HP's "Today's News" currently leads with a story about unusually long TSA lines at LAS.
HP advises: "Plan on leaving an extra two hours for domestic flights at the busiest times, mostly 6-10 a.m., to get through security, three hours for international flights."
No source for any of the facts alleged in the news blurb is provided.
In contrast, KTNV News reports this afternoon that:
"At Harry Reid International Airport, Monday morning brought wait times of about 20 minutes for department passengers."
And they include a statement by the airport reading:
"Currently, operations are normal at Harry Reid International Airport. The Clark County Department of Aviation is monitoring the situation and communicates with our federal partners that operate here at LAS."

While matters can certainly change, I think HP's blurb as currently posted is unduly alarmist. I don't think there are currently grounds for passengers to add two more pre-departure hours to the two already recommended by TSA.
