Travel can burn a hole in your wallet, and it's only getting more expensive — hotel rates are projected to go up 3.7 percent and airfare 3.5 percent for 2018. Finding deals and discounts is one way to save, but spending a little more time on hacks to beat the system will stretch your dollar far.

Entrepreneur Travis Chambers, who founded a video marketing agency that makes social videos, has taken more than 100 trips in the past three years with his wife and two toddlers, and says he's saved a total of $60,000 with his tried-and-true travel hacks, averaging $20,000 a year in the past three years.
