Trying to determine most efficient set of flights to make EXP (or come close)
I assume that the most efficient cost-wise fare to make EXP in a single set of flights in a *ONE3. Is that the prevailing view? Or does it need to be a *ONE4 to get to $67k flown miles? Or does that not work for some reason?
Also, is there a presently maintained spreadsheet that lets a user compare the cheapest fares and adjusts for currency? The AA website no longer has (or at least, it's now harder (for me) to find) a chart showing each of the different fares by starting location (which still has the currency conversion issue). I found a spreadsheet on the web, but it seems not to be current.
Many thanks. (I did do some searches ahead of time, but didn't see the answers for the above.) Thanks again.
