Jet In Time — Airport departure timing: check-in and | jetintime.com
Fifteen to thirty minutes in a standard lane at peak, a target of ten or less in PreCheck — and two rules that decide which travellers get stuck.
Standard security lanes run about 15–30 minutes at peak times. Peak means the morning and late-afternoon departure banks; outside them the same lane can clear in a few minutes, which is why queue estimates should use the top of the range rather than the average.
TSA PreCheck lanes are targeted at ten minutes or less. The saving is real but narrow: PreCheck changes only the security term of the count-back schedule and leaves the bag-drop cutoff and gate close exactly where they were.
On narrow screens, swipe or scroll the plate sideways.
The 3-1-1 liquids rule is the most common self-inflicted delay: containers must be 100 mL (3.4 oz) or less, packed into one quart-sized clear bag, one bag per passenger. A single oversized bottle triggers a bag search that can double a traveller's time at the belt.
Since 7 May 2025, travellers on US domestic flights need a REAL ID-compliant licence or a passport to pass screening. A non-compliant licence is not a delay but a stop — the podium turns the traveller back before the queue even begins.
The practical estimate: budget 30 minutes for a standard lane at peak, 10 for PreCheck, and add a re-screen margin if the liquids bag was packed in a hurry. Then feed that number into the count-back schedule in Departure Countdown: T-3 Hours to T-0 and the cutoff columns in Airport Deadlines by Flight Type.
