Personally I dont think it will fold or be grounded (not forgetting JQ was previously flying as Impulse for what 4 years?), and as far as being pushed back into QF mainline is concerned, well who knows? I dont fly for JQ but I do certainly hope that they do not encounter any of the problems mentioned - I have mates who work there, and dont want to see them lose their jobs! The AN collapse sucked for 16,000 australians (luckily I was not one of them) and I would hate to see a similar situation occur
Anyway thats my 2 cents
