I think most of the delay comes from airport congestion really. I am confused about taxiway foxtrot which might allows more pushbacks on to Delta - is that happening.
Hectopascals isn't the airport's fault - you'll need to change the CAA's view after several incidents where American crews have got it wrong- they are used to one simple scale of inches.
Remember Luton has a higher percentage of large aircraft/short turnrounds than many of its competitors.
Oh and auto frequency changes- again difficult - as unlike say Birmingham they are more variable- sometimes Approach needing to work traffic before London control to de-conflict inbounds and outbounds. So another reason is the crowded bit of the London TMA in which the airport sits.
