Thanks for the help. Called American and fixed it. Now I'm back to a 3 hour layover in SJU. Much more comfortable with that.
If one of y'all could spell out the procedure for connecting, customs and whatever else needs to be done in SJU, going both ways, that would be helpful.

Also, how early do I need to arrive for a Seaborne flight from EIS to SJU (11 AM flight)?

Thanks,
Rick
