Is the miles earned through certain credit cards, the same as the miles which we will be able to travel?

Question

Certain credit cards like Miles (Discover), No hassle miles (CapitalOne) offer miles earned as rewards. Does this means we can travel that much miles we earned or is it a different calculation.

Answer 1

No. There is no calculation. You need to get a certain number of "miles" to get an upgrade or free ticket or magazine subscription or whatever.

The term "miles" referred to the miles that you traveled on fully paid tickets to earn the credit. Now, points can be earned many ways, but they are still called miles.
