All of CXs 744 have AVOD, they are currently going through their 2nd upgrade in all three classes with a better AVOD and seats, particularly business class which has a horizontal flat bed as opposed to the ramp.

This is not true. In the previous config (74J and 744), only F and J has AVOD. Under the new config (74A), all classes will have AVOD.
Currently there are (to be confirmed) 6X B747-400s that has yet to be retrofitted to the new config: HOO, HOP, HUB, HUE, HUF, HUJ.

Quoting Readytotaxi (Reply 9): And the Gatwick based B777 will be the very last to get em.
Under the current plan the last three 772s to be upgraded will be G-YMMD (slated for return to service 26 Sep 2009), G-YMME (return to service 22 Oct 2009) G-YMMJ (return to service 24 Oct 2009). These are all LHR based aircraft. The last LGW aircraft to be slated for a return to service after upgrading is currently G-VIIT that is slated to return to service on 10 September 2009.
I believe the decision making process as to which aircraft are upgraded and when primarily reflects when an individual aircraft requires a major engineering check. This is because both BA 772 heavy maintenance and the 772 cabin upgrades are carried out at CWL.
Both the cabin upgrade and the maintenance check can be completed in parallel. So when the upgrade is made to coincide with maintenance, ferry flights to and from either LHR or LGW are halfed and the time each aircraft is out of service is also approximately halved.
Particularly in these difficult financial and business times efficiency considerations like these out weigh any others.
