Continental Airlines is apologizing for sending a 10-year-old Massachusetts girl flying alone to New Jersey instead of Ohio.

Jonathan Kamens says he brought his daughter, Miriam, to Logan International Airport in Boston on Sunday. She was to fly to Cleveland to visit her grandparents.

He tells WBZ-TV that shortly after the plane landed in Ohio, his father-in-law called saying she had not arrived.

Kamens says for 45 minutes no one could tell him where his daughter was, setting off a panic among the family. She was finally located unharmed in Newark, N.J.

The airline says the error was caused by staff miscommunication. The two flights used the same doorway at the airport.

Kamens says the number of people who failed to do their jobs is "mindboggling."
