Flying from jfk to tlv next week with my $400 round trip flights. I booked 3 seats me my wife and my 1 year old I booked a seat as well for. Now I plan on leaving the 1 year old and flying with only my wife. Am I going to have the third seat as an extra seat or is American going to give it away? Or should I cancel his ticket and get a flight credit and forsure not have an extra seat
