A new page on HarryReidAirport.com lists wait times to pass through TSA security checkpoints at all gates. You can select A/B, C, and C/D gates at Terminal 1 and the D/E gates at Terminal Three and the boxed graphics show the estimated wait times for both the standard and TSA Pre-Check lines. Scrolling down a bit shows the expected wait times by the hour and day of the week in a bar chart with the average and maximum wait times. The inevitable disclaimer reads, “Note that these estimated TSA wait times can fluctuate by the minute and should not be used to plan a later arrival to the airport,” but at least there’s now a place to go online for current estimates.
