Hi,Im a 22 year old young adult residing in the U.S. Im a TOTAL noob at all this mileage redemption. I have read the Guides on this forum,but i still am confused. Can somebody fully explain to me the following questions. 1.How do i start from strach to earn frequent flyer miles/i have no traveled in 10 years and im only 22 years old,and i do not own any credit cards. 2.Iv'e looked and all i see is racking up points with credit cards,but im worried it will mess up my credit score,although i do not own any credit cards. 3.How do i earn the most frequent flyers rewards without a lot of risk,and the big riskers is there a site with a list of available big options for like 50k miles. 4.Is there other ways to earn FF rewards without signing up for credit cards 5.Is there a complete guide for free that i can view 6.What airlines would be best to sign up with in New york? Thank you so much!
