Looks like Rex have put on all of one extra MEL-BNE return flight on the Friday and one extra BNE-MEL return on the Sunday for next weekend.
Not sure how an airline suddenly 'puts on' an extra flight at two weeks notice, when they have only a few planes and fixed rosters for staff. Maybe Sharpie will fly it himself.
Some one tod me REX wants to offload up to 30 SAABs and is looking to Q400s firstly for NJE and they will do some REX fill in flying and then as a SAAB replacement especially where QF are on the same routes and there is no security screening
Is it the same person telling you Rex is getting 777s? A few more Q400s for NJE sounds plausible, replacing the rest of the SAAB fleet with Q400s, a fairy tale of epic proportions... decent used Q400s are in the region of $10 USD-$20 USD million a piece, and leasing them will reflect that. Given a SAAB 340 is probably worth less than a million USD for a good one it's not going to be a good swap rate for something that only carries double the SAAB at much greater cost factor. It would make more economic sense for Rex to buy/lease new ATRs than go used Q400s, but even that will involve a lot of capital.
