From what I’ve seen there are only a handful of real world airline liveries released in the sim so far and some of these I’ve only seen on static a/c. KLM, EasyJet, Air New Zealand, Spirit and Whizz to name a few. I’m thinking they haven’t resolved all of the licensing issues yet. Another example of over promising and under delivering in MSFS2024.
The majority of a/c either have manufacturers liveries or those awful ones from 2020 that I was hoping we’d never see again.
