A friend at work has 60k miles that he needs to reinstate. The USAir page gave the options of paying cash and applying for a cc. Is this an either/or option for him? My thinking is if it is an "or" situation then he should apply for the cc and meet the reqs which will net him more miles. Also, we are unsure if reinstating those miles will make him eligible for USAirs Preferred status if those miles met preferred originally. Thanks!
