Virgin USA is expanding with the launch of Virgin Charter, an online marketplace for charter operators and customers. According to Virgin Charter founder and CEO Scott Duffy, the Web site allows customers to compare price quotes, book flights online and communicate with operators, including small charter operators who make up “the bulk of the industry.” Virgin also intends to create a “Virgin quality standard” to rate operators based on safety information ratings from auditing firms such as Wyvern. Charter providers pay a fee based on a percentage of the sale, while buyers of charter services pay no fee to use the Web site. A private, invitation-only beta version of the Web site will be available online June 12, followed by full-scale product launch at the end of the year.
