Rexxy, you forgot the debacle that was the ATR and got the ejet thing wrong.
Only a small number of ejets were leased the rest were owned. The purchase price of which was significantly less than a 737 (in the order of half).
The 170's were cheaper than the ATR's and the business owned them.
When I say owned I mean with debt financing not outright, and leased to themselves via the internal holding company. They might have been leased from themselves at high rates but that would be for accounting purposes and did not reflect the true cost of the machines.
The ejet removal marks a low point in alrline decision making, along with hideously expensive 330's, the decision to NOT take delivery of the additional ordered 777's, the decision to buy skywest, the ATR's and a raft of other cockups.
