The OP might just need to suck this one up and pay the fees.
Alternatively they could price up on ba.com and either use Avios to reduce the cost of paid tickets or use Avios to upgrade into a higher cabin, although BA slap on additional TFC's when upgrading which seem disproportionately high when starting in the US.
