Tips for SFO travelers

• Green = short wait (under 15 min). Yellow = moderate. Red = long lines — arrive earlier than planned.
• Use the history chart to spot peak hours at SFO and choose a less busy time to pass through security.
• TSA wait times at SFO refresh every ~2 minutes — reload for the very latest reading.
• If SFO shows PreCheck or CLEAR lane data, those lines are almost always shorter than the standard lane.
• SFO shows checkpoint and TSA PreCheck times by checkpoint, and every gate is accessible from any checkpoint once you clear security.
• Checkpoint A and Checkpoint B are the main public-facing reference points; use the live table first, then confirm your airline terminal if the line is uneven.
• The page is especially useful when PreCheck is materially shorter than the general lane, since SFO exposes both side by side.

How to use this page

• Use the live checkpoint cards first to judge current conditions, then use the history chart to see whether the line is following a normal peak.
• Confirm your terminal or airline before heading to security, since many airports on TSA Tracker have different wait patterns by checkpoint or terminal.
• Use the official airport links below if you need terminal maps, airport-specific security guidance, or the airport's own traveler tools.

What matters specifically at SFO

This page adds SFO-specific terminal context, airline routing notes, and 3 official airport resources so the wait-time reading is actually usable for a same-day trip.

• This page is currently backed by 11 live SFO checkpoint readings, so the terminal and checkpoint spread matters more than a single airport-wide average.
• SFO's security page is server-rendered with the live wait-time table already in the HTML, so the collector can scrape it directly without a hidden API.
• The table includes a freshness stamp. That lets us treat the data as live airport output rather than a planning estimate.
• The collector labels each checkpoint with its terminal area so travelers can tell at a glance whether a time is for International Terminal A, Harvey Milk Terminal 1, Terminal 2, Terminal 3, or International Terminal G.

Why this page is useful

• It separates live checkpoint readings from fallback estimates instead of hiding the difference.
• It combines the current wait number with terminal, airline, and airport-layout notes for SFO.
• It points to the airport's own maps, security pages, and traveler resources when you need to verify the airport workflow directly.

Get through SFO security faster

If this airport regularly runs long lines, these are the main ways travelers cut checkpoint time:

• TSA PreCheck vs CLEAR — compare the programs, costs, and which one is worth it first
• Official TSA PreCheck enrollment information
• CLEAR enrollment for travelers who use major hub airports often

Best arrival window for SFO today

Best off-peak window: 12 am - 1 am. Main risk window: 9 am - 10 am.

Current security timing is manageable at 4 minutes, but 9 am - 10 am is still the most likely stress window.

Related planning guides

Useful if you are still deciding when to leave or how much buffer to build in:

• TSA wait times explained — how the data works, peak hours, and the fastest screening strategies
• Best travel cards for airport-security perks — cards that may help offset PreCheck or CLEAR costs

SFO terminal and airline notes

• SFO labels checkpoints by letter and notes that all gates are accessible from any checkpoint, so travelers can choose the shortest line first.
• Checkpoint B has a mezzanine-level row that can differ from the main checkpoint row, so the airport is not fully uniform by entrance.
• Use the checkpoint closest to your gate area, but don't assume you must screen there if another checkpoint is shorter.
• The airport's own note says checkpoint letters reference the closest gates rather than limiting post-security access.
