Wow I never realised that!
Meaning that if I had booked the flight with Alaska direct, I would have had Airmiles but no TP, but as I booked it as an AA flight I got nothing...
Actually, my initial flight was with AA but got cancelled. I got then rerouted on a AA flight operated by Alaska. Lesson learnt: if miles and TP is a criteria for you, you should be careful when accepting a rerouting....
