XPT,
The plan was that if approval took some time that the spare 320's would be filtered through the JQ network. However QF gave up this option when they sold the majority stake in JQHK down to 33% in an attempt to get operator approval. Now the HK board have refused the allow 'their' 320's to be used. QF/JQ can do nothing about it because they're only a minority owner, and those planes are now parked.
The question is whether QF is footing 33% of the bill in Toulouse, or the whole lot. Depends on their purchase contract. I doubt the other owners would be so happy to have their planes parked if they actually had to pay for it...
