Q&A with the Seat Expert

I’m going LHR -> Beijing on a daytime flight. So, what seat would you people recommend for economy, one that has a lot of leg room?

Is seat 39A on an British Airways 777 a window seat, or is it situated behind the last window?

I would like to know when British Airways will have finalised its modernisation to New Club World on their 777s on the Kangaroo Route (BA15/BA16)?

I’m flying a British Airways 747-400 in WTP. I want to know which is best: 12 B or 12 G and why?
