I went through five Elite agents before I received a straght answer. I just wonder if it is the correct answer. I paid with miles for first class; one leg had no F seats. I was placed on standby (by the THIRD of the five agents; the first two did not even do this). My question was (finally answered by the fifth agent) what is the order of standby upgrades if you paid with miles:

1. Plat used miles

2. Gold used miles

3. Silver used miles

4. non Elite used miles

5. Plat no miles

6. Gold no miles

7. Silver no miles

True? Thanks.
