From Randy's June 28 MilesLink:
How many mileage-earning credit cards do you own?
None 22.22 %
1 44.44 %
2 22.22 %
More than 2 11.11 %
Considering the responses posted in this
thread, I'm shocked that almost one-quarter of the people have no mileage-earning card and only one in 10 have more than two cards.
