US Airways, which is, as we all know, the the result of a merger between America West and US Airways two years ago — officially became one airline in the eyes of the Federal Aviation Administration today as the FAA granted the airline a single operating certificate.

Yee haw.

Good news for the airline. Would be even better news if all employee groups at the airline were now working under single contracts.

But we all know that road is one with a huge ugly “Slow: Road Work Ahead” sign blocking speedy progress.
