Frequent-flyer Miles
Trade or bartering of frequent-flyer miles is prohibited by nearly all major airlines, although an authorized medium exists for specific frequent flyer programs. Unauthorized exchanges of frequent flyer miles – of which several exist – are also useful examples of grey markets.

Famous quotes containing the word miles:
“The mountainous region of the State of Maine stretches from near the White Mountains, northeasterly one hundred and sixty miles, to the head of the Aroostook River, and is about sixty miles wide. The wild or unsettled portion is far more extensive. So that some hours only of travel in this direction will carry the curious to the verge of a primitive forest, more interesting, perhaps, on all accounts, than they would reach by going a thousand miles westward.”
—Henry David Thoreau (1817–1862)
