Worldspan Launches Trade Sweepstakes June 10, 1998 Share 1 -- ATLANTA -- Worldspan launched a free air fare sweepstakes for travel agents as an incentive to book electronic tickets through the vendor. Eight airlines are participating in the two-month-long Ticket to Ride promotion, which was slated to start on June 1. A different carrier is featured each week. According to Sue Powers, the CRS' vice president of sales and marketing, agents who book and ticket e-tickets through Worldspan during the promotion are automatically entered into a weekly drawing to win two e-tickets on that week's featured carrier for travel in the continental U.S. The first participating carrier is United Airlines, from June 1 to 7. Other Ticket to Ride carriers are Delta, Northwest, TWA, America West, US Airways, Continental and American.
