American has such an expansive and complete network that if they merge with anyone other than US, there will have to divest to avoid monopolistic pricing power in the resulting markets.

I've not heard anything about American being broken up.

At Delta our CEO states, "capacity reductions are our leverage." Whoever merges with American is going to get more pilots than flying. JMHO.

ACL and I differ on one angle of this rumor. If American were a target, the timing of the Delta contract makes no sense. ALPA will want a JPWA in exchange for agreement to a merger protocol.
