One of the best ways to save money on travel is to use rewards points to book airfare and hotels. Rewards points come in many forms, but credit card points are the easiest and most flexible to use since the points can be transferred from your card to a hotel or flight right when you're ready to redeem. Just note that credit cards can be a lead into debt, so be careful and try to pay off any balance at the end of the month to avoid getting into debt or accruing interest.
The other way to accrue and redeem rewards points is by being loyal to one airline and one hotel chain. The more you fly and stay with one brand, the better chance you have of getting more points, which leads to more discounts and perks like free flights and rooms.
