Okay so foreign *S does not get you any special boarding group. It's a bit of a shame - a very cheap and easy way to reward alliance loyalty. Even just guaranteeing zone 4 would be useful, though I think 3 would be reasonable.
I always got a better group on UA when I was E35K, and I appreciated that.
