I am silver too. The perks are few. We CAN pick a seat in E+ (more leg room) on check in if one is available. And we qualify for “Saver” awards when redeeming miles. But being upgraded, like to business class, isn’t going to happen for us, sadly. . .

We do get 1 free checked bag - 70 lbs. and earn 7 miles per $1 spent.
