Having bounced around between Gold and Plat for many years, I do not recall certain aspects of OnePass Silver status. A good friend of mine recently achieved such status and has some flights remaining this year and was wondering what his upgrade chances will be. Like myself, he's based out of MCO and has flights remaining this year to PHX via IAH and SEA via EWR. I've been pretty successful with upgrades on these legs as I travel them fairly often. But, as I said, I haven't been Silver in a long time. Does anyone have any present knowledge about his upgrade chances or any other info I can pass along? Thanks for the help.
