It's only a matter of time for the EK39/40 to upgraded to an A380 methinks
That one-off flight only had the pax of a 777. Quoting what I said earlier about a few comments on a YouTube video:
"A388 has very good take off performance and could take off with a full load from BHX safely as it would not require full tanks of fuel to reach DXB, and that it performs very well on runways significantly shorter than BHX's."
If they were to start operating the A380 at BHX before the runway extension is completed, they would have to use the ENTIRE runway methinks if the plane was fully loaded.
We would get a third daily flight sooner than an A380 however.
