And you get 2 sets.
So with 2 credit card, you can accommodate 4 pax in a dining place (fairly simple place i presume) , good for those family that has only 2x access (dad / mom) or had to accomodate a lot of family member (like grandfather/ grandmother) .

Its' an optional path.

I use 3x different card to redeem 6 sets of food, to accomodate family member, instead of making them wait randomly outside and i enter the lounge.

The Smart Traveler app now allows you to register your credit cards, where you'll only need to show a QR from the app to enter the lounge, and also see how many times you have used it.

I registered a card at PPL and also received a bonus 888 points. Not bad.

yes
