That is awesome if Xbox users can get those add ons and get to participate in virtual airlines.
Ive had MSFS 2020 since launch on PC and the amount of content and addon available are plentiful and have grown tremendously since launch. Hoping most of them can translate and come to consoles so more people can enjoy them.
The one add on / mod in particular that I enjoy the most is the Fly By Wire A320 Airbus. The best thing about it is that it is absolutely free and made by people who are passionate in flying. FBW's version of the airbus blows asobo's version out of the water. I dont know if they will release one for the consoles but if they do it is a must get in my opinion if you are into flying airliners.
