I would have died on that hill and they would have either relented or kicked me off. No way am I holding my baby when I paid to have them safely in their FAA approved child safety seat. Here is the relevant FAA document https://www.faa.gov/documentlibrary/...ac_120-87c.pdf it states that an infant under the age of two may be held in the lap of an adult during ground movement, take off and landing. It is not required if the infant has an FAA approved child safety seat.
