What is a good method of earning mileage for airline travel- both domestic and international?

Is there a good program or credit card or something that helps earn flight miles? I fly often and need to start earning reduced cost or free travel.

Thanks!What is a good method of earning mileage for airline travel- both domestic and international?Sign up to the frequent flyer programme of the airline, and always use them or other airlines affiliated to the same alliance. That's the best way to get the air miles, and then when you have enough you can use them for free flights or even upgrades (handy on international flights).
