Absenteeism is still running high at the nations airports.

Absences Still High as TSA Predicts Airport Holiday Travel Crush

But I have seen statements from TSA several times now saying something along the lines of "While 99.7 percent of travelers waited less than 30 minutes in screening lines, three airports recorded maximum waits exceeding that time on Thursday. In Atlanta’s Hartsfield-Jackson, passengers waited as long as 47 minutes, the TSA said. "

When did a wait of 30 minutes become the acceptable? I would consider 30 minutes about 28 minutes too long.
