Don't bother with economy, it's so small!!! I'm a small person and I was cramped in the middle seat on a 11 hour flight. Not fun. Go for business or first class for such a long flight if you can or be prepared to have trouble moving when you stand up. Also be prepared to have trouble sleeping too. Crew was awesome though, they were helpful and provided excellent service.
