Ditzyboy, you have posted a really long list of problems in short haul. Whilst I agree that all of these points may be an issue for some people, I really don't think that things are THAT bad.
I'm sure that the AO cabin crew will be a refreshing change, as they actually seem very positive about flying for short haul. AO have been operating services under the Qantas name for a while now, and Flightgirl is probably right, they do a great job, and this has been recognized by the company.
Its great for short haul to get 300 more permanents. We will get extra aircraft (even if they are clapped out 767's) and new flying routes. As our group becomes larger, we strengthen our position in the company, which will lead to more job security, and more diverse flying. There will always be a large casual workforce, but that is part and parcel of life in the 21st century!
