Is it still worth getting a miles cards if i don't want to travel in first/business class?

Last min peak season tickets can be very expensive even in economy e.g. to jakarta, bangkok, kl or samui.

thats where miles come in very useful!

Miles worth more if you redeem on higher class such as Business, First or Suite.

If you're a bargain hunter you can always find cheap economy flights all around the world anytime! No need to redeem with miles cause you still have to pay for the fuel surcharge and taxes which might ending up similar to some of the sales outside.

Just get a miles card when you are anticipating a big ticket purchase

Yes!
