Searched for SJU airport information and found this thread. I was specifically looking to find out how the security checkpoints are set up at this airport. From what I read here, sounds like when my daughter arrives in one terminal/concourse, she'll be able to walk over to another terminal/concourse to wait for her friends' flight without any security concerns. Is this still correct?

Which actually brings me to another question/concern -- she won't get her baggage until the other flight comes in. Will be a minimum of 1-1/2 hours before her flight lands and the other one does. What will happen to her luggage, is this going to be a problem?

Thanks for your help.
