hi guys - anyone used the card for airport lounge in KLIA before?

few questions:
- do they check for physical card or can I show the aeon app with my card in it? MUST BRING PHYSICAL CARD
- can 1 card bring another family member, e.g my wife? just got back from lounge..if u get 3 cards eligible for entry can bring 2 others with u..this is plaza premium lounge klia2 lar..similar also PPL KLIA
- what about kids under 2. Are they allow to go in? not mistaken under 3 no need pay. check back ur lounge requirement

Cheers
