It’s also worth bearing in mind that players like myself exist who do enjoy operating older style airports. I fully agree, however, that it should be a player option to choose whether we want winglets or not so those players who only want winglets, can have them. If you’re operating a modern airport and have a Delta B763 on a route, all now have winglets so you wouldn’t want to see them without whereas someone like me who operates a Heathrow with a lot of 2015 liveries, loves the variety in winglets.
I have made a bug report regarding the modern United Rising Blue livery 767-300 having no winglets,
And a switch something like in my contract update could be cool, give players more choice,
