Some recent posts on this thread have speculated about a possible slowing down of NF conversions. The chart below uses ftdashboard.net data, in particular flights to/from CWL, and shows when and how long BA's 744 and 777 aircraft have been to CWL in 2010-11. Green boxes indicate maintenance during which NF conversions took place. Blue boxes for 744 and red ones for 777 indicate maintenance that did not change the NF status. The very recent returns from Victorville (G-BNLU and G-BNLG) have not yet been confirned as NF or OF and are therefore shown in blue.
