Interesting that they know now (some weeks in advance) that this one aircraft will be scheduled for that particular flight.

I guess if that one aircraft isn’t used, they can swap it for a 737 800, depending on loads.

A quick look at Flight Radar suggests this aircraft is currently used for flights that aren’t very short at all! NQZ, HRG, DXB, and also LHR, so the front rows must be used for C class, I’m guessing…
