Officials at Phoenix Sky Harbor International Airport will boost security patrols and video surveillance in the baggage claim area following the arrest last week of a couple who allegedly stole some 1,000 bags from the airport. Passengers landing in Phoenix will also be advised of random ID checks when claiming checked luggage. Such checks were routine until a decade ago, when budget cuts led to the current "grab-and-go" system at most airports. Airlines and airports say they work together to prevent baggage theft, though reports of "mishandled bags" are ultimately chalked up to airline companies. Still, the Air Transport Association says the system works well. "The actual loss of a bag is unusual and a theft is even more unlikely," the group said in a statement.
