you have a Delta Platinum and an AMEX Platinum Charge? if you do, thats redundant....but even worse...the Platinum charge far overpowers the Delta Platinum. The Delta Platinum dont even have complimentary access to the Delta Sky Lounge
it has no access to ANY other lounges either. if you have a Platinum charge, then you dont need to pay AF on ANY other AMEX except the Gold as
@Htrb-nvr-blk-&-ug-as-evr says. if this is the case, I would downgrade the Delta Platinum IMMEDIATELY to the Delta Blue. Unless you want free checked bag and shyt then pay the $95 per year for the Gold. otherwise the Delta Platinum is pretty much trash. its missing a TON of shyt that the Platinum charge has. the only thing it has that Platinum doesnt is the Companion cert which would cover your AF if you use it....and MQM status boost which I dont need plus you have to put $25k spend on the card. Which wouldnt be hard to do if thats your only card but if you are splitting spend with the Plat charge or any other card then you wont meet that goal.
you can read back through the thread to get a better understanding. AMEX Platinum is upgrade as far as travel. As far as everything else, no. Best to combine the Gold with the Platinum...something I will do eventually but have to sort out my current cards first because I have a lot.
