Seems like LGW is becoming the outlet for providing more capacity to the Far East, where it can't be squeezed in at LHR, so now we have:
Air AsiaX - moved from STN
Vietnam Airlines - starting soon
Hong Kong Airlines - starting S12
Air China - starting S12
What next, the return to LGW of Phillipine A/L and Garuda (the latter are getting 773's soon I think)?
