There's a more straightforward, sure, and ethical way to quickly earn miles:
Do microlending with the very reputable
Kiva organization.
- You can provide some outstanding help to hardworking people around the world.
- You can lend money using your credit card (via PayPal) and PayPal generously waives fees for Kiva (at least they did when I previously loaned money). And, of course, you'll get the points/miles associated with that lending.
- AND... you can get the money back! Once the loan term is over, barring the rare circumstances in which the money is not paid back, you can request 100% of your original investment back... to put back into your bank account or invest in more worthy entrepreneurs.
Is that not awesome or what? :-)
