I just flew on AA from Seattle (Sea) to Tampa (tpa) .

Looking on BAs tier point calculator i should receive 30 points for the Seattle to Tampa route however i only received 20.

The flight was Sea to DFW and then DFW to TPA because AA dont fly direct . When i look on Bas site that routing is 20 points .

My problem is that i have 590 points and the "missing 10 points would get me to the magic 600 level. My year finishes shortly and i dont have any trips planned.I only took AA as it earnt me the sufficient amount of points or so i thought..

Any suggestions at all please?
