Congratulations on your efforts P-T and welcome!
1. The BA members area of the BALPA forum has detailed payscales. Expect to start on approximately £55K going up to £75k as a 7 year longhaul F/O.
2. BA BALPA is suffering from a majority of "I'm all right Jack" members, so don't expect any improvement in the pension. BUT you can roll around laughing when, in a few years time, you are asked to go out on strike to keep the final salary pension scheme of those selfish individuals!!!!
3. I'm sure your sums are right - having passed the numeracy test.
