And with a bit of wiggle room, MyTravel and others could be mixed in. Also the FlyBe white would be a priority lol. And in the top photo, FlyJet only had 757s so another 752 operator there as well as BMI who are perfect as a second local at LHR so 2 birds one stone (BMI baby too at MAN 
). Plenty of others as well which are not massive fleet airlines and had a type or two so would just add to the lineup.
Just adding onto the bottom of this, modern MAN with airlines and liveries since 2003/4 till now would be a dream. Iām sorry to say Iād likely never leave the airport 
but Iād be spending on the airport big moneys lol.
