Collectively, Germany, France, Italy, the United Kingdom and Spain represent nearly 70 percent of business travel spending in Europe, and therefore serve as a "good barometer of the health of the entire European business travel market," according to the report. The markets have experienced steady collective increases throughout 2014, with 4.3 percent and 4.5 percent year-over-year increases in the first and second quarters, respectively. In 2013, aggregate business travel spending in those countries increased 1 percent to $177.7 billion. "While much of the European continent began recovering late last year, 2014 is shaping up to be a true bounce-back year for European business travel," according to GBTA. Business travel spending in Germany remains the most robust of the five countries, totaling $14.3 billion in the second quarter, a 7.5 percent year-over-year increase. While GBTA projects Germany's business travel spending to grow 10.8 percent in 2015, the association expects only a 7.4 percent increase in 2014 due to factors including declining business confidence, falling demand for German exports and the Ukraine-Russia conflict.
