I think he may be alluding to the fact that any new service will likely be wanting to use the terminals during peak times. MAN has 2 runways, but not much available in terminal capacity when people want to fly.
BDLBOS, I think you could well be right and in fact I'd belatedly edited my post to raise this same point.
LAX LHR, re Hainan, in the routesonline item about 4 new destinations, it refers to the routes being in their pdf schedule file (or some such name) but not in GDS. What is the significance of that, if any? With 2 routes to Japan, LAX and TLV specified, it does make you wonder how far down the list MAN now is.
