What is the best way to transfer money overseas while earning points or miles at the same time?

So far the ones which has points have not so good rates and total ripoff. I wouldn't recommend them.

You can try Transfernow which is base on how much you transfer as well as ot has better exchange rates which I have used so far. It is cheaper than M1 Remit and safe too. Transfer can be done with USD and other currencies but not in some currencies.

But in order to prevent money laundering, it has some step by step security features to follow.

You can use my referral code below to get a free transfer for the first time:

Let me know if you have any question. :)
