I don't doubt that EK are filling their aircraft but this would more than double their existing fleet. They currently operate 117 B777 aircraft. Are the number of routes that could be served, viable?
Well, people said 50 aircraft wouldn't be viable, but here we are-
I attended a breifing once with a strategic planning guy- his story was he'd worked for BA, been tasked with looking at how much of a threat this upstart airline Emirates was and, no doing the sums, promptly applied for a job with them!
HIS story was they saw a market from the region of 650 Widebodies, and that more than half of them shold be EK.
I believe the suits believe we should be a 350 aircraft Airline.
Is that viable? Dunno, WAY above my paygrade- but they HAVE been right most of the time up till now.
Getting them through the airspace, onto a runway and then parking them somewhere might be a different story, however.
