You know how there are numerous blogs, forums and message boards dedicated to all things Disney? People read and share to learn how to make the most of their trip. Things like how FP's work, need to make ADR's at the 180 day mark for certain restaurants, best place to see fireworks etc.
Well, there are other forums, blogs, message boards dedicated to all the ways to travel free or near free. On these boards people share what airline or travel credit card bonus is worth signing up for. How to make the spend requirements without really spending as much. Which cards to keep and actually spend money with, utilizing bonus spend categories, which ones to cancel, which ones to sign up for again. Whenever there is an offer to earn bonus miles for something I find out from those forums.
I just started this when we booked the Scotland
ABD and between DH and I we have hauled in 770K in miles. I'm helping my parents with the travel hacking now too since we are planning to do the London/Paris ABD in 2014. My mom knew what I was doing for our Scotland trip and asked if would be possible to do it for our trip with them too
