I was waiting for an opening for 2 reward seats on EK from LGW and thought it was futile..... then one night at 2am I did a check (even though I had registered for auto upgrade) and low and behold they had the 2 seats available.
it was a rare find.
Dxb - lgw was wasta Z ..... otherwise they were not giving.
3 seats would be like a lottery.
