Seattle Times: Be prepared for holiday travel Eligible to use the fast-screening lane are members of U.S. Customs' Global Entry, Nexus and Sentri border-crossing programs and selected frequent fliers with Alaska, Delta, American, United and US Airways. Children 12 and under can go through the precheck lane with eligible passengers.Which means that if you & your spouse have children aged 13+ you're screwed no matter what ... TSA still pulls out some passengers for random full screening, but most get through without having to take off shoes, belts or jackets or remove laptops and liquids from carry-ons. Also exempt from removing shoes and jackets are passengers 75 and older and 12 or younger.... assuming that they don't select you for some random molestation & harassment regardless. Sea-Tac has 14 "backscatter" body scanners as well as 35 metal detectors. TSA is removing backscatter scanners in some airports and replacing them with less invasive millimeter-wave machines, but so far the agency has no plans to replace the backscatter scanners at Sea-Tac, said TSA spokeswoman Lorie Dankers.And unfortunately for you Seattlites, your backscatter units aren't among those being relocated to backwater airports where apparently the local simpletons don't mind being electronically stripped & irradiated. Also consider alternative grope- & scope-free modes of transportation: Take the train, busA new option this year for Northwest travelers is BoltBus (boltbus.com), with five to six daily nonstops between Seattle and Portland (four on Thanksgiving Day) and four to five between Seattle and Vancouver, B.C.
