Flown on this route a few years back, went LGW-CLT-SFO on the 767-200 and returned to LGW on the A330 via PHL. CLT very easy to connect through, service was good and the FA's sound like Jodie Foster with their North Carolina drawl. Check out seat guru for a seat map which shows the best seats. The IFE on the A330 was very good.
