Harvey Milk Terminal 1

Security to B27 can feel like a 15-minute hike

Harvey Milk Terminal 1 handles Alaska, Delta, Southwest, Frontier, and some American flights, with 37 gates spread along one long, curved concourse. Check-in and security sit in the middle of T1, but the far B20–B27 gates can feel like a trek, especially with a roller bag. Build the buffer: add 10–15 minutes to whatever walk time you’d plan for Terminal 2 or 3.

Morning security: 6–8 a.m. is the pinch point

Security in Terminal 1 backs up hardest around Alaska’s first departures, roughly 6–8 a.m., when Google reviewers call the checkpoint a “zoo.” TSA PreCheck sits on the far-left side of the checkpoint and frequent flyers say that lane often moves faster than the central general lines, especially before 7 a.m. If you land from BART or AirTrain at 6:30 a.m., don’t assume you’ll be at B20 in 15 minutes.

Layout: low B-gates quiet, mid-B packed

Gates B1–B9 sit closer to the checkpoint and multiple reviewers note this area stays calmer than the Alaska-heavy mid-B cluster around B15–B27. If your flight leaves from B22 or B24, you can often sit near B3–B5 and walk down 7–10 minutes before boarding. Regulars say the crowd around B20–B27 gets dense when three or four Alaska flights load at once.

Power, seating, and those empty outlets by B3–B5

Along the windows near B3–B5, one local guide points out rows of unused outlets where you can usually find both a seat and a plug, even when the main mid-B seating is full. The boarding zones around B20–B27 draw complaints for not having enough seats when multiple 737s board together. If you care more about charging than staring at your exact gate, park yourself on the low-B side.

Lounges: Alaska, Admirals Club, and a Sky Club link

The Alaska Lounge in Terminal 1 serves the big share of Alaska passengers based here, with typical lounge basics and direct access to the B-gate side. American’s Admirals Club sits near B13 and handles the airline’s smaller SFO schedule from this terminal. Delta’s main Sky Club for SFO is at C3 in Terminal 2, about a 5–10 minute airside walk from the lower B-gates if you cut through the corridor instead of using AirTrain.

Food: Amy’s Drive Thru, Lark Creek Grill, Burger Joint

Amy’s Drive Thru in T1 runs vegetarian and vegan fast-casual staples at airport prices, with burgers and burritos often around the mid-teens. Lark Creek Grill offers sit-down plates and a bar closer to the central part of the concourse, handy if you’re near the mid-B gates and want a real meal. Burger Joint covers the quick burger-and-fries slot for under $20, while Boudin Bakery and Peet’s Coffee handle the bread-bowl-and-latte crowd earlier in the day.

Shops: basic newsstand coverage only

Hudson News and Relay cover the standard magazines, headphones, and last-minute charger needs, mainly around the central concourse near the main security exit. Prices track typical SFO markups, so expect to pay several dollars more for snacks than in the city. If you want anything more specialized than books, snacks, or toiletries, you’ll be happier walking over to Terminal 2’s shops.

Terminal connections and tight-transfer rules

Terminal 1 connects airside to Terminal 2, and SFO regulars say the walk between low B-gates and the C-gates runs about 5–10 minutes at a normal pace. Frequent flyers on Reddit stress skipping checked bags on tight connections that involve a far B-gate and another terminal, warning that delays at the jet bridge plus the walk can chew up 20 minutes easily. Many Alaska regulars with long layovers walk over to T2 for more food options, then return to their B-gate about 25 minutes before departure.

What regulars actually do here

Local flyers mention arriving earlier for Terminal 1 than for T2 or T3, padding their normal SFO routine by 15–20 minutes for morning departures. Alaska and American regulars often clear security, walk straight to their gate to confirm it on the screen, then backtrack toward B1–B9 to sit in the quieter section. One practical move: on an Alaska or American morning flight, aim to hit the far-left PreCheck line by 6:15 a.m. and assume a 10-minute walk if your boarding pass shows B20 or higher.
