EK A388
Just for info, the EK A388 did have a 773 load on it (just in case the Airbus went tech and had to be replaced). The aircraft took off up hill with a tailwind and only used about 2/3rds of the TORA, so full and into wind on the current runway isn't a problem, shifting the current cargo loads would be though.
I think the speculation about EK is really funny, none of you have a clue about the load short of the actual load factor. BHX is constantly in the top 10 yielding routes in the EK system (normally in the top 4). Any decision to add a third flight (could already give you the timings and flight numbers but I won't) will not be based purely on the passenger load, although the earlier flight gives better connections to the sub continent and would reduce pressure on the 40, but on the huge amount of cargo coming from the current 380 stations to add to the home grown bookings, even SkyCargo can't keep up with demand on their LHR flights.
EK aren't stupid, the third flight is alive and well. It will start when TC thinks the time is right.
