True in a way,. but OltonPete is correc in a way, in that if there are flights from LHR-DXB and then on to Brunei or Bangladesh, what seats count as empty?
Having said that, OltonPete should not just ignore the LHR figures because they're "too difficult", it appears that the LHR load factor was below 88% for December (it would be 88% if the pax on the Brunei/BD flights had not gone to DXB and the pax on these flights had flown BA/EK instead.
Roughly, the December LHR figures were below 88% (somewhere in the region 80-88) and MAN figures were 83%
