American Express Platinum Travel Credit Card

Pros

• If you have Amex plat travel then you can do the 4L milestone - no brainer
• Just use a milestone based card like Amex Plat Travel. 2.2L yearly will get counted towards 4L milestone. Over 6% returns including a 10k Taj Voucher.
• Axis Atlas or Amex Plat Travel should help you to get max returns

Cons

• I've following cards which have reward points available: 1. Infinia 2. Atlas 3. Amex plat travel
• For context: I do have HSBC Travel One card (10k points), Amex Plat Travel (50k points).
• With the knowledge that Amex Plat travel and Axis Atlas have been discontinued, there are only a handful options left for your profile.
• I have amex plat travel already and while that can be my primary, I was wondering if IDFC Indigo could offer better benefits?
• Suppose I use amex plat travel till now for flight, hotel bookings on travel aggregators to achieve my milestones (through gift voucher, else direct)
