Passengers aboard Southwest Airlines jets will have access to Wi-Fi now that the airline has signed an equipment purchase contract with Row 44. Terms of the deal between Southwest and Westlake Village-based Row 44 were not disclosed. The airline will begin installing the equipment in the second quarter of this year and expects that its 540 aircraft will have Wi-Fi service by 2012. Row 44 developed a satellite-based broadband system using antennas and connections boxes. Mark R. Madler
