Great American Delivery Service, Inc.

Established in 2003 and based in Mount Prospect, on Chicago’s northwest side near O’Hare — which explains most of what the company does. Support runs 24/7/365.

Weight range is the useful number: anything from an envelope up to 10,000 pounds, carried on 26-foot box trucks, with semi-trucks available above that. So a single vendor covers a document run and a palletized freight move.

Airport proximity drives the specialisms. All drivers are TSA certified, the company handles next-flight-out shipments domestically and internationally for indirect air carrier clients, and it runs AOG work for aircraft-on-ground parts. It also delivers lost luggage out of O’Hare. Trade show logistics is a second niche, as is medical and pharmaceutical shipping.

Ground coverage extends across the United States and into Canada, with same-day service concentrated near the Chicagoland base. The warehouse is a cross-dock facility rather than long-term storage — holding, repackaging, palletizing, shrink wrapping and weighing.
