Are there any rumours on any other possible new long haul routes; wasn't there talk that Qatar might come back at some point with the 787? How about Etihad perhaps?
Qatar and Etihad consolidated and continue to grow agrresively at LHR, Garuda is a bit of a basket case with this on/off/maybe service frankly. I'm not sure the market is even close to being able to support what they're proposing.
Air China is coming back for the summer, although Korean is not.
