What must be done for any passenger traveling with an infant in Row 2DEF?

For any passenger traveling with an infant in Row 2DEF, it is required that they receive an In-Flight Documentation (IFD) from the cabin crew (CC). This procedure ensures that the safety and comfort of both the passenger and the infant are prioritized during the flight. The IFD serves as important documentation, which may include specific instructions or guidelines tailored to infants and their unique needs while onboard, such as assistance with safety protocols and general care.

Other choices relate to safety and practical measures for passengers but do not specifically address the protocol needed for traveling with an infant in that particular row. It’s crucial that the proper procedures are followed to ensure all regulations are adhered to, particularly when it involves the well-being of the youngest passengers onboard.
