Do the miles expire with the credit card too?

[berlinlife06]

I don't have any credit card to ac***ulate miles on my frequent flyers programs. Instead, I travel or use certain services to add miles into my accounts. How is it with the Credit cards offered by the program miles? Is there anyway that your miles might expire? Or just having the card is a warranty that they will not expire ever?

That's a good question - I don't have a card with frequent flyer miles, but I would love to know if they expire, because I have been travelling a lot lately and was considering getting one.
