I have dedided to stay with UA MP since moving to BHD. I'm a UA 1K, so the ability to earn SWUs are the main reason for me.

The only thing that rubs me the wrong way is the paltry miles UA FFers earn on the BD flights I frequently take to connect from LHR, and the fact that UA does not credit status bonuses on BD flights or codeshares. I'm considering opening a LH account solely for banking my BD flights - at 250 per flight they're prety much worthless on UA, but at 1,000 per flight on LH they'll add up reasonably quickly.
