What this means at Harry Reid International Airport
- The airport's wording: 'each liquid container must be 3.4 ounces (100 milliliters) or less, and all containers should fit into one quart-sized clear plastic bag per traveler.'
- The separate 'Security At LAS' page gives no rules of its own and points travellers to tsa.gov: https://www.harryreidairport.com/security-at-las
- TSA has been trialling self-service screening at LAS; the airport newsroom covers it, but it does not change the 3-1-1 limit: https://news.harryreidairport.com/tsa-testing-self-service-screening-at-las/
- LAS has a TSA PreCheck enrolment centre: https://news.harryreidairport.com/introducing-a-new-tsa-precheck-enrollment-center-at-las/
- Neither LAS page mentions CT or 3-D scanners, so whether liquids or laptops may stay in the bag in any given lane is not stated.
- TSA's national laptops guidance still says to remove laptops in standard lanes, with TSA PreCheck the stated exception.
- Medications, breast milk, formula and baby food are exempt from the 3.4 oz limit; declare them for separate screening.
