Here’s the Jetwire message:

“Since the merger closed, we’ve been working steadily towards a Single Operating Certificate, or SOC. On April 8 we expect to receive our SOC from the Federal Aviation Administration.

“Today, both American and US Airways operate under their own certificates. With SOC, the FAA recognizes American can legally operate as a single airline.

“Achieving SOC is a major milestone, but it does not mean that our integration is complete. While some of our operating policies and procedures will remain separate at SOC, the majority of our flight, maintenance and dispatch procedures will be identical for all flights that we operate.”
