In 1995, Ingrid Perrino and Ron Starrenburg, self-proclaimed entrepreneurs, set out to redefine the way ground support services were being handled at O’Hare International Airport. Sunline Services was founded on the simple concept of assisting international airlines reach new heights by providing ground support services beyond expectations. In September of 1995, Sunline Services was opened. We are proudly in our 20th year of operation. We currently offer Passenger Services as well as maintaining a fully equiped Flight Operations Center.
