Orbitz and Travelport today gave indications that business travel is holding up despite recessionary concerns

. According to Orbitz Worldwide president and CEO Steve Barnhart, the U.S. travel market "is not quite as robust has it had been, but it is very solid. We see some weakness ... more in some of the discretionary leisure markets. We haven't seen it in major business markets, or the mainstream continental U.S. markets. We are seeing continued solid growth in our corporate travel business." Travelport's Galileo GDS, meanwhile, reported 2 percent higher year-over-year bookings in February, following a 1 percent increase in January and a roughly flat performance in the fourth quarter.
