OK, here's the fNWA FA story.

After flying a couple rotations with fNWA FAs from EWR to AMS, I didn't see what the big deal was about. The FAs were great and really took care of us up front.

A month or two later I flew a four day domestic trip with a fNWA CA. He told me how much nicer the fDAL FAs were than the fNWA crews and that they really seemed to go out of their way. I mentioned that I'd had the opposite experience, where the fNWA FAs were providing great service. We determined that if FAs were from the "other" side pre-merger they would try harder to make a good impression.

So.... If we had fNWA FAs, I'd introduce myself first and they assumed we were both fDAL pilots. If we had fDAL FAs, the captain would introduce himself first and they assumed we were fNWA pilots. The service was great the first three days. On day four I introduced myself to the fDAL crew on leg one and he introduced himself to the fNWA crew on the second leg. The service was below average on both legs.

As a side note when I found out I was flying four days with a North LCA, I was apprehensive. It turned out he was a great guy like 99% of the pilots here. He would even taxi on ONE engine.
