AFAIK, Enrich need more miles to redeem. But I can't say for sure.

AM/Cathay booking system can let you search for Awards and required miles, while MAS/Enrich online booking only show their own flights..?

KF also got Star Alliance partners, beside SQ.

Most ppl want to minimise cash outlay since AM passes on the fuel surcharge.

MH business class is ‘inferior’ compare to SQ, QR or even CX

Normally instant but maybe it’s during normal office hour? Not very sure.

Did redemption for AM and was instantly reflected after the call to Maybank

Nope. Coz the terminal can't connect to Amex

Same as you can PayWave or slot-in, but the terminal will come out with error because can't connect to payment gateway

VI by default 2x for local spending. If MUVI, then 5x for grocery

MUVI/VI is 5x for overseas spending.

Amex is 5x TP for local and oversea spending.

Of course other things override it like ewallet top-up, government payment, EzPay installment etc

Yes. actually quite straightforward for M2P

Whenever possible, swipe Amex for 5x TP

Oversea transaction, use Visa because u still get 5x TP and better conversion rate/fee

For MUVI, there's a bonus feature (giving extra TP up to 5x) when MU wins a PL game. But since MU is not winning much nowadays and also the timing/date requirement, it's not as easy to earn bonus TP compare to last time

count

just buy using ur card that's all. but if'm not mistaken, the free coverage is only for accident + some minor stuffs

it doesn't cover medical expenses etc
