Thousands of weary travelers faced a third day waiting to reach their destinations Sunday as US Airways struggled to recover from the ice and snow storm that paralyzed airports in the U.S. Northeast, according to The Associated Press. The airline was still trying to find seats for 100,000 passengers systemwide whose flights were grounded by Friday's storm, spokesman Andrew Christie said. Computer problems, airline staffing rules and other problems slowed US Airways' attempts to clear the backlog.
