Morristown, N.J.-based broker ExecJet USA recently launched a new Web site that allows travelers–or what the company dubs “travel hosts”–to post their flight details in search of “travel partners” to offset the cost. According to ExecJet CEO Pearl Bacchus, the host is responsible for booking the flight and paying the associated fees, while the partner pays the host directly through an Amazon flexible payment service account. ExecJet said it does not collect any money from the travel partner. “Our responsibility is with the host, and that’s where our involvement ends,” Bacchus said. “The details are arranged through the host and the partner.” Bacchus admitted that sharing flights is “a touchy subject,” but said she is confident the company is not violating any regulations. DOT regulations prohibit the posting of scheduled flights. “We’re not posting scheduled flights,” she said. “The host posts the flight and is responsible for changing or modifying details.” The Web site membership is free for the first 90 days, then $9.95 a month, she said.
