curious... as a 1P (and soon 1K)... if i check more than 4 or more bags, do you think the ticket agent might do a waiver for excess baggage fees?

i know regulation says 3 bags of 70lbs each free for 1K/1P, but just curious if UA special accommodations for a 1k flyer might allow 4 or more bags (as a courtesy waiver).

Thanks if any tips.
