Carlson Wagonlit Travel's sales volume and number of transactions during the first half of 2012 both grew 1 percent year over year,

to $15 billion and 32.2 million, respectively. The rate of growth was in line with the travel management company's expectations. "Our first half performance for 2012 is solid given current economic uncertainty," according to president and CEO Doug Anderson. "Our customers are continuing to travel and are looking to manage their travel in a more cost-effective way by getting even greater value for what they spend."
