why wasn’t a flight attendant with the child?
The flight attendant can't stay next to the child for the entire flight, although they should be checking on the child regularly. They money charged for the service is for the extra labor needed at the airport and for the, ahem, liability involved.
*The* money charged...not sure where the ‘y’ came from.
Since the customer pays for the airline’s liability insurance, we shouldn’t feel bad when the customer makes a, ahem, claim.
