InsideFlyer magazine is reviewing Starwood Preferred Guest in our October issue and would like your input. If you would like to participate, please post your response in the thread with the pros and cons of membership in SPG and grade the program from A to F (A being the highest grade). You can include a plus or minus with the rating. You can respond directly to the editors at InsideFlyer at email@example.com if you would prefer. We look at earning ability, award choices, partnerships, elite-level program, rules & conditions, customer service, online service and the general pluses and minuses of being a member. You can rate any or all of these categories but please include an overall grade for the program. Thank you. You can see the completed review at InsideFlyer.com in October.
