I believe what's happening is that because MAN seems to be gaining an aircraft every 6 months (or less) over the past couple of years, the expansion at LPL is hardly being noticed as it appears to be more measured.
Collectively a MAN/LPL fleet combo is going to be 22 or 23 strong by the time the London Olympics comes along. Which makes me wonder would have happened if both LPL and MAN were abandoned in the 1950s and Burtonwood used as the Northwest gateway instead.
