They are both miserable airlines with a gaggle of cabin crew and ground staff from developing countries who are there only for the money, have no national pride in the carrier they represent and quickly become complacent(that includes tech crew, alebit to much lesser extent)
QR maintains a semblance of quality only because they use draconian fear tactics.
Don't even get me started on the management brought in from the prestigious 'west'.
They are both overrated carriers. EK has lost focus and is a souless carrier because of its size. EY is still stumbling and falling and somewhat ametureish. GF is rampantly corrupt and the rest of the Gulf carriers are not worth mentioning.
