ET have taken delivery of the first of five reconfigured Q400s. The interior setup is 7J/60Y.
By 'reconfigured' I am thinking these are 2nd-hand aircraft, but perhaps I missed an order announcement. When all five are delivered, ET's existing one-class fleet (eight) will get the same treatment.
I would not have thought there was a lot of demand for J out of ADD but clearly I'm wrong on this. So at the end of this process, ET will have 13 two-class Q400s serving regional routes out of ADD.
ET are clearly doing some interesting things, with service to NA now with 77Ls (YYZ and I believe now IAD), and have just accepted their first Dreamliner. I guess building ADD into a regional hub is a big goal. Good luck to them.
