Read my comment again Luke 258...
Also. I have 3 good friends flying 777 in BA on their 2nd and 3rd year. We always talk salary (A pilots favorite topic as always) and I never heard them even come close to more than 100 grand per year. I guess you are special or maybe a FO for 10+ years? Older contract? Dunno.... If true- then hey! I'm happy for you!
