I have an offer to upgrade as well. Been with Barclays since like 2005 I think? Had the US Airways card first, then it became Aviator Red, which I downgraded to the no fee card about 3-4 years ago. Minimal spend since then, like $500 a year. I am considering upgrading to Silver, but is it worth it? Are the 3x miles translating to 3x LPs?
