there are many ways to earn elite qualifying miles without flying or traveling anywhere.

you can get 10,000 delta MQMs signup bonus, and Miles Boosts of up to 30,000 MQMs and 30,000 bonus miles when you spend $60,000 in a calendar year
if you are just a couple thousand miles short of Platinum status,by sign up the airlines credit card,you can earn up to 40000 Medallion Qualification Miles without doing a quick mileage run (ie, a flight for the sole purpose of accruing miles)
Medallion Qualification Miles (or MQMs) are Delta airlines points you earn towards elite frequent flyer status. 25000 elite qualifying miles gets you silver status, 50000 gets you gold, 75000 gets you platinum.
40000 mqms are nearly enough for delta Gold Medallion members without flying on the plane.

Hilton HHonors - Earn MQMs + Double Miles With Qualifying hotel Stays. The promotion requires you to stay a minimum of two nights. You must set your Hilton hotel Double Dipping earning option to points and miles.

There are two options to earn MQMs, variable and fixed. The variable gets you 1 MQM per dollar spent, and the fixed option gets you 500 points per hotel stay. If you plan on spending less than $500 per two night stay I would recommend you booking your stays using the fixed point earning option, since the variable only gets you 1 MQM per dollar spent.
