Carlson Wagonlit Travel (CWT), the world's second largest travel management company, said its sales for the first half of 2006 totalled $1bn.
The TMC said the figure was a 10% increase on sales in the same period in 2005.
CWT also reported rapid growth of online booking by clients throughout the world.
In the EMEA region, online bookings rose by 77% and now accounted for nearly 10% of all bookings.
The biggest rise of 91% was in Australia where 18% of booking were now online while in the States, online bookings rose by 21% and now stood at 42% of all the TMC's booking in the USA.
CWT said there was a 17% increase in its consulting business in the first six months of the year with services now offered to clients in Australia, China and India.
The six months also saw the acquisition of Navigant International which doubled CWT's size in America.
Hubert Joly, CWT's president and chief executive officer, said: "Our success in the first six months of this year reflects the momentum that is driving CWT today and the progress we are making in implementing our development strategy.
"Our progress demonstrates the relevance of effective travel management to our clients and the strength of our value proposition.”
Travelport suffers £1.1bn net loss
Travelport, owners of Galileo and Orbitz, suffered a net loss of $1.1bn in the second quarter of 2006.
But the figure included a "pre-tax non-cash impairment charge of $1.2bn" which the company said arose from "the difference between the price at which Travelport was sold to an affiliate of The Blackstone Group and the historical carrying value of Travelport's net assets."
The company said revenue during the quarter had risen by 5% to $693m and cash flow increased by $35m to $221m.
Gross bookings also rose by 32% compared with the same quarter in 2005.
Jeff Clarke, Travelport's ceo, said he was excited to begin operations as an independent company after its sale by Cendant and "proud" of what he called a "solid performance" in the quarter.
