Corporate travel buyers are feeling optimistic about the coming year, according to a survey conducted by the National Business Travel Association Foundation and released last week. Nearly three-quarters (72 percent) of the 170 North American corporate travel buyers surveyed for the "2010 Industry Pulse: Business Travel Buyers' Sentiment" said the business travel industry is better today compared with one year ago, and 63 percent think it will continue to improve in 2011. In other survey findings, the average corporate travel budget was up 5.5 percent in 2010 from the previous year and will grow another 4.45 percent in 2011. It's important to note, however, that the most cited contributors to increased spending were higher rates and fares (67 percent) and an increase in airline fees (64 percent). Just over half (51 percent) of the respondents said their travelers will take more trips this year, and 38 percent reported more people will be traveling.
