I been to the Las Vegas for the past 2 LDW .If your heading home Monday or Tuesday GIVE YOURSELF LOTS OF TIME. Security is always backed up by the shear volume of people. Last year I headed home at 12:30 pm on a monday and I get to the airport at 9. I know this is crazy. But I finally got through a 11:00 am. I could hear people all through line saying we just missed our flight. Just keep it in mind.
