The Global Business Travel Association Foundation, the educational arm of GBTA, has published the 2012 Ancillary Fee Handbook, Who Charges What, When & Where. The foundation conducted research into extra charges over the past year, after learning that only 21 percent of travel managers are tracking such fees, even though the extras account for more than 8 percent of total travel spend. The study ranks more than 40 airline, hotel and rental-car fees and identifies the most problematic ones for travel management. Those that caused the most trouble were the least predictable, couldn't be paid in advance and were difficult to track individually, researchers found. Based on those criteria, the most troublesome ancillary fees are:

1. Airline fees for soft drinks
2. Airline fees for headset use
3. Airline fees for movies and videos
4. Airline fees for food
5. Car-rental fees for toll passage
6. Hotel-related fees for Internet use
7. Hotel-related fees for parking
8. Car-rental fees for late returns
9. Car-rental fees for drop-off or one-way rentals
10. Car-rental fees for fuel charges
