BTW, US Airways f/as just ratified their T/A today. They did maintain their scope language which is their job protections. So if there is a merger and if there are any overlapping that could create job losses, you have to hope that AA employees protect their scope, or they will be effected.
US FAs did not ratify a TA today; US and AFA negotiators reached a TA today that must be ratified by the membership before it's effective. The last TA was rejected by 75% of those voting.US Airways F/A just ratified a T/A today, and got to keep their scope language.
