We just fly the 380 in c class LHR SIN LHR... it was amazing.

I'd say all the seats are about the same - other than the bulkhead, which I would avoid (not as much storage, weird angle of video monitor, etc). We were in the 2 middle seats in row 12. Seats were great and after a few walkabouts the cabin, I'd say all the seats are about the same.

As I posted in another thread, I'd agree with other posters that the first cabin is much better than the 2nd c cabin. Y class is behind the 2nd c class cabin - so noise makes its way forward.

Enjoy!
