Last night should be OK. It will take some time to be posted.

What matters is transaction date, it can be posted later but transaction date is still 18th June, still entitles for cash back.
Posting date is only important if you want to maximize cash back and at the last few days of the month, if it is not posted in the same month, it will be calculated as following month's quota.

Unless the merchant terminal is at different timezone, like in Japan and Australia which are ahead of us.

Nope, no online. I'm also using GE.

I'm using AEON bank and only managed to pay for a while using PosOnline...
I haven't thought of other cards yet.

Submitted my CL increase on Tuesday's evening and it was increased yesterday! That was quick. Again, it's so stingy on CL. Only RM 3k increase.

Yes.

I paid for additional luggage using AmEx last month and no issue.

My cards were activated at KLCC, the place where I got my upgraded cards. The officer helped me to activate and my Gold cards were deactivated, not sure if manually did it because some forummers here still have their Gold cards active but cash back is combined at RM 50 max.
Nevertheless, even if it's cancelled, it may still be shown in your M2U, you will need to call CS to remove it from M2U. I did it because I prefer neat looking screen and will not confuse myself when I make payment via M2U.

Mine increased automatically. Minimum for Plat was 15k according to the officer, I got it and subsequently I applied another CL increase three months after that. So I guess if your current CL has achieved that, it may not increase another round. I came from RM 10k.

Differences can refer to post #1. Mainly is the travel insurance which is not important for me because I have company's travel insurance or will buy my own travel insurance when I travel for leisure. The coverage is pretty limited last I read in this thread.

However, I only appreciate the higher CL increase and also the shared hotline with VS cardholders. Can skip all the selections compared to calling its general line. The dedicated hotline itself justifies the upgrade, at least for me.

Upgrade cannot be instantly, so no matter what you have to wait for few days. At least that's what I know.

Yes. Everything if transacted on weekends.

I'm not sure what's the practice now but mine was indeed increased to 15k that time, in early 2015.

It depends where their payment gateway server is located at. If Emirates, since their base is at Dubai, I will assume they may follow Dubai's time zone which is 4 hours behind Malaysia.

So to play safe, I usually pay on Saturday's evening, by then even the latest time zone is already on Saturday.

Fortunately for me back in 2014 when I bought MAS ticket on Saturday's noon, it was captured as weekend, I remember it quite clearly due to the significance of this trip. I believe they may have already changed their server.

Pledging FD is a guarantee basically bank is not offering you any limit. Well, once you uplift, your card will be cancelled too. So, in a way you will need to keep the FD for your card to stay active.
Yes, you will earn interest based on board rate.

Any benefit using that AmEx?

Yes, AmEx only. Refer to front page.

Statement balance will not be shown as reduced... Check out your outstanding balance as it will be reduced.
Click on your CC transactions and you will see money is in already provided you are using M2U (instantly) or IBFT or GIRO later.

Check out your total outstanding amount, it should be reduced already. Statement balance will not show reduction.

I wonder why M2Cards looks unattractive now? Despite having so many different cards, it is my most favourite card now. I have CIMB CR, used to have HLB Wise but after its revision to RM 2k for RM 100 cash back, it is no longer attractive to me. I boycott all HSBC cards, their cash back is not true cash back %.

Moreover not all banks allow FDs pledging for CC application, you may need to check out those banks.

Yes.
