Terminal B regulars always mention one thing: there’s Dunkin’.
This Dunkin' Donuts sits airside in Terminal B at John Wayne Airport, after security and within a 5–7 minute walk of most B gates. It’s a straightforward coffee-and-doughnut stop, useful if you just need caffeine and a snack before a Southwest or Alaska flight. Expect standard airport pricing: drip coffee and basic doughnuts usually land in the $3–$5 range, with espresso drinks a couple dollars higher.
Hours vary a bit with flight schedules, but recent reports put opening around the early-morning bank of departures, typically before the 6:30–7:00 a.m. wave in Terminal B. Closing often tracks the last evening flights, so don’t count on it past the 9:00–10:00 p.m. window. Since there’s no strong chatter about sell-outs here, odds are decent you’ll still see doughnut options into the late morning.
The menu follows the standard Dunkin’ setup: hot and iced coffee, espresso drinks, doughnuts, bagels, muffins, and basic breakfast sandwiches. If you just want something fast before a 90-minute hop up to OAK or down to SJC, a medium iced coffee and a bagel sandwich will usually run under $12. If you’re trying to keep it lighter, stick to drip coffee or cold brew and skip the flavor swirls, which can push sugar and calories up quickly.
Lines in Terminal B cluster around the 6:00–8:00 a.m. departures and again around mid‑day boarding waves at gates B1–B10, so give yourself 10–15 extra minutes if your boarding time hits those windows. Mobile ordering doesn’t get much public feedback here, which usually means it functions but isn’t heavily used. Final tip: if security in B looks ugly, clear in A or C when TSA allows it, walk airside to Terminal B in under 8 minutes, grab Dunkin', then head to your gate.
