Yes. The general rule is that the airline you're redeeming on will tack on the fees, surcharges, and taxes of the airline you're flying on. It works to your advantage when redeeming BA on AA (35K to Hawaii but low fees) or BA on LAN (South America and low fees) but against you if you ever need to redeem AA miles for a BA flight.
