Interestingly enough the dynamic pricing is not always tied directly to the price.

I need a positioning flight WAS-ORD. All the none shop flights are priced exactly the same (low $200). One of the flights shows 10K in economy, all the rest 21K.

AA prices the none stop flights exactly the same dollar wise. All the flights are available for 7.5K on AA.

I would prefer UA flight so I can interline my bags to my containing * flight but with that price I just probably take AA and recheck my bags.
