Replacement for the 146/RJ100 in the short term, and positioning themselves for the renewal of the QLink717 fleet in a few years.
Embraer must be happy as it will now put the E2 as the firming leader for this order, given that Cseries is further delayed.
However given QF's fleet planing history..... some Einstein will probably select the SJ100 or ARJ21 are just fabulous for the refleeting.....
