Student Airport Shuttle For only $15 each way, Regis students can ride to and from Denver International Airport (DIA) via the student-run Habitat Shuttle. All money raised will help support the Regis University Habitat for Humanity Spring Break Service Trips. This service is sponsored by the Office of Student Activities. Note: The shuttle only operates for fall break, Thanksgiving break and Christmas break. It does not run on weekends or during other breaks. PLEASE NOTE: After January 9th, 2014, we are no longer accepting shuttle reservations for winter break returns. If you have a last-minute flight change, please call the Office of Student Activities at 303.458.3505. Thank you!
