AT&T Inc.

Included among these locations are 178 travel plazas and fuel stops in the U.S. and Canada.

As part of the two-year $4.2 million deal, AT&T will connect Flying J's headquarters site and its 178 travel plazas, convenience stores, restaurants and truck service centers. The new AT&T network will be utilized for point of sale and inventory applications, including tracking fuel, merchandise and services sold at convenience stores.. For its customers, the new network will track fuel purchases through Flying J's loyalty program, earning points that can be redeemed for future purchases. In addition, convenience store merchandise purchases are tracked through Flying J's integrated inventory-management system, which notifies its headquarters database of type and quantity of purchase and automatically replenishes those items.

"Lightstream designed and engineered a network solution with the reliability and scalability we need to serve our customers today and into the future," said Bron McCall, Flying J's chief information officer.
