My boyfriend works on a cruise ship and has a brief layover in Miami so I’m flying in to surprise him on Sat. He will be departing from Terminal J to Panama that night, I will be flying out on American a few hours later. Will I be able to hang out with him in Terminal J; will they let me through security if my flight leaves from a different terminal? If not, any suggestions? We don’t get to see each often, so would like to make it last as long as possible!
