Advanced self-service technology is emerging as a cornerstone of efficiency and passenger experience in the aviation industry’s rapidly evolving landscape. Initially associated with check-in, the technology is now reaching every sector of the airport industry—from immigration to bathrooms to bag handling.
Airport operator Houston Airports has partnered with restroom management company Trax Analytics to use real-time data monitoring and smart vending machine technology to ensure that its free period products are always available to airport guests.

As a result of this partnership, George Bush Intercontinental Airport (IAH) now offers these products through the smart vending machine Aunt Flow. The Trax Analytics SmartRestroom technology, integrated with Aunt Flow dispensers, enables Houston Airports to monitor supply and refill the dispensers in real-time, as it does for other bathroom necessities such as toilet paper and paper towels. IAH is the first airport to implement this technology.
Claire Coder, founder and CEO of Aunt Flow, comments, “According to a 2013 study by Free The Tampons, 86% of menstruating people have started their period unexpectedly in public without the supplies they needed. Airports providing menstrual products at no cost removes a significant stressor for travelers. It’s a low-cost, high-impact way to improve passenger comfort and satisfaction.”
