Usually they operate a 2 class 77W to BHX. For this time of year, this seems like a pretty mediocre LF (although it is 66%).
However, some reports suggest this acft was actually diverting.
Seems like a fairly minor incident, but EK (and other ME carriers) tend to be a little heavy handed when it comes to discipline, so hopefully the crew won't be too harshly treated when they return to DXB.
