I lived in MSP, but I'm with UA specifically because of E+.

I'm tall, mildly claustrophobic, and not affluent enough to fly F or even C, a real consideration when I make at least one, sometimes two flights to Asia per year.

If UA ever drops E+, I'll be back with NW, which offers the advantage of nonstop service from MSP to Asian and European gateways. If NW ever offers something comparable to E+, I'll be back with them in a heartbeat, but for now, sitting in the back of a 747 on a flight to NRT...ugh!
