I'd suggest looking at the relevant thread on FlyerTalk. They have threads for user experience with the different airlines.

Depends on the lounge program. The Platinum has access to the Centurion Lounges, Priority Pass Select, Delta Skyclubs and Airspace Lounges.https://www.americanexpress.com/us/cred ... num#detail
