Delta Air Lines, for the last year, has been employing a variable model to set the price of award tickets on Delta-operated flights. The airline has been charging more miles for high-demand flights. The carrier now looks to be using the same model with Virgin Atlantic, its partner. Normally, airline frequent flyer programs priced tickets based on location and inventory, only charging more if there were fewer seats available on a given flight.

Delta, in the last year, changed that, and now the airline prices tickets based on demand and current availability. This isn't necessarily bad news for flyers as there are plenty of deals to be snagged. Case in point, Delta recently offered award tickets from Haneda, Japan to Minneapolis, Minnesota for 50,000 miles each way - 10,000 miles cheaper than other carriers. On a side note, business class fares don't reflect these type of great deals with dynamic pricing as of now.

Currently, Virgin Atlantic is the only Delta partner that uses this pricing model. Though Delta has not come forward with plans for Delta's other SkyTeam partners, if the model finds traction, Delta's SkyMiles loyalty program may introduce its variable pricing to 20 other carriers worldwide.
