Hello. I'll be arriving on an AA flight from Miami into Terminal 3 at the end of the month and will have exactly one hour (assuming the MIA flight arrives on time) to make a connection on a QX flight to PDX. Is that enough time to get from Terminal 3 to Terminal 1? I believe I'll have to exit security and re-enter at T1. Any tips? I read somewhere that the fastest way can be through central parking.

Thanks.
