Hi all, this is my first post on the AA forum, so please be gentle...

I've been searching and reading information about connecting at MIA, and what I've read alarms me somewhat.

I've got a trip next week LAS-MIA-MCO, which has a change a planes at MIA. The connection time is around 90 minutes. From what I've read, it depends on which terminal the first flight arrives at whether or not I need to leave the terminal and re-pass through security. Is this correct?

If I do have to leave the terminal and go through security again, I get the feeling 90 minutes may be cutting it fine.

Am I worrying needlessly here, or should I prepare for the worst

Cheers,
Rick
