I was able to snag a morning seat to PBI on Thursday. The inventory is incredibly tight but after about 30 minutes refreshing periodically, I saw one seat open up (and quickly disappear) on each connection point: CLT, ORD, DCA and DFW. (I took the last CLT seat).

During my long chat with the EXP agent, she said that AA re-opens station operations in three stages: Day One is limited service (undefined but apparently less than 50%); Day Two is 50% service; Day Three is normal operations.
