Supposedly Pre-Check will be online in SEA, LAX and PDX in March. That's according to the always helpful PDX BR staff. I asked this morning and he said supposedly it'll be up and running by the end of the month. Of course, who knows if this is true.
The FAs on my flight said AS is "really making it a priority" to get it online and running. ^ While receiving my government sponsored massage in PHX on Thursday, the TSO said "pre-check will eventually be rolled out everywhere." T2 in PHX really, really needs it.
