For business, I'll likely be in economy short-haul and business for long-haul. Business trips will likely be CPH-LON, CPH-USA, and CPH-NRT/HND.
For status, BA is fine. You'll easily make BA Silver (OW Sapphire).
If you have a chance to get 4 segments on Alaska in, I'd go for Mileage Plan. It's probably the best Oneworld program, and you can also redeem miles for flights on Singapore Airlines.
