Probably not. If you do OLCI, for example, and put in 4, it automatically puts in a $$ rate you have to pay for the 4th. My guess is that to get an agent to waive the fee, if you're checking in w/ a human, you'd have to be pretty lucky. I thought of checking in more bags when I was moving, but it turned out to be cheaper to send them Fedex Ground than it was to pay the fee for 4-5 bags. Cheers.
