So are the A319s canned, going to MEL or SIN?
Peanuts.aero quotes
"
The A320s replace previously announced A319s due to the response to the recently announced Tiger Airways routes from Adelaide to Perth, Gold Coast, Hobart, Melbourne and Alice Springs"
I presume these new A319's are not on the assembly line yet, hence the changeover? Mabye there are a few spare birds out there also? I do think that the Adelaide market would have been better suited to the A319 though...
