LOS ANGELES — A Southwest Airlines flight landed in Los Angeles with one more passenger than when it took off. A passenger gave birth shortly after Flight 623 took off from San Francisco on Tuesday and the Phoenix-bound jet diverted to Los Angeles International Airport. The woman was assisted by the flight crew and a doctor and nurse who were aboard, airline spokeswoman Emily Samuels said. She said hopefully the airline has a new customer for life. Paramedics boarded the aircraft and the mother and newborn, whose names have not been released, were taken to a hospital in good condition, Los Angeles Fire Department spokesman Erik Scott said. The aircraft was taken out of service for cleaning and the other passengers went on to Phoenix aboard another plane, arriving more than two hours behind schedule. — AP
