I fly Biz class to points all over Asia and the rest of the world and I am currently United 1K on my way to Global Services.

I love the Star Alliance airlines and the Star Alliance lounges.

But I can no longer tolerate United domestically. So it is time to switch.

Internationally, I think I will be fine. Korean Air instead of Asiana, etc.

I see Delta has status matching. Can any of my Delta friends give me any tips as I switch over?
