Can you link to a document suggesting BA want to move short haul LGW into LHR in part or whole?
Now don't be silly - our hero never lets the facts get in the way of a good argument.
The Policy Exchange report actually says
"It is easy to imagine, for example, that British Airways and Virgin will consider consolidating some or all of their services from Heathrow, by reducing or eliminating their Gatwick operations."
No authority is cited for this statement in the report (sound familiar?), so for the purpose of Windsorian's case, it is transformed into
this surprisingly well informed document of pro-LHR propaganda, makes clear the effect of even a R3 is BA & Virgin will move all their operations back to LHR.
Hmmmm.
