Verified travelerFlew with Alaska Airlines-Sep 2026
You may get bussed from plane to terminal & vis-a-versa. Just a heads up.
AllisonFlew with Alaska Airlines-Mar 2026
Boise airport is quick to get through security and very easy to navigate, so you don’t need to give yourself as much time as you normally would at larger airports.
Verified travelerFlew with Alaska Airlines-Jan 2026
Since I flew First Class I really have no advice! Everything was perfect! The ticketing agents were fantastic, flew through TSA Precheck, great announcements at the gate, quick boarding. My only suggestion is to check First Class prices before committing to the very expensive baggage fees and choosing a seat fee!!!
Verified travelerFlew with Alaska Airlines-Feb 2026
Dont wear all your clothes its not worth the discomfort to save on a checked bag.
Verified travelerFlew with Hawaiian Airlines-Jun 2025
Idaho Falls is not a large airport, so it was easy to find my way around. Take a meal if you want more than a snack.
LisaFlew with Alaska Airlines-Jul 2024
If they ask you to check your bag at the gate because the flight is full, you get to board sooner even if you don't check ALL of your bags.
