I am 100% sure this is the wrong place for this thread, but after searching for some time, I don't know where else to put this. Please feel free to move. Thanks.

I am new to this forum and to the whole concept of accumulating miles for future travel. Would someone please direct me where I can start? Also, very interested in what cards are the most beneficial, what airlines are the easiest to accumulate miles that can be swapped for other/partner airline miles. I have several frequent flier airline cards and some miles on them but have never used them and they eventually expired/are expiring.

I just booked a trip to Dominican Republic, so I will have to look at what airline that is and put the miles on my FF card.

I have heard that Inc. card is good for miles, but I don't have a business, so can't get that.

Would someone kindly point me in the right direction where I can start my reading here?
Thank you for your help
