US Airways has spent more than $20 million since 2006 to fix what had become persistent complaints about baggage.
"We have come a long way, but we still have a long way to go," said Bob Ciminelli, who was hired recently as the airline's vice president of operations at Philadelphia International.
One of his first moves was to have a different crew handle baggage for connecting flights than the crew handling local bags, cargo and mail.
Also, 30 ramp-information display screens have been installed at a cost of $2.2 million for baggage handlers and ramp workers to have more accurate information about an airplane's destination and departure time. The displays have countdown clocks so ground workers know how much time they have to load a flight.
