Yoshi,

if you look at my profile you see I´m almost in the same boat except UA to which I credit all my US travel and some more to enjoy these valuable (for my patterns) SWUs.

So it´s between ROP and DC. Given you have status with TG until 2011: Why not filling your DC account and enjoy some much cheaper rewards out of it, perhaps even your US travel so you can skip OW and have lounge access enroute and in the US? <India-US with DC is 80,000 miles in Y, 120,000 in C vs. ROP 120,000 (Y) or 180,000 (C) for the use with any *A carriers>.

From what I read a potential merger LH/BD is not happening in the short/medium time frame.

F.R.

Edit: Just re-looked your profile to learn that lounge access won´t bother you
