I'm not sure RJET is in a position to even fly the C100, let alone pay for them, as things have deteriorated since that article was published a year ago.

According to the RJET investor conference call last week they are even cancelling future E-Jet orders and reducing block hours for two customers (presumably UAL and DAL) next year because they are not only short pilots overall but unable support the necessary E-Jet training pipeline due to internal training department constraints.
