So I have a AMS-LHR-DFW flight that will land in DFW at 5pm that day.

I also have another, separate PNR, DFW-OKC at 8pm that same day. Why I have two separate PNRs is a long story.

Anyway, when I check in my baggage (just 1) in AMS, can I request it to send straight to OKC? Also, will I have to pay an extra $25 to check the baggage?

AMS-LHR is on BA metal and the rest on AA metal if that makes any difference.

TIA
