Airport security lines are the headache that keeps on giving—and in worst-case scenarios, they can make you miss your flight. To help travelers dodge crowds while on the go (or let them know to hustle over to the airport post-haste), TripIt Pro, the travel organizing app from Concur, has added advance notice of waiting line times at TSA checkpoints to its various functions.

For the uninitiated, TripIt is a free travel app that condenses info like flight information, hotel bookings, car rentals, and dinner reservations into a comprehensive travel itinerary. TripIt Pro is an upgraded version that costs $49 per year, with a 30-day initial free trial.

Three hours before their flight shows up, TripIt Pro users will receive an alert detailing current security wait times. They can also check the app for time-stamped, real-time updates while traveling to the airport. Once they've arrived on site, they'll be provided with a map of security lines and nearby amenities like restrooms, restaurants, and shops.

So far, TripIt Pro’s new waiting time notice function is only available for passengers flying out of Austin Bergstrom International, Denver International, Orlando International, and Phoenix Sky Harbor International Airports. Additional hubs are in the works, according to company officials.
