A number of prominent charitable organizations state that gifts of frequent flyer miles are generally not tax-deductible, because they are given to you by the airline and therefore have no monetary value in the eyes of the Internal Revenue Service.

You can contact the IRS at (800)829-1040 for a decision as to whether your gift would qualify as a deductible non-cash charitable contribution on Form 8283 – Noncash Charitable Contributions.
