Welcome to Flyertalk and the BA Forum jessgm_uk, you're very welcome here and I've nothing to add given the excellent replies so far but I'll post the link for the 777's below.

So, as previously said there are of course a fair number of 777 aircraft with different configurations and below you'll find discussion/different views on where's the best seats etc etc etc.

If you were to click show more at the bottom of the Wiki on the thread below you'll see the configuration types there too. Finally there are food threads too so you'll find info in the Club World thread and many others on the BA Forum Dashboard. Happy postings!
