I got today my $200 UA gift card credit. Charge was this Sunday-16, credit posted on the 19th ( I only saw it today, checked yesterday wasn't there, might be I checked before 1PM EST). I'm too new to Amex to know exactly when it updates, but it's around 1PM EST.
I just downgraded to Gold today.
I have one more question. Amex told me that the Plat card will be active until I activate my new gold which is coming soon, so I'm thinking to never activate the new gold card, leave the Plat card active, and get lounge bennies, any thoughts?
