Does anyone know a quick way to prevent GSX give me Easyjet's logos on the ground vehicles when I'm in a Flybe plane, or BA when I'm in a Ryanair plane?

I'd rather have no airline colours and just have the colours of handling agents to be honest like Servisair, Menzies etc! 

 

I know it's down to the airline codes in the BGL file in the airport scenery. Is there a fast (and non-scary) way to edit these?

I think it depends on where you're parking. Like if you are at a easy position you get those trucks. You could modify the AFCAD.
