMobile if you need reliable connectivity while waiting. Better yet, download your boarding pass before arriving.
