13. Send Flowers
Brighten someone’s day by sending them a floral bouquet, and score some points for yourself in the process. Several of the major florists are in cahoots with select airlines. For example, 1-800-Flowers has partnered with Southwest Airlines to give you 1000 Rapid Rewards points for each $29.99 order. US Airways and Teleflora have an arrangement that gives 15 Dividend Miles for ever $1 spend. FTD has partnered with multiple carriers including Virgin, Delta and United.

14. Open An Investment Account
If you’re sitting on a wad of cash, you might as well make it work for you. Investment strategy aside, you can earn some substantial airline miles just for opening a new account. Fidelity Investments is currently running promotions with United MileagePlus and Delta SkyMiles that can grant you up to 50,000 mileage points. That’s enough for some serious travel or upgrades. The caveat? You need to invest a cool $100K with them to get this tier of award. $25K still gets you 15,000 points, which is still pretty generous. Granted, this is more of a how to get free airline miles tip for those who can afford to buy a ticket!
