I've read most of this 22 page thread, but may have missed some here or there.

What (if any) effects would a DL/UA merger have on the NW/KL joint venture?

Is UA/DL merger talk all smoke and mirrors to distract from the probability of a NW/DL merger?

The NW/KL and DL/AF relationships seem much to important to breakup up for UA.

I'm sure its been discussed though.
