the news noted:

JERUSALEM -

An Israeli couple going on a European vacation remembered to take their duty-free shopping and their 18 suitcases, but forgot their 3-year-old daughter at the airport.
The couple and their five children were late for a charter flight to Paris Sunday and made a mad dash to the gate. In the confusion, their daughter got lost.
The parents were unaware they had boarded the aircraft with only four children instead of five until they were informed by cabin staff after 40 minutes in the air. The child, accompanied by an airline staffer, took the next flight to Paris where she was safely reunited with her parents.
