thinking ahead, what would you suggesti do now?
If it's honored, I'd just add as a lap infant later,for 10% of adult fare. I don't know if you can actually add it later, or what the 10% would be based on, but even if it's 10% of 1500 bucks, it's still only 150. And I'd guess (with no basis) that chances are good at getting a CSR to add a later-born baby.
