Health & Wellness

AATC’s Health & Wellness Program was created to encourage and support a healthy lifestyle for our team members. We have adopted the term “Be… AATC” as our slogan. Through different approaches of being Aware, Active, Transformed and Changed, we have taken an initiative to better our team member's physical and mental well being.


Being aware is the first step to becoming healthier. AATC provides education through seminars, brochures, and demonstrations about healthy living and healthy eating. We also offer annual screening programs so employees are better aware of their current health.



Research shows that lack of exercise can be as lethal as smoking. AATC continuously adds new ways for employees to be active while at work and outside of work. We participate in weekly walks in the airport, have monthly walking challenges, and support our community by participating in fundraising walks in and around Atlanta. AATC also subsidizes a gym membership.


We are actively transforming our employees, not just physically, but also mentally. By providing healthy snack options in our vending machines, tracking our activities, and creating a new, healthy culture, we are transforming our team into healthier and happier employees.



Change can only happen from within. AATC’s approach to being CHANGED is when an employee begins to adopt a healthy lifestyle outside of work and are making an effort to improve their overall wellbeing.
