It's true they do charge redemptions by the segment, but even then, they're often cheaper than AA on the same trip.
For a two-segment domestic (U.S.) one-way, I would be surprised if there were any Avios redemptions left that are cheaper than what AA would charge, since BA now charges 7,500 Avios for even the shortest AA nonstop. And since the OP's home airport is MAF . . . .
One can find two-segment redemptions from MAF to BOS, NYC, FLL, SEA (and probably lots of other destinations) for as little as 6,000 AAdvantage miles in Coach.
I think that Junior should credit to BAEC (or maybe even Iberia Plus if he has a chance of reaching elite status with them) if he expects to do any intra-European travel while studying in Ireland. Just one and one-half Premium Economy DUB-DFW-MAF roundtrips credited to IB+
in a single collection year would earn Iberia Plata (oneworld Ruby) status:

(And any Avios earned in an Iberia Plus account should be transferrable to BAEC, for those occasions when it is better to redeem through BAEC.)
