With an airline reward credit card you can collect points towards any form of flight you would like, except to the moon that is.

You can use them for business flights to any destination of your choice. Or you can use them for holiday flights with your family.

The choice is entirely up to you.

However you need to keep in mind that there will be times of the year when you are most probably unable to use the accumulated points. You need to check out your cards terms and conditions for this. But for example, Christmas time would tend to be off limits for using points in return for flights.
