Sorry people, but there seems to be a misunderstanding about the 50 airbuses. HKA have signed a memorandum of agreement to buy 50, they haven't actually bought any yet. So don't listen to the propaganda.
They're known for doing silly things just to get a bit of publicity. Example was that HKA announced that 777's were on the way and that they'd be headed towards Gatwick as of last January!!
As for the FO's, not many seem to be leaving, they're either low time or that they're stuck because Oasis aren't taking any of them since the two companys have decided to do some business together. Capts on the other hand, are indeed drying up, and what with no command course for the FO's then things are going to get a little tricky...
