This makes no sense to me. The cost of having a copilot is one shared by every carrier. Eliminating that does not give one a competitive advantage as all carriers will get a similar cost reduction. It smacks an elitist "fuck employees, we hate having them, it's our money" That's not even considering the safety implications.
No one is "fucking employees" when that leads to bottom line growth in a crippling and money losing industry with insane regulations and red tapes like required no smoking signs in brand new airplanes.
