Most business travelers must pay out of pocket.
The good news: Nearly all major U.S. airlines plan to add wireless Internet access on domestic aircraft, if they haven't already. The bad news: Most companies do not reimburse travelers who elect to log on in the air, according to a Business Travel News survey. Of the 230 respondents who guide corporate travel policy within their organizations, the majority (59 percent) said travelers are not reimbursed for onboard Wi-Fi expenses, regardless of flight length. Only 34 percent said companies would cover in-flight Wi-Fi fees, while seven percent said Wi-Fi costs would be reimbursed only for intercontinental or long-haul flights.
