Sorry if this question is not related to the original post, but what does that statement mean? Mine says 6500. Does it mean that when I reach 10,000 I get 4 upgrade stickers?

Also, I currently pay $25 to upgrade from coach to FC since my flights are short hops. Is this $25 upgrade the same as the 4 upgrade stickers or are the stickers worth more?

Also, when do those stickers expire?

Thanks.
