Travelers want to go green and stay clean in the next year--and they don't want cell phones disturbing their peace, according to an annual survey of travel trends, CNET News reports.

"TripAdvisor, a travel Web site, surveyed more than 2,500 travelers globally, finding the top trends were concerns about germs, the growth of green tourism, and opposition to cell phone use on planes."

Specifically, the study reports that 78 percent of travelers believe that mobile phones should not be allowed on flights. That's fine--the next step is convincing the airlines that "flight mode" on an iPhone (or any other device, for that matter) means that no one is talking or using data services on their handset.
