Worth remembering that any amount over (I believe) £35,000 will be subjected to tax, whilst the initial £35,000 will be tax free.
So, 6 months money isn't so much after all.
I walked away from Virgin in 2010 with about £35,000 plus bits and bobs.
I was an FO with 3 1/2 years service - including the time I'd spent away on sabbatical. Worth taking in my case, as I'd moved on to other, better things.
But, if I was a long term BA Captain, I'd laugh this out of my email inbox.
What a joke.
