Children (2 years or older)
Children 2 or older are required to have their own seat; a ticketed adult fare. Children under 5 can’t travel alone under any circumstances.If you don't choose seats in Main Cabin or Basic Economy within 48 hours of buying tickets, we will attempt to assign children under 15 with at least one adult they're traveling with.
I am looking to book basic economy for my family, which includes a 3 year old. So the above means they will actually assign our seats right after booking, and not 48 hours before the flight as stated in the wiki on this page, right? I don't mind sitting away from my wife as long as one of us is next to our kid.
It's hard to imagine the AA lawyers (and marketing team) allowing a toddler to sit away from his family regardless of what is agreed to upon ticket purchase.
