I did the switching routine for about 2 years. Then a friend suggested I try Excel. No miles! I said no thanks. Then she told me about free enrollment in their travel discount program. I tried it - saved more on my first trip than all the miles would have been worth. Mostly hotel discounts that super frequent flyers can probably get elsewhere, but for me it was worth it. Don't want to sound like spam, so --

If interested, email me.
