Ana, I think you'll find staff travel is more important to you than it is to BA.
Of course it is important to myself and many other commuters who rely on it.
So how long can you afford full fare tickets before you have to call it a day?
I only work 50% and go to the UK every 28 days. I can manage to buy full fares for a while but it is expensive. It's not something I can do long-term but it's not game over yet.
