Renfro: Where did you hear it is how many miles a Platinum flies is what puts them ahead? Never to my knowledge has this happened and doesn't make sense as the gate agents and ticketing agents don't have access to this kind of info. It is supposedly based on 1. Time of check-in for that flight and of course, Silver Gold or Plat 2. What type fare Y,V etc you are booked under and 3. Date you booked it, earliest having preference. So for instance, which happened to me as a Platinum, is that I was booked on a T class and checked in quite early, ultimately a Gold got upgraded ahead of me on the plane b/c he had a Y or K fare or something also an early check-n, ..I am almost positive it works as I mentioned because that one instance upset me. Any comments anyone?
