I've mentioned this before, but around 6-7 years ago, the cheapest MAN-DXB was around £750. When I first starting regularly flying EK in around 2004, the price was £450.
QR are dragging EK & EY down to their level. How long can it continue?
On the other hand, J class flights have gone from around £1600 to £2400 over the last 3 or 4 years.
