An Austin, Texas-based startup has built an algorithm that predicts security wait times, which consumers can now access on iOS and desktop devices.
Company representatives spent a year working with the Transportation Security Administration to better understand staffing levels, patterns and a mountain of other factors.
It's based on flight schedules and how many lanes TSA has open.
The technology is currently forecasting checkpoints at the top 100 U.S. airports, including Denver International Airport, for up to 24 hours before departure.
Consumers currently have limited options when it comes to accessing wait-time estimates, which depends on antiquated methods.
DIA's homepage includes an estimated wait time that is based on a TSA agent performing a physical count via video cameras.
"The TSA will watch individuals as they go through the line, look at just one person and track them to see how long it takes them to get to all the way to the magnetometer," said Laura Coale, a DIA spokeswoman.
What's Busy is also preparing to add museums, national parks, restaurants and other line-prone locations to its website in the future.
