Priority boarding is quite reliable. But for chosing preferred seats you should absolutely call AB to reserve those seats. If done online via AA there are many reports that those seat assignments are thrown out of the system 30 hours before flight when boarding starts, as AB charges for those seats and seems not to bother to check if those pax with assigned seats by third-party systems hold status.
