I have Amex Plat travel and I already hit the 4 lakh milestone and got the 50k rewards (including bonus rewards). I've seen some people getting another offer from Amex wherein if they spend 3 more lakhs after that (so 7 lakh in total), they get either 10k additional points or 20k taj voucher. Did anyone else get that offer? If yes, how do I get that as well?
