It’s believed that the contract is for four years, with pay rates comparable to Delta’s new deal (which we’ve already expected and the company had publicly committed to) and some improvements for pilots on scheduling (limitation on the kinds of trips the company can require pilots to work).
Delta’s pilot contract costs it $7 billion more over the course of four years. The exact costs to American isn’t yet clear because the details haven’t been released – although the increase likely wipes out the carrier’s current run rate of profits.
