US Airways announced Tuesday plans to operate nonstop service between its Philadelphia hub and Tel Aviv, Israel, as the carrier moves to expand its international service. The service, which is set to begin in July 2009 with the first tickets sold early next month, is in response to strong demand, said Michelle Mohr, a spokeswoman for US Airways. "What's being cut is unprofitable flying in light of ultra high fuel costs," she said. "With Philadelphia-to-Tel Aviv we've known the demand is there. We've talked about adding this for quite some time." The service is subject to approval by the US Department of Transportation and Israeli government. The airline will offer one daily nonstop flight. The Tel Aviv route would be the longest nonstop segment in the US Airways network. Longer-range Airbus A330-200 aircraft set for delivery in spring 2009 will operate on the route. US Airways began service from Philadelphia to London's Heathrow airport in March 2008.
