They are 'okay' those 330's but Economy really is packed for leg room compared to the 777 I find myself on the Doha-MEL/SYD routes. There is a very distinct difference. Flew out of MAN on a 777 and to MEL on a 777 and then MEL- Doha on a 777. However the Doha to MAN leg on a 330 is torture if you're in economy.
