Sorry about that folks, but the "enter" key got in the way of my finger.

With all due respects to emmett_s, I have been wondering how FF miles are measured. Are the miles nautical miles? If so, then there is a lot less nautical miles between 2 points, than there are regular miles. With mostly all the airlines increasing
reward requirements or somehow making
rewards more difficult, it would not surprise me to discover that all these years I have been accumulating/spending miles that these were really nautical miles and I thought they were 5,280' miles. Also, do
the airlines that are based in Europe or elsewhere, convert kilometers to miles, whether the miles are nautical or not?
If these were nautical miles, then we should have about 15% more regular miles.
