In my opinion, Alliance are getting 32 (so far) E190 to replace their Fokker fleet in the longer run. The revenue from flying 12 or so aircraft on QF routes for 3 or so years would be swallowed faster than the first beer after a 10 sector mail run in the wet season. The E190s purchased are 14ish years old, for comparison the youngest B717 is 15 years old. QF are aiming to place firm orders for replacement regional/mainline narrowbody fleets within 9 months, for deliveries starting in 2 years time...once they get what they can accept out of the pilot groups involved, of course. But both Alliance and QF would be keeping options up their sleeve, the 3 year deal is flexible and can be varied without penalty, according to QF management (yeah, I know).
