Terminal B hosts 2 airlines.
From the shared security rotunda, Concourse B breaks left
Concourse B peels off to the left from Spokane’s main post-security rotunda, forming its own compact wing that handles Delta and United departures. The airport signs at the rotunda list Concourse B along with Concourse A and Concourse C, so check the monitors there before you commit to the hallway. Walking time from the central checkpoint to the end of B is usually under 5 minutes at a normal pace.
Delta and United split most of the jet bridges along this concourse, with Alaska flights typically using the neighboring concourses instead. The gate area count is small enough that you can see most of the B concourse at a glance once you turn off the rotunda. Because GEG is on the smaller side, you often see mainline and regional jets parked door-to-door here during the morning and late-afternoon banks.
All food, drink, and retail for Concourse B currently sit outside the concourse itself, tied to the central terminal core that also feeds A and C. That means your last chance to grab a sandwich or coffee before a Delta or United flight usually happens in the main rotunda zone near security rather than down a dedicated B hallway. Plan on hitting a central terminal spot for snacks or water bottles before you walk the 3–5 minutes to your gate.
With no catalogued lounges inside Concourse B, flyers with Delta Sky Club or United Club memberships won’t find a branded space attached directly to their gates. Spokane International Airport’s official materials list concourses A, B, and C but do not list any club lounges by gate or concourse. If you want quieter seating, look for emptier rows of chairs toward the end of B, away from the rotunda side where boarding zones tend to crowd up.
Shopping works the same way: no individually listed shops line the short B hallway according to current airport maps, so any last-minute souvenirs or charging cables come from the shared retail in the central post-security area. Since all three concourses feed off the same rotunda, one quick lap there covers your options before you commit to the B corridor. Figure on an extra 10 minutes if you need to shop and then walk to a gate at the far end of B.
Boarding for Delta and United in Concourse B typically starts 30–40 minutes before departure, and lines can back up into the main walkway because the gate zones sit fairly close together. Power outlets are limited compared with bigger hubs, so charge in the central terminal if your connection is tight and your battery is low. One practical move: clear security, grab what you need in the rotunda within 15 minutes, then head straight to B and stay put until your group is called.
