Hi Asdorset, 

 I recently wrote and article on the value of a frequent flyer miles http://travelcarrots.com/2013/03/25/how-much-is-a-frequent-flyer-mile-worth/ and would like to update the post http://en.wikipedia.org/wiki/Frequent-flyer_program. However, I have a conflict of interest and would like you to vet my contribution. 

 I would like to change/ add to the following sentence: 

 A typical ballpark figure is approximately 1-2 cents per mile based on discount (rather than full fare) economy class travel costs.[5] 

 Revised Text: 

 A typical ballpark figure for the redemption value of a mile is 1 - 2 cents when redeemed for economy class domestic flight. [5] However, it can be as high as 6.7 cents when used to purchase an upgrade from economy to business class on a domestic flight. [#]

 Thanks for considering making this change. 

 Best regards,
