Hello, I'm trying to book a multi city itinerary with more then 1 search segment per day. I can price it up on Matrix, Google Flights and Kayak but every time when it comes to the booking on AA I do get the error " You can't book connecting flights as individual flight segments".

I had this before when entering it directly on AA's website but always worked when going via a Google flights link. Is there anyway around it?

The flights in question are 16 AUG ORD-DFW-MIA-TYS and 21 AUG GSP-CLT-DFW-ORD (it's all about the BA tier points)

Thank you
