Here are the two qualifications that will facilitate my methods for traveling cheaply:

    1. Have an above-average credit score.  There are several scoring scales in use.  If you have a score of 700 or higher in any of them, you are good to go.  In some cases, you will be okay with a credit score as low as 680.
    2. Do not pay interest.  Pay your credit card balances timely so that you pay zero financing charges.  If you are paying credit card interest in excess of 5%, then you have bigger priorities than planning travel.
