Air is not always the fastest choice. Every air shipment includes a drive to the airport, the cutoff, screening, the flight and recovery at the other end. Within driving range, a dedicated truck that leaves at pickup and drives straight to the receiver avoids all of those steps and often arrives first.
Ground also suits freight that is hard to fly, such as heavy machinery, long pieces or loads that do not fit an aircraft's door. A Sprinter van carries up to 3,000 lbs, a straight truck up to 9,000 lbs, a hot shot up to 16,000 lbs and a 53 ft dry van up to 42,000 lbs.
Air wins when the distance is too great to drive in time. AirFreight.com compares air trucking with expedited ground for each shipment and recommends the option most likely to arrive first.
