... you ask that Crewmeal but I think that is pretty standard for Turkmenistan....
They operate 3x weekly out of BHX and carried 2,004 pax for September (-34%) which equates to 59 pax per flight. They operate 2x weekly from LHR and carried 830 pax for September (-43%). As there were 9 flights in September, that equates to 46 pax per flight!!!
I cant think of any other situation where BHX carries more pax on a route that LHR!!!!
