Hello, I've just added an infant to a booking who will turn two between the outbound and inbound flight. When doing so I explained to the agent that my son will turn 2 between flights and he informed me that he could only assign a seat for him on or after his 2nd birthday. Which would be 2 weeks prior to the return flight. Is that correct? Or can they do it now? I don't understand why they are suggesting to wait until then knowing he would require the seat. Does that mean we are at risk of being downgraded from CW if there isn't an extra seat for him? Flight is GRU to LHR fyi.
