Gotten my self into a bit of a mess

:
Booked with the family on TPA-ORD-CPH in economy/Go, where the TPA-ORD leg is on AA (I hate these AA segments)
What is my situation as to bagage (I have no status on OneWorld)?
The ticket states one 1 PC on the TPA-ORD leg
AA's website states 1 piece free for transAtl
But none for domestic.
It also states that 2nd bag would be USD 100 for transatl - and USD 25 for domestic.
So do we have the first bag free - or not?
What would the price of a potential 2nd bag be?
Trying to find alternative UA routing - but no luck so far.
