Car or a house purchase
Consumers planning a major purchase might as well get a free trip thrown in.
If you're in the market for a new car, check out DealerMiles.com, a car dealership voucher program that offers miles with nine major airlines.
If you're about to buy a house, check out mortgage lenders that offer partnerships with airlines to see if you can rack up miles in the deal. For example, LendingTree says on its Web site that it offers 1,250 miles on several major U.S. airlines per $10,000 financed.
Meanwhile, Miles4RealEstate.com says it offers 10,000 airline miles per $100,000 of real estate transaction value for brokerage, mortgage and title insurance, moving and relocation, and other home services.
