Two GAs on EK!
I personally have experienced GAs on EK twice in my travel. Once was at DXB while the second was at LHR. DXB, I am sure was slow traffic ahead since everything seemed normal until the very last moment when the pilot decided we had to go around.
LHR was another story. Terrible weather with gusts. Infact even when we did land, I remember the pilot made a sharp bank / turn like 100 ft from the ground at the last minute. It was as if he suddenly realised our approach was not in line with the runway. Scary ! to say the least . . .
