There are a few ways to save money on travel costs. One way is to book your flights and accommodations in advance, as prices tend to go up closer to the date of travel. You can also look for deals and discounts on websites like Groupon or Travelzoo. You can also look for travel packages that include flights, hotels, and car rentals for a discounted rate. Finally, look for rewards programs from airlines and hotels that offer points and discounts when you travel.
