I'm also concerned about TSA "sick-outs". As I understand it, the end of the current scheduled federal pay period is Friday 1/11, with direct deposits theoretically available on Tuesday 1/15. Since Homeland Security does not have an appropriation at the present time, I'm not sure how the feds legally pay anyone who works for the DHS agencies at the end of this week. Sick-outs will inevitably follow.
My wife and I are traveling on 1/15, starting our trip at IAD with a 1220 departure on Delta. I'll report back.
