Again, it isn't hard to pay higher salaries if you subcontract out a much higher percentage of the work and keep far less of it inhouse.
I'm not saying any DL mechanic or any other employee should be happy with any level of outsourcing but the simple fact is that WN's business model from the beginning has been built around outsourcing much higher percentages of outsourcing than any US airline.
Given that so many accuse other people here accuse DL of leading the outsourcing of ramp, why isn't WN held to the same standard?
UA and US now outsource comparable amounts of their total maintenance budget and AA has made it clear that it is not going to continue as having the amount of inhouse maintenance that they have had in the past.
I don't know what Gil West will do in his new capacity but he has had responsibility for maintenance and ACS, the two areas of any airline that are most subject to outsourcing, so the notion that he will be outsourcing more is hard to believe given that he could have done it earlier if that was his bent.
DL is bringing more work inhouse because DL people can operate DL jets more efficiently than other carriers can do it contracted to DL.
