Maybe it has to do with how many A380s these US airlines operate .....
( .... was just a joke to make some buddies jump on this forum!)
If you followed the net yield of EK, it dropped continuously throughout the last years. There is the cheap ticket factor, to lure in customers, but the loyalty effect does not materialise. The customer of today is not stuck in the desert, as lots of EK employees. He choses the cheapest fare there is and does not care about the tail painting. Therefore EK is stuck as a low cost LH carrier, and this does not really pay. Most cherished premium seats are occupied by upgrades of almost give-away cheap tickets and by simply adding capacity EK increases that problem. Additionally the T+Cs of the frontline employees have eroded to the point that the motivation and therefore the service followed the downward spiral of the pay, attracting a different clientele, and finally putting off even more premium customers.
How to get out? EK needs to reduce seats, especially the discounted leading to over bookings in Y, and improve the overall service quality if they want to sell C and F tickets to the intended price.
The other path is to go the whole way as a low cost carrier, with all the trimmings. But i guess they know about the abyss waiting in such a case. EY and Qatar are just waiting for the neighbouring giant to stumble .... and they couldn't care less about genuine profits!
