Tips for ORD 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 ORD and choose a less busy time to pass through security.
• TSA wait times at ORD refresh every ~2 minutes — reload for the very latest reading.
• If ORD shows PreCheck or CLEAR lane data, those lines are almost always shorter than the standard lane.
• ORD is large enough that terminal and checkpoint choice matter more than the airport-wide average alone.
• At O'Hare, the best move is usually to trust the live checkpoint spread and not the assumption that every line is equally backed up.
• If you are flying international out of Terminal 5, treat that as its own security workflow rather than an extension of the domestic terminals.

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.

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

ORD terminal and airline notes

• O'Hare splits departing passengers across Terminals 1, 2, 3, and 5, with multiple named checkpoints in the busiest terminals.
• Checkpoint numbering matters here because different terminals run very different hours and screening mixes.
• Terminal 5 is operationally separate enough that travelers should plan for its own screening rhythm rather than assuming domestic-terminal behavior.
• United drives the biggest volume in Terminal 1, while American dominates Terminal 3, so those two terminals shape most same-day congestion.
• Terminal 5 handles the international-carrier workflow, while Terminal 2 carries a smaller mix including Delta, Alaska, Spirit, and Air Canada.

ORD airport-specific notes

• Chicago O'Hare can look calm at one checkpoint and much slower at another, which is why checkpoint-level data matters here more than a single airport average.
• This page is especially useful for business-travel windows when ORD security can ramp up quickly in Terminals 1 and 3.
