I'd either just scrape Silver, or I'd end up paying extra on my work flights for upgrades to keep status, which is something I'd really not want to do (give up enough of my time flying round the world at the back of the plane - don't want to start paying for it too!)

With UA I'll at least get economy plus chucked in, and the chance to upgrade UA and *A flights with miles, neither I get currently...

Cheers

Jon
