Given the present scenario I don't think we need to be at all careful about wishing for a carrier such as EK on MAN-NYC. Bring them on. MAN currently offers just two flights per day to NYC, and those operated by B752. Not exactly overkill, and this thread has already mentioned the high fares which have resulted from this capacity squeeze. MAN has successfully supported far more capacity on routes to NYC in the past; a share of the seats on an additional B77W would be entirely within the ballpark of what the route has supported previously. Existing operators on MAN-NYC have had plenty of time and opportunity to upgrade their offerings but have elected not to do so (probably because of their own capacity dumping at LHR). If someone comes to take their cake away at this point, the US carriers would have only themselves to blame.
