BA are using cruise relief pilots for the A380 as they can't meet the training demand at present - perhaps a glimpse into cathays future too (350 pilots needed by end of 2016). They get a full type rating and will go in the sim once every 90 days to stay current. If your worried about the lack of experience the company should provide a full type rating on joining. I expect (even with the masses of extra sims and failures and re-tests and wasted instructor time it still comes out cheaper doing it their way). Numerous times SOs complain at being tested and checked on things they have never even been taught and then surprise, they need extra sims for training (how backwards and wasteful is that - don't judge them until they are trained and qualified) the system is a failure and I'm surprised it saves money. You are more likely to die from the 'white death' in your coffee than a SO though. Small changes can make a more pleasant experience.
anyhow back to the thread nice to see some positivity -
15) invest in the product its inferior to Emirates.
