It seems the travel rewards, specifically the ones redeemed via points, is managed by "Connexions Loyalty Travel Solutions LLC" for Ultimate Rewards, Thank You points & the FIA card services (probably World Point travel resumptions). At least the redemption site appears to be the same.

To my knowledge I don't recall seeing anything different from the reservation prior to the purchase that would have made it different from the others. I've only seen this BULK CHECK a few times, fortunately the flights for this year do not indicate this in the eReceipt, so hopefully they all count!

Spirit Incentives, they I believe, were used for those tickets purchased with the 15% off or "free" companion ticket with the Premier Thank You Card, different then the point redemption.
