Southwest Airlines (LUV -0.8%) says it's "shocked and disappointed" by a request from the International Association of Machinists and Aerospace Workers for mediation over a new contract. Talks between the two parties have become heated.

American Airlines Group (AAL -0.7%) pulled its listing from Orbitz in a development that could create a divide in the online travel industry. Several other carriers have hinted about a similar move.

Delta Air Lines (DAL -1.1%) says it will add 1,800 flights attendants in order to keep up with its expanded flight schedule. A few cracks on a tightened capacity stance in the sector have started to emerge on top of Delta's aggressive plans.
